Inception Designs Roller Sear Airsoft Barrel Accessories The M4 RIS EC1 NylonThis is a roller sear. It utlizes the largest bearing possible for the smoothest rolling action on the trigger plate. This works in all of our Inception frames, Empire frames and many old school frames, but we haven't verified it in all old school frames (there are just too many) so please be aware that it's use may depend on the frame you are putting it in. It will fit in any frame with a sear slot that is 0. 1875" or wider. Includes: Roller Sear
