I had to cut my mag release spring down dang near 1/3 of it's original size to get a nice fit in my ATI stock. When I first put it in there it wouldn't even push down far enough to get the screw in. After I got a short screw (I was using a long with washers before because my ATI didn't come with the right screw) I cut it down some more because I'd have to jiggle and pull on the mags to get them to come out. After cutting it down all but 1 (the one it came with oddly enough) will fall out freely now that it's been cut. Anybody else have anything similar happen? EDIT: This poll is pretty much just for statistical purposes. Hopefully this will help people who consider buying an ATI to weigh what modifications they may have to make into their final decision.
