The 16-inch barrel is clearly marked "5.56 NATO 1/8 5R," combining a 1:8 twist with 5R rifling. A low-profile gas block keeps the sight line clean and works with the free-float handguard for accessory mounting without contacting the barrel.
Smith & Wesson’s free-float quad-rail handguard is branded with "MILITARY & POLICE." The rifle is equipped with a 6-position M4-type collapsible stock in polymer and an A2-type pistol grip. Length of pull measures 13.25 inches. Controls include a standard right-side magazine release and a manual safety.
Flip-up polymer front and rear sights are installed, along with an angled polymer foregrip. A receiver end-plate sling loop is in place for simple sling attachment.
Capacity is 20+1 with the included 20-round USGI-pattern magazine. The rifle retains full-length top rail space and the free-float quad-rail for mounting compatible accessories as needed.
