LBE Unlimited ARLPGB Low Profile Gas Block .750" Black Nitride 4142 Steel AR-15

The LBE Unlimited ARLPGB is a low profile gas block purpose-built as a direct-fit replacement or upgrade for AR-15 pattern rifles. Machined from 4142 steel and finished in a durable black nitride coating, the ARLPGB features a .750" inside diameter sized to clamp securely over a standard barrel gas block journal. Its low profile silhouette sits cleanly under most free-float and drop-in handguards, making it ideal for handguard swaps, barrel replacements, and custom AR-15 builds where a tall A2 front sight base is no longer needed.

Installation is straightforward: the ARLPGB ships with the set screws and gas tube roll pin needed to secure the block to the barrel and lock in a standard gas tube. Made in the USA by LBE Unlimited, the ARLPGB delivers reliable, repeatable gas system performance at an excellent value for AR-15 builders, gunsmiths, and armorer-level maintenance.
