The standard gas system of the AR-15 platform poses a problem when installing handguards or rail system that extend past the barrel's gas port. If you're looking to install a long handguard or a rail system and need a low-profile replacement for the factory gas block, Fortis Manufacturing has the answer.

The Fortis Low-Profile Gas Block is machined from rugged 4140 steel to provide the enduring reliability that customers expect from Fortis. The block is short enough to accommodate a handguard of any length you choose. It is fixed to the barrel with two set screws, so you don't have to be concerned about scuffing and scraping your barrel during installation! The slick, streamlined design is an interesting break from the ordinary as well.

The Fortis .750 Low Profile Gas Block comes in: Black and Stainless Steel finish.
