well i saw this on PBnation so i thought i would go ahead and do it. well basically what it dose it File/grind off the extra metal that dose not actually get used and just makes it heavier and gives it a bad air flow. Suposedly with this done you can lower dwell and pressure and in theory makeing the gun more efficent. well as i have a unicorn bolt in my gun it cant help to go ahead with it. Now this has taken me about 2 hours of fileing as i dont have access to a grinder and it could easily go completly wrong with a grinder. Well here is some finished pictures if you have any questions dont hesitat to ask me. I will update later on when i have found out if it works
i may also keep fileing more and more off to see how thin it can get befor it snaps.
