- Threaded Bolt Catch Roll Pin - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included). 1/16" Hex Key required for assembly

- Increased Magwell Flare - Increased the flare of the magwell to aid in quick and efficient magazine changes
- Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well
- Made in the USA
