I have an Olypmic Arms PCR-02 (16", A2 upper). I recently changed out the upper receiver (only, not bbl or bolt) for an RRA flattop. It had a little trouble mounting to my oly lower, so I took a needle file to the rear takedown pin hole in the lower (since I've heard that Olys are often out of spec.) Before filing, I couldn't get the rear takedown pin all the way in. Now I can. But occasionally, mags which worked fine before the switch will cause me problems: I will get a round that hangs up on the feed ramp (or just below). If I jiggle the mag forward to back, the round will slip in. Any suggestions? My first inclination is to break out a dremel and slightly enlarge the feed ramps, then polish them. Could this be a bad idea? Thanks in advance! -fiz |
