Hello,
I know that many people have complained about the unreliability of the 9mm Feather AT-9 carbine. Well, the main cause of FTF (feed) is small chip(s) missing from the bolt face due to improperly seated aftermarket UZI mags. Apparently, many of these off brand mag's lips can take a small ridge off the bolt which is there to properly seat fed rounds. Or, it's because the round is in a twisted position. The only solution is to replace the bolt, but first make absolutely sure the mags fit snugly. Only true IMI mags seem to work. This problem may be why Feather designed multiple bolts for this gun ....
