LBE Unlimited ARRGB-UH .750 Railed Gas Block Upper Receiver Height AR-15 Black

The LBE Unlimited ARRGB-UH is a .750" railed gas block for the AR-15 platform, machined from aluminum with a black anodized finish and built to Mil-Spec dimensions.

Its defining feature is the integrated Picatinny rail set at upper receiver height, putting accessory optics, lights, or a flip-up front sight on the same sight plane as a flat-top upper without adding extra risers. The block fits standard .750" gas journals and clamps securely to the barrel with the three set screws included in the package, keeping the gas system reliably cycling during regular range use.

Sized for any AR-15 / M16-pattern rifle that uses a .750" gas journal, this railed gas block is a straightforward drop-in upgrade for builders and gunsmiths. Made in the USA by LBE Unlimited.
