I've started work on an Apex Romy RPK kit and barrel. I've got the barrel pinned to the trunnion. When I look at the parts there is a ring that looks like a cleaning rod guide. It seems to be ready to press and pin to the barrel. From the size it seems like it would go between the GB and FSB. Is there a standard place for it? I'd be inclined to put it midway between the two. Is there a standard place?
The barrel from Apex looks good. The barrel is oversize where all the pieces go but barely so it will be easy to get a good fit - no knurling.
I do have one bitch. I was pleased to see a US marking on it. Unfortunately, it will be covered by the RSB. Oh well.
