I have a rifle from my buddy to "fix". He bought a faxon 18" with pinned gas block from Aimsurplus. I have a few 16" faxon socoms that are awesome.
It is on a carbine buffer tube and spring with standard carbine buffer. It doesnt eject the shell and jams.
I swapped bcgs same result. I threw it on one my lowers with an H buffer and and it will eject the casing but not pick up the next round. If will not hold bolt open on last round which leads me to believe its undergassed.
I stripped it down and reassembled it, exact same problem. I didnt check alignment of the gas port because of the pin job, It looked close I made a bad assumption not checking. I hand cycled 20 rounds through it amd now I will need to add heat to get the gas block back off.
Shooting wolf gold and lake city m193.
Any ideas?
Thanks,
Chris.
