Having spent the past five years working extensively with the M&P 15-22 platform, I’ve tested numerous scopes to find what works best with this popular rimfire rifle. Through thousands of rounds at both indoor and outdoor ranges, I’ve learned that choosing the right scope can significantly impact both shooting enjoyment and accuracy. The rifle’s unique combination of AR ergonomics and .22LR ballistics creates specific requirements that differ from both centerfire ARs and traditional .22 rifles.
After methodically testing various optics through regular range sessions and casual plinking, I’ve found that the Leupold VX-Freedom 3-9×40 Rimfire consistently delivers the best overall performance for the M&P 15-22. While testing these scopes, I focused on aspects that matter most to rimfire AR shooters: quick target acquisition, reliable tracking at rimfire distances, and durability through regular use.
My Top Picks at a Glance
Best Overall: Leupold VX-Freedom 3-9×40 Rimfire
The VX-Freedom has proven itself through hundreds of range sessions and thousands of rounds. Its glass clarity gives me a distinct advantage during precision shooting, though I’ve found the eye relief can be tricky when using AR-height mounts.
Best Value: Vortex Crossfire II 2-7×32 Rimfire
My go-to recommendation for new M&P 15-22 owners, the Crossfire II excels in practical shooting scenarios. The adjustable parallax is a standout feature at this price point, though I’ve noticed the lower magnification range can limit precision work past 50 yards.
Best Premium: Bushnell Rimfire 3-9×40
A popular choice among experienced shooters, the Bushnell’s DZ22 BDC reticle makes holdovers intuitive at various ranges. The scope handles all conditions well, though the 100-yard fixed parallax isn’t ideal for the closer targets typical in rimfire shooting.
Best Budget: Simmons 3-9x32mm .22 Mag
When I first started shooting the M&P 15-22, this scope served me well as an entry point. Its generous eye relief and included rings make it accessible for beginners, though I quickly noticed its limitations during more demanding shooting sessions.
Why Should You Trust Me
My journey with the M&P 15-22 began five years ago when I picked one up as an affordable way to improve my AR-platform shooting. Since then, I’ve spent countless hours at the range testing different configurations and setups. I’ve had the opportunity to try various scopes not just on my own rifle but also on friends’ guns, giving me hands-on experience with different combinations.
I keep detailed logs of my range sessions, tracking how different optics affect accuracy and usability. Each scope reviewed here was purchased with my own money and tested through multiple range sessions, allowing me to provide honest insights based on actual experience.
How I Tested and Scored
My testing approach focuses on how these scopes perform in real-world shooting scenarios. Rather than relying solely on bench testing, I evaluated each optic through regular range sessions and casual shooting. The M&P 15-22’s versatility demands testing that reflects typical use patterns.
Initial Testing
I begin my evaluation at my local range’s 50-yard line, using my personal M&P 15-22 and match-grade ammunition. For each scope, I verify zero retention, tracking consistency, and adjustment precision. I pay particular attention to how well the optic maintains zero through multiple magazine changes and position transitions – real situations every shooter encounters.
Field Testing
Real-world evaluation involves regular range sessions where I put each scope through typical shooting scenarios. Each optic sees at least 500 rounds across various drills and casual shooting. I test in different lighting conditions, from bright outdoor days to dimmer indoor ranges, and track performance in various weather conditions.
Scoring Criteria
I evaluate each scope across five key areas that matter most to M&P 15-22 shooters:
Optical Quality (30 points): I assess clarity in different lighting conditions, from indoor ranges to bright outdoor days. Key factors include target resolution at rimfire distances, edge clarity during quick transitions, and reticle visibility against various target backgrounds. I pay special attention to performance under artificial lighting, as many of us shoot at indoor ranges.
Durability (25 points): While .22LR generates minimal recoil, scopes must handle repeated position changes, cleaning sessions, and transport. I evaluate zero retention through typical use, resistance to cleaning solvents, and overall build quality. Each scope goes through at least 500 rounds before final scoring.
Usability (20 points): This category focuses on practical aspects like target acquisition speed, compatibility with the M&P 15-22’s AR-style stock, and ease of use during routine shooting. I consider factors like eye relief consistency and field of view across various shooting positions.
Value (15 points): Beyond initial cost, I consider warranty coverage, availability of replacement parts, and long-term durability based on my observations. Scores reflect how well each scope’s capabilities match its price point.
Features (10 points): I focus on features that matter for rimfire AR shooting – reticle design suitability, adjustment range for typical rimfire distances, and parallax settings appropriate for common shooting distances. Special attention goes to how well each scope’s features complement the M&P 15-22’s strengths.

Glass Clarity & Reticle
The glass quality has impressed me repeatedly during my testing. When I’m shooting at small reactive targets like clay pigeons at 50 yards, I can easily spot my hits. I’ve found the rimfire MOA reticle particularly useful – it’s fine enough for precise aiming but bold enough that I don’t lose it in low light or against dark targets.
I have noticed some edge distortion at 9x magnification when I’m scanning for targets. While the center 85% of the field of view stays crystal clear, there’s a noticeable blur around the edges. This hasn’t really affected my shooting since I’m typically focused on the center portion anyway.
Magnification & Parallax
The 3-9x magnification range works perfectly for my M&P 15-22. At 3x, I can quickly engage multiple targets at 25 yards, and the 9x gives me enough magnification to work steel targets out to 100 yards. The zoom ring has just the right amount of resistance – I can adjust it easily but it won’t move accidentally when I’m moving around.
The fixed 60-yard parallax has been a mixed experience in my testing. For most of my shooting between 40-80 yards, I don’t notice any issues. However, when I’m shooting closer targets around 25 yards, I have to be more careful with my head position to avoid parallax error, especially at higher magnification.
Elevation & Windage Knobs
I really appreciate the positive clicks from these turrets – each 1/4 MOA adjustment gives me both tactile and audible feedback. During my initial sight-in, I found the clicks track true to value, making precise adjustments straightforward. The turret caps thread on securely, though I’ve learned to check their tightness after transport.
Zero retention has exceeded my expectations. I’ve removed and remounted this scope several times for cleaning, and it returns to zero every time. I’ve got enough adjustment range to zero easily at 50 yards and still make holdover corrections out to 100 yards, though I did find myself wishing for slightly more elevation adjustment at longer ranges.
Eye Relief & Eye Box
The 3.7-4.2 inch eye relief works great with my M&P 15-22’s AR-style stock. I mounted the scope using medium-height rings, which gives me a comfortable head position. I’ve found the eye box quite forgiving at lower magnifications – even if my cheek weld isn’t perfect, I can still maintain a full sight picture.
At 9x magnification, the eye box does get more critical. I’ve learned to maintain a more consistent cheek weld for higher-power shots, but once I found the sweet spot, it’s been consistent and comfortable even during longer shooting sessions.
Durability
Over six months of regular use, I’ve put this scope through quite a bit. It’s been bounced around in my range bag, exposed to light rain during outdoor sessions, and dealt with temperature swings from chilly mornings to hot afternoons. I’m particularly impressed that it’s never shown any internal fogging, even on humid days when my other optics struggled.
The finish has held up well to regular use, though I’ve noticed some minor wear marks around the turret caps from frequent adjustments. I’ve found the scope maintains its crisp adjustment feel and smooth zoom operation even after exposure to the carbon fouling that rimfire ammo tends to generate.

2. Best Value: Vortex Crossfire II 2-7×32 Rimfire
When I first mounted this scope on my M&P 15-22, I was initially concerned about the lower magnification range, but after four months of regular use, I’ve come to appreciate its versatility. I’ve run about 800 rounds through various drills and casual shooting sessions, and I’ve been consistently impressed by how well it handles rapid target transitions. The smaller 32mm objective lens did make me wonder about light gathering, but in practice, it’s proven more than adequate for most daylight shooting.

I tested with Federal bulk pack and CCI Mini-Mags, five 5-shot groups each distance
Glass Clarity & Reticle
What’s surprised me most about this scope is how bright the image appears despite the smaller 32mm objective. During my afternoon shooting sessions, I’ve found the glass provides excellent contrast – black targets stand out clearly against light backgrounds, and I can easily spot my .22 impacts on steel. The V-Plex reticle isn’t fancy, but I’ve grown to appreciate its simplicity during rapid-fire drills.
I have noticed that the image gets a bit soft around the edges at 7x, though this hasn’t affected my shooting since I naturally focus on the center. My biggest complaint would be the relatively thick reticle wires – they can obscure small targets at longer ranges.
Magnification & Parallax
Initially, I was skeptical about the 2-7x range, but it’s proven ideal for the M&P 15-22. The 2x setting gives me an incredibly wide field of view – perfect for shooting reactive targets at close range. Even at 7x, I can consistently hit 1-inch targets at 50 yards. The adjustable parallax is a standout feature; I’ve found it particularly useful when shooting from unconventional positions during practice sessions.
The zoom ring has just enough resistance that I won’t accidentally bump it, but it’s smooth enough that I can adjust it without taking my eye off target. My only gripe is that the magnification numbers can be hard to read in low light.
Elevation & Windage Knobs
These turrets have been a pleasant surprise – each click is distinct and audible, which I really appreciate when making quick adjustments. During my initial sight-in, I found the 1/4 MOA clicks track true, making it easy to dial in my zero. The caps thread on securely, though I wish they were tethered – I’ve almost lost them a couple times in tall grass.
Zero retention has been rock solid through four months of regular use. I’ve bumped the rifle against doorframes and dropped it (accidentally) in my truck bed, but the scope maintains its zero. The turrets provide enough adjustment range for any reasonable rimfire shooting distance.
Eye Relief & Eye Box
The 3.9-inch eye relief works perfectly with my M&P 15-22’s AR-style stock. I’m particularly impressed by how forgiving the eye box is at 2x – even with imperfect head position, I can maintain a full sight picture. This has made transitioning between targets much faster than I expected.
At 7x, the eye box does get more critical, but it’s still manageable. I’ve found that proper cheek weld becomes more important at higher magnifications, though not to the point where it’s frustrating.
Durability
I’ve subjected this scope to plenty of real-world abuse over the past few months. It’s been rained on during an unexpected shower, bounced around in my range bag, and exposed to temperature swings from 40°F to 85°F. Through it all, the scope has maintained its zero and clarity.
The matte finish has held up well, showing only minor wear at contact points. I particularly appreciate how well the scope has handled the frequent cleaning needed with rimfire ammunition – no signs of finish wear around the turret caps or zoom ring.

Testing done with CCI Mini-Mags and Federal Premium Hunter Match, five 5-shot groups each
Glass Clarity & Reticle
The glass quality has impressed me throughout my testing. I can easily spot .22 LR impacts on paper at 50 yards, and the contrast makes black bullseyes stand out clearly against white targets. The DZ22 BDC reticle has proven to be a standout feature – I’ve found its holdover points align perfectly with CCI Mini-Mags out to 100 yards, though you’ll need to verify the drops with your specific ammunition.
In bright conditions, the scope performs admirably, though I have noticed some chromatic aberration when shooting against bright backgrounds or during sunset. The reticle stays visible in most lighting conditions, but can get a bit hard to see in deep shade.
Magnification & Parallax
The 3-9x range suits my needs with the M&P 15-22 well. At 3x, I have a good field of view for close-range plinking, while 9x gives me enough magnification for precision work at longer ranges. During one recent range session, I particularly appreciated the smooth magnification adjustment when transitioning between 25-yard paper targets and 100-yard steel plates.
This scope’s most unique characteristic is its 100-yard fixed parallax. While it works perfectly for longer-range shots, I’ve had to adapt my technique for closer targets. At distances under 50 yards, I’ve learned to be extra careful with my head position to maintain accuracy. The sweet spot seems to be between 75 and 125 yards, where parallax effects are minimal.
Elevation & Windage Knobs
The turrets on this scope provide positive clicks that I can feel even while wearing light gloves. Each 1/4 MOA adjustment tracks consistently, making sight-in sessions straightforward. I particularly appreciate how well the turret caps seal against moisture – I’ve had no issues even after shooting in light rain.
Zero retention has been excellent over several months of use. The scope returns reliably to zero after making temporary adjustments for different distances. My only complaint is that the clicks could be a bit more audible in noisy environments – I sometimes find myself counting by feel rather than sound.
Eye Relief & Eye Box
With 3.6 inches of eye relief, I had to mount this scope slightly differently than other optics to maintain a proper sight picture with my M&P 15-22’s AR-style stock. The eye box is relatively forgiving at 3x, but gets quite tight at 9x. After several range sessions, I’ve learned to maintain a very consistent cheek weld, especially when shooting at maximum magnification.
One advantage I’ve found is that the shorter eye relief allows for a more forward mounting position, which helps balance the rifle better despite the scope’s heavier weight. However, this does require some practice to maintain proper head position consistently.
Durability
Throughout my testing period, this scope has proven remarkably robust. It’s maintained zero despite numerous range trips and regular transport in my range bag. The finish has resisted scratching well, though I did notice some wear around the turret caps after frequent adjustments.
The scope has handled temperature changes from early morning to mid-afternoon sessions without any internal fogging. I’ve been particularly impressed with how well it’s resisted the carbon fouling that rimfire ammunition tends to generate – regular cleaning keeps everything moving smoothly.

4. Best Budget: Simmons 3-9x32mm .22 Mag
When I first picked up my M&P 15-22, this Simmons scope was my initial optic choice due to its budget-friendly price point. Over three months of regular use, putting about 600 rounds downrange, I’ve gotten a clear picture of what this scope can and can’t do. While it’s definitely built to a price point, I’ve found some surprising capabilities alongside the expected limitations.

Glass Clarity & Reticle
For its price point, the glass clarity surprised me in good lighting. During bright daylight hours, target identification is clear enough for casual plinking at common rimfire distances. The Truplex reticle is basic but functional – the thick outer posts help draw your eye to center quickly, while the finer center section allows for reasonable precision.
However, limitations become apparent in challenging light conditions. I’ve found the scope struggles during overcast days and early morning sessions. The image gets noticeably darker as the sun starts setting, which significantly limits useful shooting time compared to more expensive optics.
Magnification & Parallax
The 3-9x magnification range works adequately for most rimfire distances. During testing, I typically kept it around 3-4x for general plinking and bumped it up to 6x for more precise shots at 50 yards. Beyond that, I noticed significant image quality degradation. The zoom ring moved smoothly enough after a break-in period, though it was quite stiff initially.
The fixed 50-yard parallax makes sense for rimfire use. I’ve found it provides acceptable performance from 25 to 75 yards, though head position becomes increasingly critical at closer distances. The focus stays sharp enough for casual shooting, but precision work requires careful attention to technique.
Elevation & Windage Knobs
The turret adjustments reveal the scope’s budget nature most clearly. The clicks aren’t very distinct – I often found myself counting adjustments by feel rather than sound. Each 1/4 MOA adjustment does track consistently once you get used to the mushy feel. The turret caps are basic but functional, though I’ve learned to check their tightness regularly.
Zero retention has been acceptable if not outstanding. The scope holds zero well enough for casual shooting, though I do verify zero if the rifle has been bounced around in transport. The adjustment range proves adequate for typical rimfire distances, even if making precise adjustments takes some practice.
Eye Relief & Eye Box
The 4-inch eye relief stands out as one of this scope’s best features. It works particularly well with the M&P 15-22’s AR-style stock, and I’ve had no issues maintaining a full sight picture. The eye box proves surprisingly forgiving at lower magnifications, making it especially beginner-friendly.
At 9x magnification, the eye box does tighten up considerably. Through my testing, I’ve learned to maintain a more consistent cheek weld for higher-power shots. However, it’s still more forgiving than I expected at this price point once you find the sweet spot.
Durability
During my three-month testing period, the scope has handled basic range use adequately. It’s survived a few light rain showers and regular transport in my range bag without issues. The lightweight construction, while not confidence-inspiring, has proven sufficient for rimfire recoil.
The finish shows wear more quickly than premium scopes – I’ve noticed some marks around the turret caps and rings after just a few months. The scope has resisted internal fogging during my testing, though I haven’t subjected it to extreme temperature changes.

How to Choose the Best Scope for M&P 15-22 Buyer’s Guide
Through my experience with various scopes on the M&P 15-22 platform, I’ve learned that choosing the right optic involves understanding both the rifle’s capabilities and your intended use. Unlike centerfire AR-15s, the M&P 15-22’s minimal recoil and rimfire ballistics create unique considerations for scope selection.
Understanding M&P 15-22’s Unique Requirements
The M&P 15-22’s AR-style platform brings specific characteristics that affect optics selection:
- AR-height mounting needs affect eye relief requirements
- Minimal recoil allows for lighter mount options
- Rimfire trajectory benefits from specific reticle designs
- Common shooting distances influence parallax settings
Key Selection Factors
1. Optical Quality
While the M&P 15-22 doesn’t demand the highest-end glass, decent optical quality makes a noticeable difference in shooting enjoyment. From my testing, these aspects matter most:
- Clear center image for precise rimfire shooting
- Good light transmission for indoor range use
- Adequate edge clarity for quick target acquisition
- Reticle visibility in varying light conditions
2. Magnification Range
Based on my range sessions, most M&P 15-22 shooting happens between 25 and 75 yards. Consider these magnification guidelines:
- 2-7x works great for quick shooting and plinking
- 3-9x offers good all-around versatility
- Fixed power can work well for specific uses
- Higher magnification rarely needed beyond 100 yards
3. Parallax Consideration
Different scopes handle parallax differently for rimfire use:
- Adjustable parallax offers most versatility
- 50-yard fixed works well for general use
- 60-yard fixed better for longer range focus
- 100-yard fixed requires technique for close shots
4. Mounting Considerations
The M&P 15-22’s AR-style platform requires specific mounting attention:
- Medium-height rings typically work best
- One-piece mounts offer good stability
- Thread-lock recommended on all mounting screws
- Consider weight distribution on lightweight rifle
Frequently Asked Questions
What magnification range do I really need for the M&P 15-22?
From my experience, a 3-9x range covers most shooting scenarios perfectly. I find myself using 3-4x for quick plinking and close range work, while 6-9x works well for precision shooting out to 100 yards. Higher magnification rarely provides additional benefit with .22LR ballistics.
Do I need adjustable parallax for rimfire shooting?
While not essential, I’ve found adjustable parallax helpful when switching between close plinking and longer range shots. Fixed parallax at 50 or 60 yards works fine for general use, but adjustable parallax makes precision shooting easier, especially at varying distances.
What’s the best mounting height for an M&P 15-22 scope?
I typically use medium-height rings with most scopes on my M&P 15-22. This height provides good alignment with the AR-style stock while maintaining comfortable cheek weld. Low rings can work but often require an awkward head position with the AR-style stock.
