The Faxon Low Profile Gas Block (brand part number GB-LP-750-3) is a .750 inch diameter gas block machined from high-strength steel and finished in nitride for corrosion and wear resistance. Faxon builds it in a skeletonized Airlite design to shave weight without sacrificing strength, and secures it to the barrel with a three-set-screw system for a solid, low-profile hold under a free-float handguard. At just 0.07 lb, it adds almost nothing to your rifle’s balance. Made in the USA, it’s a durable, no-nonsense gas block for anyone building or upgrading a .750 inch barrel journal AR upper.
