It seems like there might be something wrong with the mags. The bolt is unable to push the round out of the mag and into the chamber. The tip of the bullet is getting stuck on the feed lip it seems. It worked ok if I held the bolt shut and worked it manually pulling back to eject and pushing forward to load, but letting it cycle on its own it can't get the round to move forward. I was thinking I could polish the feed lip where it is getting stuck, idk. I purchased 6 bx25 mags, but I only brought two of them to the range. I might try them all next time and see if any of the others work.
Thanks
James
