Hi CMMG,

There are two letters on the chamber adapter, N and G. How do I make use of Go/NoGo gauge?

Thanks.

Wow, guess some shooters get pretty rough taking these apart. I've been doing it for
years and not giving it a second thought. Never had a problem deforming the rails. I did have one
dedicated collar that had too much plating on it (Spike's) carefully tapped the rails into place with
a small hammer.. Sorry about the rambling, guess I should know how far people will go to take
things apart when they really don't have a clue.. From the drawings I can imagine Pliers, Screw
Drivers and Hammers have been used....LOL...

I taught tech subjects for years. Had thousands of students taking things apart and putting them back together. Its amazing how brutal some people are with things. Worse yet, after they use "a bigger hammer" on it they complained when it broke. Never was it their fault. So, never underestimate how badly some people will mangle, twist, hammer, bend, break or otherwise abuse anything. Some folks just don't have a feel for mechanical objects.

I am like Dave, I have taken so many things apart over and over and never had a problem. But, we have had so much practice....I got mine fixing the things I broke! (Like many of us did!)
