Black Rain LP936A .936 Adjustable Low Profile Gas Block

The Black Rain LP936A is an adjustable low profile gas block built for AR-pattern rifles and pistols chambered in larger calibers that use a .936" gas block journal. Designed and produced by Black Rain Ordnance, the LP936A delivers a clean, snag-free profile that tucks neatly under free-float handguards and rails while still allowing the shooter to fine-tune gas flow for reliable cycling with suppressed, short-barreled, or over-gassed setups.

The block carries a Black finish and is intended for barrels utilizing a .936" gas block journal. Its adjustable design lets you regulate the amount of gas reaching the bolt carrier group using a standard 5/64 hex wrench.

With its .936" inside diameter, the LP936A is intended for heavier-contour barrels commonly found on AR-10 / .308 Win / 7.62x51mm builds, and is equally at home on .300 Blackout, .223 Remington, and 5.56x45mm NATO pistol and rifle platforms that use the larger gas journal. Whether you are assembling an AR-10 precision rifle, a 7.62 pistol, or a .300 Blackout SBR, the Black Rain LP936A gives you a tunable, low-profile gas block in a compact package.
