The problem with cutting the piston extension is that it's a permanent modification. Simple job to remove the piston before you leave for the hunt...then just clean the rifle, slip the piston back into place and it's the same semi-auto SKS as before. The gas piston only travels about an inch or so down the gas tube before the extension and spring stops reward travel, at that point the gas is escaping the small pressure relief hole in the gas tube and the gas in the barrel is following the bullet out of the muzzle. remove the gas piston and the only difference is that the piston won't be there to cycle the action. My suggestion would be to locate a Mosin Nagant and use that...but only if you're inclined to spend under $200 for a new(to you) firearm. From what I understand about PA hunting laws...you aren't required to use a bolt action...it just has to be MANUALLY operated...i.e. converted semi-auto.I think you're on the right approach here, but cutting off the rear two thirds of the piston extension would do the job without the chance of excess gas squirting back into the receiver. With the recoil spring still in place the rifle would essentially be a straight pull with spring loaded bolt return.
