Exactly.... You guys got the go ahead from MacGyver... I'm keeping mine factory until it poses a problem...
Mine posed a problem. After numerous times with it unlatching the magazine, the magazine finally disappeared and left me in the woods with a single shot. Nobody would accuse me of being a gunsmith, but I didn't have much trouble grinding it down. Nobody would accuse me of being an artist, either, but the RAR isn't exactly a work of art besides its functionality. I see no need to buy more parts and install them.
The 10/22 has the same problem, but I have to be more careful with the fix on that because of the desire to reload it more quickly than the RAR.
