These rollers were the final items needed to restore an old cetme c to perfect specs. They raised my bolt head clearance from an almost out of spec .006” clearance to .0165” clearance. An educated guess on the size to buy, the plus 5’s worked perfectly. Could not find a clear reference to what plus size would equal what increase in clearance. I also bought plus 8’s, which had a slight (but correctable) glance issue in the bolt head. The plus 5’s worked perfectly, dropped right in, and gave me the clearance I was trying for. The rifle mfg wouldn’t even return an email, so I replace the ground bolt head, replaced the locking piece, and brought the old cetme right into spec with these plus 5’s. I’m very happy with the purchase.
Maybe not as good as a German roller, but good enough. Mine measured 8.065-ish.
