DSI 5.56 16” MTOP Carbine 1:9 Nitride Barrel

DSI 5.56 NATO 16" MTOP AR-15 Barrel

The DSI 16" 5.56 NATO MTOP Barrel is manufactured in-house for AR-15 builds and upgrades that benefit from a medium-taper barrel profile with a traditional carbine-length gas system. Machined from 4150 chrome moly vanadium steel, it features a 1:9 twist and M4-style feed ramps.

The medium-taper profile balances barrel rigidity and overall weight, while the carbine-length gas system provides compatibility with traditional AR-15 gas-system configurations. The barrel also features a .750-inch gas block journal, 1/2-28 threaded muzzle, and durable nitride finish.

Proudly made in the USA.
