The S&W M&P15-22 Sport MOE SL 22 LR 16.5 in 25+1 Rd is a rimfire modern sporting rifle that mirrors the feel of a centerfire AR, but in an affordable, low-recoil .22 LR package. Built with a lightweight polymer receiver and Magpul MOE SL furniture, it’s perfect for training new shooters, plinking with the family, or getting in cheap practice without burning expensive ammo. This rifle ships with a 25+1 round magazine, a 16.5-inch carbon steel barrel with Armornite finish, and Magpul MBUS flip-up sights right out of the box.

Key Features
- Magpul MOE SL Furniture: The slim-profile handguard and stock reduce weight and improve grip for smaller hands — why it matters: youth shooters and beginners can handle this rifle comfortably at the range all day.
- Threaded Muzzle with Flash Suppressor: The 16.5-inch barrel comes threaded (1/2×28) with a factory-installed flash hider — why it matters: you can easily add a suppressor or muzzle brake for quieter training or reduced recoil.
- Magpul MBUS Flip-Up Sights: Front and rear sights are included and fold flat when not needed — why it matters: no need to buy extra iron sights; you’re ready to shoot right out of the box.
- AR-Style Controls and Ergonomics: Identical safety selector, charging handle, and magazine release as a centerfire AR — why it matters: training on this .22 LR builds muscle memory that transfers directly to your 5.56 rifle.
- 25+1 Round Capacity: Comes with one 25-round magazine (plus one in the chamber) — why it matters: more shots between reloads means more time focusing on fundamentals.
Who It’s For
This rifle is built for families who want to introduce new shooters to the AR platform without the noise and recoil of a centerfire. It’s also ideal for youth shooters who need a lightweight, easy-to-manage rifle for competition or plinking, and for beginners who want an affordable way to practice marksmanship and gun handling. If you’re a seasoned shooter looking for a cheap training companion to your duty AR, this fits that role perfectly.
Pros / Cons
- Pro: Extremely reliable with standard-velocity .22 LR ammo — feeds, fires, and ejects consistently.
- Pro: Lightweight at 4.65 lbs, so even young shooters can hold it steady for extended sessions.
- Pro: Full-length Picatinny top rail allows easy mounting of optics or a red dot.
- Con: The polymer receiver can feel less sturdy than aluminum — but that’s also what keeps the weight down and cost low.

FAQ
What magazines does the S&W M&P15-22 Sport MOE SL use?
It uses standard Smith & Wesson M&P15-22 magazines. The included magazine holds 25 rounds. Black Dog Machine also makes aftermarket options that work with this rifle.
Is this rifle compatible with standard AR-15 parts?
The lower receiver is polymer and not compatible with standard AR-15 buffer tubes or triggers. However, the upper uses a standard AR-15 barrel nut and handguard mounting system, so you can swap handguards. The stock is also AR-15 compatible (mil-spec buffer tube size).
Can I mount a suppressor on the S&W M&P15-22?
Yes, the 16.5-inch barrel is threaded 1/2×28 and comes with a flash suppressor. Remove the flash hider and thread on a .22 LR-rated suppressor. Note: always verify local laws before adding a suppressor.
What kind of accuracy can I expect?
With quality .22 LR ammunition, expect 1.5–2 inch groups at 50 yards. It’s not a precision benchrest rifle, but it’s more than accurate enough for plinking, small game, and training drills.
Does this rifle come with a case or tools?
It ships in a cardboard box with the rifle, one 25-round magazine, and a cable lock. No hard case or cleaning tools are included.
