Product Description

The Smith & Wesson M&P15 Sport III (10-Round Fixed Stock) is built for shooters in restrictive jurisdictions who still want the performance and features of a modern AR-15 platform. Its 16-inch barrel paired with a 1-in-8 R5 twist stabilizes a wide range of bullet weights, making it suitable for training, range use, and defensive applications.

A mid-length gas system provides smoother recoil impulse and improved reliability, while the free-floating 15-inch M-LOK handguard allows for mounting accessories such as lights, optics, and foregrips without affecting barrel harmonics. The hardcoat anodized black finish enhances durability and corrosion resistance for long-term use.

Equipped with a fixed CAR stock, integral trigger guard, and a 10-round PMAG, this rifle is compliant while remaining lightweight at just 6.4 lbs. It’s an excellent choice for shooters seeking a quality entry-level AR-15 with upgraded features right out of the box.
