Product description
The Aero Precision Low Profile Adjustable Gas Block is a gas block designed for AR15 rifle gas system tuning. This gas block fits barrels with a 0.625 inch gas block journal and provides adjustable gas flow control for rifle operation. It is used to regulate gas cycling within direct impingement systems.
The Aero Precision Low Profile Adjustable Gas Block features a nitride finish and a low-profile design compatible with slim free float handguards. The adjustment screw uses a spring and detent system and offers 15 gas adjustment settings. In standard configurations, the block channels carbon fouling into a sacrificial chamber to reduce buildup. The design is user-serviceable for cleaning and maintenance. This gas block attaches securely to the barrel and supports controlled gas system tuning in AR15 rifle builds.
