Description
The Smith & Wesson S&W M&P15-22, .22LR, Performance Center, Threaded Barrel is a purpose-built, high-performance rimfire AR-platform rifle. It’s designed from the ground up for .22LR, featuring a lightweight polymer receiver set, a match-grade threaded barrel, and enhanced Performance Center trigger for serious training and high-volume plinking. I’ve put thousands of rounds through this platform, and it’s the most reliable .22LR AR-pattern rifle I’ve used—no gunsmithing required to get it running right out of the box.
Key Features
- Performance Center Enhanced Trigger: A smoother, lighter pull for better accuracy.
- Threaded 16.5″ Barrel: Ready for a suppressor or muzzle device (thread protector included).
- Lightweight Polymer Construction: Reduces overall weight to just 5.9 lbs unloaded.
- Dedicated .22LR Design: Not a conversion kit; optimized for rimfire reliability.

Look, the specs tell part of the story, but the real magic is in the handling. The 16.5-inch barrel gives you that classic rifle feel without being unwieldy, and the 1/2″-28 threading is the standard for .22LR cans. At $580.35, you’re getting a tool that bridges the gap between a cheap plinker and a serious training asset. It ships to Missouri and compliant US states, ready for your FFL. The controls are where it shines—the magazine release, bolt catch, and safety are all where your muscle memory expects them to be if you’re used to an AR-15. That said, the polymer upper and lower keep it light, which is a blessing when you’re carrying it all afternoon or introducing a new shooter to the platform.
Who This Rifle Is For
This is for the shooter who wants affordable, high-volume trigger time with the ergonomics of their duty or home defense rifle. It’s perfect for Missouri hunters looking for a small-game getter, parents teaching fundamentals to new shooters, or anyone wanting to practice drills without the cost and recoil of 5.56. It’s also a fantastic host for a .22 suppressor—quiet, fun, and cheap to feed.
Pros & Cons
Pros: Incredibly low-cost training. The Performance Center trigger is a tangible upgrade over the standard model. Eats all types of .22LR ammo I’ve tried. Works with many standard AR-15 accessories—I’ve used Magpul MOE grips and stocks on mine without issue. Easy to clean and maintain.
Cons: The polymer construction feels different than aluminum—some purists don’t like it. The proprietary magazine is the only real option, but it’s a good one. You’ll need to buy more ammo because you’ll shoot it so much.
Frequently Asked Questions
Q: Is this just a standard AR-15 chambered in .22LR?
A: No, and that’s key. It’s a dedicated .22LR platform. The bolt, barrel, and magazines are designed specifically for rimfire, which leads to far greater reliability than most drop-in conversion kits. The upper and lower are also polymer to save weight and cost.
Q: What accessories are compatible?
A: It uses a standard Mil-Spec diameter buffer tube, so most AR-15 stocks and pistol grips fit. The handguard has a standard Picatinny top rail and uses a common barrel nut, allowing for aftermarket M-LOK or KeyMod replacements. Optics, lights, and slings mount just like on a centerfire AR.
Q: Can it cycle subsonic ammunition?
A: With its straight blowback action, it generally cycles standard and high-velocity rounds best. Some subsonic ammo may not have enough energy to reliably cycle the bolt, especially unsuppressed. For suppressed use, stick to high-velocity or specific “suppressor” rated .22LR rounds for guaranteed function.
If you’re looking for a .22 that feels like your AR but won’t break the bank on ammo, the M&P15-22 Performance Center model is the one to get. See the full details and check availability at firearms-missouri.com for Missouri residents and nationwide.
