Help my Grendel pistol isn’t accurate

[montana]

The 2 nubs that hold the roll pin for the bolt catch/release. I'd have to tear my gun apart to show you wear.

The bad lever and it's clones WILL sit Cockeyed when you use them enough. That rubs the steel against the ears/nubs when used. I single feed at matches, and use it a minimum 44x a match and every practice. That's like 44 mag changes a day (minimum), 4x a week. Wear is accelerated in my use.

My friend built a 308 and didn't like the play he had with his BAD lever and shimmed it too. Using the cheap feeler gauge for shims was a good idea..
