    Droog -

    I understand what you're saying. Oh yes they're fun to shoot but the ANTICIPATION and HOPING YOU'RE ONTO SOMETHING NEW when you're building away & brainstorming in the shop - well, that level of happiness is hard to describe. At least for me. I believe it's the same for just about everyone else here too.

    I am sincerely hoping you get'er up and running with minimum hassles and postive results. This may be a cliff-hanger.....

    Good luck!

    Thanks Hotbarrel for the confidence. I hope you are right.Seeing as how this is a Rrrrrussian Siaga barrel and 22mm Ill have to hunt down a trunnion. I may have to locate a 22mm AK 74 trunnion and mill the magwell out alittle.

    I think that the piston is going to be too short, when it fires, the piston will be mis-aligned and get caught somewhere on the front of the gas block.

    Im gonna cut a chamfer on the front of the piston to hopefully keep that from happening .We shall see.

    One possibility might be to design a two-piece telescoping piston head. For that to work you'd either need to incorporate a spring to extend the unit during recoil, or implement a retainer that prevents the piston head from leaving the gas tube.

    Droog -

    I would try chamfering the inside of the GB (funnel-like) before I'd try chamfering the front of the piston. Chamfering the piston may make it more susceptable to "blow-by", meaning some of the gas blast may slip around the piston head instead of pushing ON it. Like bad rings in a V8.

    Just trying to help - I've dealt with that one before. when using 3/16" long piston "plug". I had to make it "thread the needle" before it would work. It wasn't easy! Upper rail alignment was critical, and even the receiver SPACER came into play. My spacer is screwed thru a roll pin, and 1/2 turn with an allen wrench would make it work or not work.

    I believe you will accomplish the "super shorty shorty" successfully.
