Overview
The Luth-Ar Low Profile Gas Block is designed for use with .750 diameter gas tubes, providing a reliable gas flow to ensure consistent cycling of your AR-15. Made from steel with a phosphate finish, this gas block offers durability and resistance to wear while maintaining a low-profile design that fits seamlessly under most handguards. This component is commonly found in standard AR-15 builds where space is a consideration, making it ideal for both tactical and sporting applications.
