@leaveyourego Here is another video on the short PTR/G3 K pattern. He goes in depth about the issues with the HK51 8â barrel he had and now the 12â barreled model.
Basically the guns ship with rollers that are usually too shallow and beat themselves up in the stock configuration. Getting the right roller size and maybe putting a combination comp/flash hider might do the trick as long as you donât mind the noise.
Honestly the 12â K pattern is the vibe
