Gregory Paul Posted March 11, 2023 Report Share Posted March 11, 2023 After around 200 rounds starting noticing spent casings had a u shaped dent where the bullet sits. Now, the bolt carry catches too far so you basically can’t load a magazine with out pulling on the Charging handle all the way back. See pictures. Any ideas?

Or the AR15 rifle buffer in the rifle extension. Whatever is being run here for a recoil system. Numbers are mandatory. Quote Link to comment Share on other sites More sharing options...
