Overview
This low-profile gas block is designed for AR-15 builds that need a compact, unobtrusive fit under handguards while maintaining a clean setup. It is sized for .875" barrels and features the Aero logo with a phosphate finish, giving builders a straightforward option for a range of rifle configurations. Made from 4150 hardened steel and secured with steel 10-32 x 3/16 knurled cup point set screws, it is intended for practical assembly work rather than decorative use. A roll pin is not included, and Aero Precision notes that non-permanent thread locker is preferred if one is used.
