Looking to free float your barrel and upgrade your AR-15? The Aero Precision low profile gas block is the perfect solution. With its low-profile design, it will fit under almost any free float handguard on the market. These American-made gas blocks are machined from hardened 4150 chrome moly steel with a tough phosphate finish. They include a set of steel 10-32 x 3/16 knurled cup point set screws for securely attaching them to your barrel. With precise machining tolerances, you can expect a perfect match to your barrel with .875” gas block journal and compatibility with all rifle and carbine length gas tubes.
NOTE: Aero Precision does not recommend the use of red thread locker on the set screws. If you decide to use thread locker, they recommend using a non-permanent variety.
