The Bravo Company LGB-750 is a purpose-built gas block designed for AR-platform rifles chambered in standard calibers with .750-diameter barrels. This is a no-nonsense component that handles the fundamental task of directing propellant gases to cycle your rifle's action.
Steel construction with a durable black phosphate finish provides reliable corrosion resistance and a professional appearance. The low-profile design minimizes obstruction of your sight picture and accessory mounting options on the upper receiver.
The block secures to your barrel using steel set screws (10-32 x 3/16 inch) with knurled cup points. This proven mounting method has been the standard in military and civilian AR rifles for decades. The set-screw design allows for straightforward installation and adjustment without specialized tools.
Designed for AR15, M16, M4, and M4A1 platforms with .750-inch barrel diameters. This is a straightforward, reliable component that does exactly what it's supposed to do.
