LBE Unlimited ARLGBP Low Profile .750" Gas Block with Pistol Length Gas Tube - Black Nitride Steel

The LBE Unlimited ARLGBP is a low-profile .750" gas block built for AR-15 pistol-length builds, engineered to keep your upper receiver profile minimal while maintaining reliable gas cycling. If you're running a short-barreled AR pistol or SBR and want a gas block that stays out of the way without sacrificing function, this one does the job. It ships with a pistol-length gas tube pre-installed, so you get a complete, matched gas system ready to mount.

The black nitride steel finish delivers proven corrosion resistance and durability across extended shooting sessions. Nitride coatings outperform basic finishes when it comes to fouling resistance and holding up under heavy use—shooters rely on them for a reason. The included gas tube is seamless 304 stainless steel, a material choice that matters because it eliminates weak points and ensures consistent function over time.

LBE Unlimited manufactures this block in the USA, so you're getting American-made quality built to work. Whether you're assembling a dedicated pistol upper, a suppressed short-barrel rifle, or any AR platform running pistol-length gas, this low-profile block and tube combination simplifies assembly and eliminates the need to source compatible components separately.
