I was looking to get the most accuracy from my Grendel when I started building it. I lapped it and bedded it with loctite first thing. I decided the loctite wasn't going to make the extension perfectly centered in the receiver so I put a .002 (after measuring of course) feeler gauge blade on the extension then put loctite all over it. It was a snug fit.
