LBE Unlimited Low Profile Gas Block Features The LBE Unlimited Low Profile Gas Block is machined from stainless steel and finished with a black nitride coating that resists corrosion and wear far better than a standard phosphate finish. Its low profile design keeps the block compact enough to sit beneath most modern free-float handguards which is essential for builders running a clean obstruction-free rail for accessories and optics. Built to fit .750 inch barrels this gas block covers one of the most common gas journal diameters found on AR-pattern rifles and pistols. The nitride finish also improves surface hardness helping the block resist galling and wear at the barrel interface over years of use. This gas block ships with a pistol length gas tube already installed made from seamless 304 stainless steel tubing for reliable gas transfer and resistance to corrosion. Pairing a low profile gas block with a pistol length gas system is a common configuration for short-barreled AR pistols and SBRs where handguard length and gas port timing are critical to reliable function. LBE Unlimited designs and builds every component domestically in the United States backing this gas block with the same quality control the company applies across its full line of AR parts. For builders assembling a pistol length AR upper the LBE Unlimited Low Profile Gas Block offers a durable ready-to-install solution.
