Faxon Firearms Low Profile Gas Block .750" 3-Screw 4150 Steel

The Faxon Firearms Low Profile Gas Block is an ultra-low-profile fixed gas block designed for AR-platform rifles. Machined from 4150 steel for serious duty use, it clamps securely to barrels with a .750" diameter gas journal using three set screws, giving a clean, snag-free profile that fits under virtually any rail system or free-float handguard.

Faxon's ultra-low-profile gas block is the ideal companion for any barrel with a standard .750" gas journal, including Faxon Firearms barrels and other quality AR-pattern barrels. Its compact form factor keeps the front end of your build light and uncluttered, making it well suited for both duty and competition rifles. The block measures 1.00" wide by approximately 1-7/32" tall and weighs just 0.07 lbs.

Installation is straightforward: the 3-screw design mounts to the barrel's gas journal with an Allen key, and the package includes gas tube roll pins for pinning your gas tube once the block is torqued to spec. With its 4150 steel construction and Faxon's reputation for precision-machined components, this gas block delivers a tight, repeatable gas seal without adding bulk to your build.
