Davehal9000 0 Posted May 28, 2008 Report Share Posted May 28, 2008 I've got a long barreled Saiga-12 I'd kinda like to cut down and fit with a Polychoke. With the barrel being tapered, what's involved in cutting the barrel and getting it down to the right diameter for threading? I'd like to be able to do this myself, so removing the barrel isn't an option. Quote Link to post Share on other sites

You may run into cycling issues requiring mods to the gas port holes. Barrel tapered? Are you sure? Wasn't aware of that. You can rent a die (22x0.75 metric) from Dinzag.

mscottrogers 56 Posted May 29, 2008 Report Share Posted May 29, 2008 Dinzag has a tutorial/ directions on his site as well as the rentals, search his name on this forum as well. http://forum.saiga-12.com/index.php?showto...57&hl=ports http://forum.saiga-12.com/index.php?showtopic=22652 http://dinzagarms.com/tools/tkr.html here's a start Quote Link to post Share on other sites
Davehal9000 0 Posted May 29, 2008 Author Report Share Posted May 29, 2008 It's a 24 inch I believe. I got it shortly before I deployed. If I do cut it down, I'd like to cut it down to 19". I've been told there's some taper to the barrel. Quote Link to post Share on other sites

I've been told there's some taper to the barrel. The gas ports may need to be opened up for the gun to cycle properly. You might want to ask Tony at Tromix since he has the most experience with this matter. Quote Link to post Share on other sites
TonyRumore 1,332 Posted May 29, 2008 Report Share Posted May 29, 2008 Your 22" gun could have been made with 3ea .073" gas ports or 4ea .073" gas ports. Pull out your gas regulator and look in the gas block with a flashlight to check it. If you have 4ea ports, you can just cut it down and be good to go. If you only have 3, then you will need to press off the gas block and add one hole.......or just shoot full power ammo all the time. Tony Quote Link to post Share on other sites
Davehal9000 0 Posted May 29, 2008 Author Report Share Posted May 29, 2008 Once the ports are taken care of, will there be any problem rethreading the barrel? Would the barrel be tapered, causing problems with threading? Quote Link to post Share on other sites
mib2nd 1 Posted May 31, 2008 Report Share Posted May 31, 2008 Don't you need to thread the inside of the barrel for the Poly-Choke? Quote Link to post Share on other sites
