Description
The Luth-AR BL-04A is a carbine length gas tube for the AR-15 platform. It carries propellant gas from the barrel's gas block to the bolt carrier group, cycling the action in a gas-operated semiautomatic rifle.
The tube is made from stainless steel and is sized for an AR-15 carbine length barrel. Matching the tube length to the barrel's gas system is what the part is intended to do, so confirm your barrel is carbine length before installing it.
The BL-04A is listed by Luth-AR under manufacturer part number BL-04A and is sold as a standalone replacement or upgrade gas tube.
