The Killjoy Industries A5 Single Skeleton Trigger. Give your A5 an intimidating look. Skeleton milling makes for a lighter weight trigger. This trigger works for the A5 Basic and E-Grip. It will require a custom trigger slide for the Response Trigger and Mechanical setups. Use the original magnet from your stock E-Grip and the stock pin and spring for the Response Trigger. Does NOT work with the A5 H.E.; look at the X7 version for that.
