The Sport II Optics Ready configuration provides a flat-top upper with a T-marked Picatinny rail for mounting optics, and ships without factory sights. A squared, pinned gas block adds a short Picatinny rail and a fixed front sling loop, complementing the carbine-length gas system and direct-impingement action.
The 16-inch barrel is made from 4140 CM steel and uses a 1:9 twist to stabilize a wide range of 5.56 NATO ammunition. It is threaded 1/2x28 TPI and fitted with a standard A2-pattern flash hider, offering ready compatibility with common 1/2x28 muzzle devices.
Receivers are 7075-T6 aluminum with a hard-coat anodized black finish and include a forward assist, ejection-port dust cover, and case deflector. The rifle uses a standard charging handle and manual safety for familiar, reliable controls.
Furniture includes a two-piece ribbed polymer handguard (carbine length), an A2-style polymer pistol grip, and a 6-position collapsible stock with a sling loop. The STANAG magazine interface provides a 30+1 capacity and broad magazine compatibility; one Magpul PMAG GEN M3 is included.
Overall length is approximately 32–35 inches with an unloaded weight around 6.7 lb, keeping the rifle nimble while maintaining stability. This U.S.-made example arrives in excellent condition, with the original Smith & Wesson case and manual.
