A Low-Profile Gas Block Sized Right to Fit Under Nearly Any Handguard
Designed to fit standard .750 gas-block journals, this Aero Precision AR-15 Low-Profile Gas Block is machined from hardened 4150 steel and features a phosphate coating that protects it from corrosion and wear through its service on your rifle. The low-profile design fits underneath most slim-profile handguards on the market, and the design ships with set screws that lock the block into position and keep your rifle secure. A roll pin is not included with this gas block. Aero Precision recommends the use of non-permanent thread-locking compound on the set screws, should users decide to use thread-locking compound at all.
