Enhance your rail system with our ultra-low-profile gas blocks, perfect for pairing with Faxon Firearms (or any other) barrels featuring a standard diameter gas journal. Crafted from high-strength steel, our gas blocks match the sleek black luster of our barrels seamlessly. Designed for lightweight builds, these gas blocks feature a drilled-through middle profile. They securely clamp onto the barrel using three Allen keys located on the underside of the block. For optimal performance, Faxon Firearms recommends the use of Loc-Tite or similar thread-locking compounds to ensure a secure fit. It's important to note that gas blocks can reach high temperatures during use, so selecting an appropriate compound is crucial based on your firearm's intended application.
