Smith & Wesson’s Sport II series adds a forward assist and dust cover to the classic M&P-15, delivering the features shooters expect in a modern AR-15. This rifle’s TS-prefix serial indicates current-production Sport II standards.
The 16-inch 4140 CMV barrel uses a 1:8 twist to stabilize common 55- to 77-grain bullets. Armornite treatment guards against corrosion, and the 1/2-28 threads host a stainless three-port brake that helps tame muzzle rise.
An ERGO 15-inch M-LOK handguard replaces the stock unit, providing a rigid free-floating interface that can accept lights, bipods, or other accessories without affecting barrel harmonics. Its slim aluminum profile keeps weight in check while maximizing cooling.
The upgraded charging handle features a skeletonized extended latch, giving the shooter easier access under optics or with gloved hands. A six-position polymer stock with QD sling recess offers quick length-of-pull adjustments.
