I just received my KRG Bravo from brownells for my Remage build and ran into an issue with the recoil lug. The recoil lug area on the stock is only 1.2190 wide, the recoil lug on my rifle is 1.2890 wide. Can I just file the section out wider on the stock? The recoil lug is part of the aluminum chassis so it shouldn't be hard to open it up, I just do not want to introduce any issues if I do open it up .07.
