Hi Gundoc.
NZGUNS are still working on a billet bolt lock for me. A tough ask.
I will look at a shim. The clearances certainly don’t help the issue.
In the mean time they keep suppling the investment cast versions. Think 6 so far. Lost count.
They are also getting a heavier buffer manufactured for me currently.
This is all under warranty so they do stand behind the gear.
