[ARCHIVED THREAD] - Possible 9mm Bolt Issue

Posted: 2/1/2015 8:55:29 PM EDT

The bolt on my 9mm SBR is rubbing the inside of the right feed lip on every brand of mag I can find. I'm wondering if the bottom portion of the bolt is too wide. As I measure it, I get .350. It that normal?

What brand of mag block
Or lower are you using?
How did you narrow it down to the bolt rather than something off center?

I cycled the bolt with the FCG, barrel, and mag guts removed. I tried it with a different upper as well.

Not sure of the manufacturer of my bolt but it measures .355. and runs without issue with my cmmg lower. Could be the location not the width or the mag well off centered.
