Sarge Posted February 24, 2017 Share Posted February 24, 2017 During my gun feeding escapades I noticed something odd with my STI mags. With my 170's i can thumb off rounds from a loaded mag and all rounds present in a nice nose up position one after the other until empty. With all 8 of my 140's once I thumb off the first round all subsequent rounds present in a low flat manner and will not pop up to a nose up position. To eliminate the obvious, the 140's are all within spec at feed lips and springs are good. I even bent the spring back near the top as I read worked for MBX mags. I also crammed a 13 coil spring in there and it is super tight and rounds still don't pop up. Makes me wonder if this is normal? Again EVERY 140 I have does this Link to comment Share on other sites More sharing options...
