I have a Romanian wasr 10 and am having such a hard time trying to get a modern polymer furniture set on it. Specifically the upper hand guard. I tried an ATI set that didn't fit. Now I am trying to get a Tapco set on. The upper hand guard just seems to big to fit between the collars on the gas tube. Does anyone here have any experience with this? I am considering getting my dremal out to do some fitting but want to save that as a last resort.
