Aero Precision
Overview
The Aero Precision .625 Low Profile Gas Block is designed for a seamless fit on your AR-15 build, specifically accommodating a gas tube while maintaining a low profile that allows for the installation of a handguard without interference. Made from steel and finished with Nitride for durability, this gas block features a set screw mounting type that ensures a secure attachment to the barrel. This component is commonly found in builds where space is at a premium, making it ideal for lightweight or compact configurations.
