This was supposed to be an 8.4mm roller. Ordered two. Both are undersized and measured at about 8mm. Waste of my time. At least mic these things b4 you sell them. If it mics at 8mm sell the darn things in the 8mm category !

I had an old CETME that I bought 20 years ago and never used. After retirement, I started getting into small projects and discovered "bolt gap." The gap on my CETME was non-existent. After some research, I decided to change the rollers to a +6. HKParts had them in stock and shipped them quickly. After watching a few videos, the old for new roller swap was easy. I plan on using HKParts in the future.
