LBE Unlimited Low-Profile Gas Block with Mid-Length Gas Tube – AR-15

The LBE Unlimited Low-Profile Gas Block with Mid-Length Gas Tube is a direct replacement for standard AR-15 gas systems, designed to sit beneath free-float handguards without interference. This gas block captures propellant gases from the barrel and redirects them through the included mid-length tube to cycle the bolt carrier group. Upgrading to a low-profile design allows shooters to install modern handguards that extend over the gas system for improved ergonomics and accessory mounting space.

Constructed from steel with a matte black finish, this gas block is machined to fit standard .750-inch diameter barrels. Installation requires removal of the existing gas block and tube, alignment of the gas port, and secure fastening with set screws. Basic armorer-level experience and proper tools are recommended for installation. The included mid-length gas tube is cut to the correct length for mid-length gas systems (approximately 11.75 inches from receiver to gas block).
