a hatsan "smart valve" mystery:
i bought a hatsan semi and it came with the barrel removed, for shipping purposes.
i put it together and test fired it with higher velocity field loads (1350 fps), ...the gun does not cycle at all, not once. the bolt doesn't even move at all, except manually.
i disassemble it and wonder if it could be missing an o-ring on the end of the magazine tube, similar to a Remington 1100.
i never thought to question the lack of o-ring because it was never there upon arrival, and, never having owned a hatsan before i didn't realize it was suposed to have one.
i put an 1100 o-ring on (i read they will do as a substitute), and test fired it again. no change, no joy.
i pop a pipe cleaner through the barrel gas ports, ...they were free and clear.
so now i'm running out of answers.
here's some pics of the gas piston assembly. is anything missing or out of sorts?
thanks for any advice. i'm stumped
