All the AR-15 handling you rely on, at a fraction of the operating cost. The Smith & Wesson M&P15-22 Sport B5 .22 LR 16.5″ brings .22 LR economics to a genuinely familiar platform for training, plinking, and recreational use.

A semi-automatic AR-15 rifle chambered in .22 LR, the Smith & Wesson M&P15-22 Sport B5 .22 LR 16.5″ combines direct impingement operation with standard AR-15 architecture for straightforward reliability.

Cost-Effective Proficiency: Shooting .22 LR means you can practice three times as long for the same ammunition budget. Consistent practice is the single biggest driver of shooting improvement.

Familiar Handling: Weight, balance, and control layout closely mirror full-caliber AR-15 configurations — your grip, stance, and trigger technique all carry over directly.

Accessible for New Shooters: Low recoil and low noise make this an approachable starting point for new shooters, younger family members, or anyone working to overcome a flinch.

Small Game Ready: Accurate at reasonable distances and with enough energy for pest control and small game, this platform pulls double duty beyond just range training.

Accepts standard AR-15 lower receivers with a dedicated .22 LR BCG and caliber-specific magazines. Makes an ideal affordable training counterpart to a centerfire AR-15 setup.

The upper and lower receivers are constructed from 7075 aluminum with a Type III Hardcoat Anodized finish — a durable combination that resists corrosion and maintains tight tolerances over an extended service life.

Ideal for training on fundamentals without centerfire costs — trigger control, sight picture, and magazine manipulation all transfer directly to larger-caliber AR-15 platforms.

Smith and Wesson has been producing American firearms for over 170 years. The M&P15 series is backed by S&W’s lifetime service policy and a track record of reliable performance in the field. Made in the USA.
