Product Info for CMC Triggers AR-15 Tactical Short 5.56Nato Threaded AR Barrel w/Gas Block/Gas Tube

Step up to a carbine-length gas system and you get a softer, more even cycle. That's what this 11.5-inch barrel gives you. It sits in a nice middle spot: still short enough for tight quarters, long enough to pull solid velocity from 5.56 NATO. The 1:7 twist handles heavy bullets without trouble. Government profile, non-fluted, and finished in black nitride, so it shrugs off moisture. Muzzle threads are 1/2x28 TPI. Gas block and gas tube are included, which saves you a separate order and gets the build moving faster.image
