Luth-AR BL-04C AR-15 Mid Length Gas Tube 304 Stainless Steel 11.75"

The Luth-AR BL-04C Mid Length Gas Tube is a replacement gas tube for mid-length AR-15 gas systems, manufactured from 304 stainless steel to an overall length of 11-3/4" and heat-treated to Army specification standards.

Designed as a direct replacement for the standard mid-length AR-15 gas tube, the BL-04C suits both new-build assembly and field replacement of a worn factory tube. Luth-AR offers matching carbine-length and rifle-length versions of the same 304 stainless tube for builders running different gas-system lengths across an upper fleet.

Installation is straightforward: the tube drops into the standard AR-15 upper-receiver gas-channel passage and is secured with a gas-tube roll pin (sold separately).

Sold as a single gas tube.
