These ultra-low profile gas blocks are compatible with any rail system and ideal for Faxon Firearms barrels or other barrels with a standard diameter gas journal.
Made from high-strength steel, the blocks match Faxon barrels in black luster and are designed with a drilled-through lightweight build, secured with 3 allen keys.
Faxon Firearms recommends using thread-locking compounds like Loc-Tite for these gas blocks due to the high temperatures they will reach during use.
