Dark Hour Defense AR15 .750 Gas Block

The Dark Hour Defense Nitro Express Nitro Gas Block is a simple yet elegant solution to a common problem in the AR15 platform, Gas Leaks. The Nitro Gas Block fills the common .750 Nitro express gas block size and relieves the pressure on the gas tube caused by excessive gas expansion while under fire. Dark Hour Defense Nitro Gas Blocks are the perfect way to return your Nitro Express rifle to stock or to build your custom upper. A common problem seen with the .750 Nitro express gas block is the underside or “dog bone” on the gas block. This creates pressure spikes and excess heat in the system that can damage upper receivers, gas tubes and gas seals. Machined from a 4140 alloy this gas block will last you a long time. Complete with two screws and fastened with self-tapping screws you will never have to worry about stripping or leaking.
