Product Details
This heavy-profile barrel is built for 300 Blackout loads, which means it handles both standard and subsonic ammunition without fussing around. At 10.5 inches with a pistol-length gas system, it's compact enough for a short-barreled rifle while staying reliable - great if you're building something handy but still powerful. It's made from quality 4150 steel with a nitride finish that'll hold up to regular use, and it threads on to any standard AR15 platform, so if you've already got the receiver, this gets you most of the way there.
