| How many rounds through a c93 to determine if the barrel was pressed and pinned correctly? I cleaned it thoroughly and measured bolt gap (.009) before shooting it. After 100 rounds of m855, it's stool holding at .009. |

Yeah, going to measure what I have and order some bigger ones when I order some mke mags. Thanks for all the responses so far.
Quoted:
Most notice a change within the first few hundred rounds. I would think that if yours was going to move it would have started by now. Personally, I would get some rollers 1 or 2 sizes bigger than what is in your rifle, just because its on the low side. |
| 100 rounds again today, cleaned rifle and measured bolt gap, still at .009. I removed the rollers today and measured them, 7.98mm. Thinking about +4 or +6 rollers to get the gap a little bigger. I'll keep checking the bolt gap, but hopefully this rifle is one of the good ones. |
