The RW Arms AR-15 Gas Block – .750″ Low Profile is available as an Adjustable or Non-Adjustable block. It is machined from durable steel with a tough manganese phosphate finish. The low profile design easily fits under the majority of free float handguards and securely installs to barrels with a standard .750″ diameter gas seat via the secure dual set screws. Add in some aesthetic edging and you’ve got a fantastic choice for your next build.
The AR-15 Adjustable Gas Block is a part of the gas system that replaces the standard front sight base. On the AR, there is a small “gas port” (small hole) in the barrel that vents gas with every shot. This gas travels through the gas block and gas tube into the receiver, where it powers the bolt carrier group and auto-cycles the next round.
