Description
DSI 5.56 NATO 10.5" MTOP AR-15 Barrel
The DSI 10.5" 5.56 NATO SOCOM Barrel is manufactured in-house for compact AR-15 builds that need the durability of a medium taper profile without moving to a full-length barrel. Machined from 4143 chromoly steel, it combines a 1:7 twist with a carbine-length gas system and M4-style feed ramps.
The barrel features a .750-inch gas block journal, 1/2-28 threaded muzzle, and nitride heat-treated finish for durability and corrosion resistance. Its 10.5-inch length makes it well suited for AR pistol and Short Barrel Rifle configurations.
Proudly made in the USA.
