Barrel and Twist Rate

The M&P 15 Sport II features a 16‑inch barrel, a length favored for balancing velocity, accuracy, and maneuverability. The barrel is typically made from durable steel and treated for longevity.

This setup supports consistent accuracy without locking the shooter into a narrow ammunition profile.

Sights and Optics Readiness

From the factory, the rifle comes equipped with a fixed front sight and a detachable rear sight.

The flat‑top upper receiver includes a Picatinny rail, making it easy to mount red dots, scopes, or magnifiers.
