Aero Precision .936 Low Profile Gas Block – Aero Logo – Nitride
Tame your gas system with durable, low-profile precision—built to last.
The Aero Precision .936 Low Profile Gas Block is engineered for large-diameter AR barrels and precision shooters who demand reliable gas delivery and seamless handguard compatibility. Machined from 4150 chrome-moly steel and finished with a salt-bath nitride coating, this gas block resists corrosion and abrasion for extended durability in any shooting condition.
Its .936” gas seat diameter makes it ideal for heavy-profile barrels, while the low-profile design ensures compatibility with nearly all free float handguards. Includes dual steel set screws (10-32 x 3/16 knurled cup point) for secure installation and proper alignment with dimpled barrels.
Whether you’re upgrading a match rifle or building a custom AR-10/AR-15, this American-made gas block provides rock-solid performance without compromise.
Note: Roll pin not included. Use only a non-permanent thread locker—Aero does not recommend a red thread locker for set screws.
