The M&P 15 Sport III is the latest evolution of Smith & Wesson’s proven Sport series — upgraded where it matters while keeping it lightweight, reliable, and ready to run.
Built around a 16” 4140 steel barrel with Armornite finish, this rifle features 5R rifling with a 1:8 twist, giving you excellent accuracy and the flexibility to run a wide range of ammo. The upgraded mid-length gas system helps reduce recoil and improves overall shooting performance.
Up front, you get a 15” free-float M-LOK handguard, giving you plenty of room for optics, lights, and accessories. Paired with a full-length Picatinny rail, this platform is ready to be customized exactly how you want it.
Finished with a 6-position adjustable stock, A2 flash hider, forward assist, and dust cover, the Sport III delivers serious value whether it’s your first AR or your next addition.
