Overview
The Evolution Gun Works Rail Top Gas Block is designed for barrels with a .750 diameter, providing a secure clamp-on mounting system that ensures stability and reliability in your build. Made from lightweight aluminum and finished with hardcoat anodizing, this gas block not only enhances durability but also allows for a streamlined integration with railed handguards.
