I have a CETME rifle that shoots great, but doesn't have a bolt gap. I ordered a set of +2 & +4 rollers to change out the existing rollers. I pulled the bold head and was happy to see it was not ground, and the length was exactly 1.835" as it should be. However after taking out the existing rollers I found they were already +4 rollers after I mic'd them. I put in the new ones in case the existing were worn, but still no gap. Any one know where to get larger rollers, or have any suggestions? Thanks!

Just to make sure, you are using a filler gauge to try to determine the bolt gap, correct?

As far as I know, there are no larger rollers. You are in the same boat as me. My rifle is out of spec with +4 rollers. I was advised at another forum to try a new bolt assembly. Which I haven't got around to yet. If that doesn't work, I was told the barrel would have to be reset to get the rifle's headspace back in spec.

When the rifle is in battery, does the charging handle assembly have any back and forward play? Or is it tight between the bolt carry and charging tube stop?

Good Luck and keep us up to date.

I found this CETME video very interesting. End result, that if you want more bolt-gap you need to have the barrel pressed in further (or "reset" I guess is the term). My bolt gap is pretty tight to specs. Talk with a gunsmith and maybe it can be done.

Thanks Jake & Black Wolf. Yes I was using a filler guage to check the bolt gap. At this point I'm not sure what I'll do. I just spent $28 on rollers that didn't help. I hate to spend another $100 on a new bolt assembly to find out that won't work either. I have a friend who has a CETME that's in spec so maybe I could put his bolt assembly in my rifle to see if it gaps correctly. If not then I'll just leave it as is as it would most likely need a barrel re-set job. I have a good sized mil-surp collection that I shoot, and I don't shoot the CETME that often.

Yes, if you've run out of roller, you'll need the barrel pressed and a new oversized barrel pin used.

This guy'll fix you right up, as it's a simple procedure. http://www.big50hk.com/
