Customer says that after loading and shooting, all rounds feed, Fire and extract as expected but if he loads 12 rounds, it fails to feed the last round. Even if he loads 8 rounds, it fails to feed the last round and jams forcing him to remove magazine tube to clear. Your thoughts on this greatly appreciated!
The hint is in the details. Last round fails to feed and jams. How does it fail? And how does it jam? Does the jam happen when he pumps forearm backward or forward.
Just based on the descriptions, a tired magazine spring could be a possibility. And the jam happens when he tries to pump the forearm back. But it is just a guess without the further details. -TL
Answer
Sounds as though the magazine isn’t pushing the last round all the way out of the magazine tube into the carrier. Could be several things causing this. Ken

Thanks guys, stretching the spring and cleaning everything up corrected the problem.
