This kit includes the magazine release, spring, and catch lock, all built to function together as a complete system. It’s intended as a direct replacement for worn or inconsistent components, or for new builds that need a dependable setup from the start. The geometry and tension are balanced to keep operation smooth without being overly sensitive.

Notice: All parts built as “Drop in” for any UGW Firearm. Usage in any other 2011 style platforms will need installation by a gunsmith.”
