ATI Outdoors Carbine-Length Gas Tube, Black Nitride Steel

The ATI Outdoors Carbine-Length Gas Tube in Black Nitride Steel (brand part no. A.5.10.2550) carries gas from a low-profile gas block back to the AR-15’s bolt carrier group, a critical link in the rifle’s cycling that a bent or corroded factory tube can compromise. ATI Outdoors finishes this tube with a black nitride coating for corrosion resistance and heat tolerance beyond a bare steel finish, giving builders a durable replacement or upgrade part. Sized to the carbine gas system length, it’s built to work with low-profile gas blocks common on modern AR-15 handguard setups. This is a straightforward, functional upgrade for anyone building a fresh upper or replacing a damaged gas tube.
