drkstrw 15 Posted April 12, 2014 Report Share Posted April 12, 2014 My saiga 20 gauge stove pipes every other shot. I am at the point where i think the gas holes need to be enlarged and i have no idea how to get the gas block off. it is mounted different than my Saiga 12 gauge. Is there anyone local in the Detroit, Michigan area that can do this work? Quote Link to post Share on other sites
magsite20 1,664 Posted April 12, 2014 Report Share Posted April 12, 2014 have you tried different ammo and/ or a lighter recoil spring? Quote Link to post Share on other sites
gunman1 1,753 Posted April 12, 2014 Report Share Posted April 12, 2014 Is it converted? Did it shoot okay before conversion? will it cycle slugs? This is typical with the S20, that's why I don't try to shoot low power ammo, just slugs and buckshot. Quote Link to post Share on other sites
Wagnikov 186 Posted April 12, 2014 Report Share Posted April 12, 2014 I have struggled more with the 20ga than any other to get it running. I'm on round 3 or 4. I have (4)-.093 holes in barrel, fully relieved gas block, completely profiled hammer and bolt, mirror polished all friction points, and Winchester super target is the cheapest ammo I can get it to run. 6.50$ or so a box. But on low power rounds it's very very picky. I have installed, but not tested, jt reduced power main spring, jt guide rod, jt light recoil spring, and md arms booster puck. All of these are minor tweaks, but I have done the standard hd fixes that are typically overkill. So if this round of testing fails to provide 100% reliability I will shorten the gas system on a full length gun. Also don't get me wrong it is much improved. But it's an ak not an airsoft, 99% reliability is unacceptable, and dishonoring to the memory of Mr Kalashnikov RIP. What I'm saying is don't be afraid to over-gass it, others can chime, in but on the 20ga it's not hard to do. If you have any doubts knock that sucker off. If you happen to get too much(doubtfully) install a tac47 plug to dampen the heavy stuff Edit. Over gassing is *hard to do(not likely) Quote Link to post Share on other sites
drkstrw 15 Posted April 12, 2014 Author Report Share Posted April 12, 2014 shoots 3 inch just fine will not cycle 2 3/4 inch most of the time. Quote Link to post Share on other sites

drkstrw 15 Posted April 20, 2014 Author Report Share Posted April 20, 2014 I sent it off to JT Engineering. Jack does good work and i trust he will get my 20 gauge up and running perfectly. 1 Quote Link to post Share on other sites
Wagnikov 186 Posted February 26, 2015 Report Share Posted February 26, 2015 10months later lol, how's she run? I sent it off to JT Engineering. Jack does good work and i trust he will get my 20 gauge up and running perfectly. Quote Link to post Share on other sites
madjack 0 Posted February 26, 2015 Report Share Posted February 26, 2015 Are you shooting wal mart value pack ammo? The main problem that I and others have observed is that the magnet on the extractor needs to have something to grab a hold of when extracting. The extractor doesn't grab the alloy primer casings and you need to shoot brass. My S20 works fine with Brass and buckshot and slugs. I get bad reliability when I try to use the alloy primer casings. Which magazines are you using? Quote Link to post Share on other sites
Wagnikov 186 Posted February 26, 2015 Report Share Posted February 26, 2015 "Magnetic Extraction" hummmm lol Quote Link to post Share on other sites
Wagnikov 186 Posted February 26, 2015 Report Share Posted February 26, 2015 Magnets don't work on brass either. Only on ferrous metals(thoses containing Fe aka iron) it's also the reason you blood is red. If it rusts(oxidizes) red then it has iron in it. Brass oxidizes green. Aluminum-white. I don't believe that ak variants utilize magnets. The extractor claw pinches the case agains the opposite side of the bolt head, and there for can/should hold it when empty. Edit: "Magnetic Attraction Extraction"! Quote Link to post Share on other sites
madjack 0 Posted March 12, 2015 Report Share Posted March 12, 2015 Yeah, I had been under the impression that it was magnetic somehow. I swear I heard that somewhere. Sorry for my ignorance. I do believe that the extractor is made for the thick brass casings though. I've never had an issue shooting buck or slugs with the factory mags or the clear 13 round mags by Sanders.

Is there anyone local in the Detroit, Michigan area that can do this work? You can do it yourself.Pop the pins in your FSB and knock it off. If your gas holes are covered by FSB port, open it up so you can see the holes.I enlarged the 3 factory holes from 5/64 to 3/32, then drilled an extra hole at 5/64.I installed a modified Molot trigger group because it sits lower than a G2 and cuts down on drag of Bolt Carrier.Polish the rails a little.Buy the Suprema ammo at Wally World.5.88/box. It is cheaper than the Federal bulk and Winchester Universal and much higher quality. Have fun! The Csspecs mags are awesome and shoot 2 3/4. 1 Quote Link to post Share on other sites

Pantera2 7 Posted May 4, 2015 Report Share Posted May 4, 2015 I'm currently breaking in my S20. So far the only reliable cycling shells are the Remmington express 2 3/4 . Another 50 or so rounds then I'll try some less expensive shells. Quote Link to post Share on other sites
Pantera2 7 Posted May 13, 2015 Report Share Posted May 13, 2015 I just finished running a box of Suprema from wallmart . Pleasantly surprised. Only 4 FTEs . For only $5.88 per box it cycles well and almost a third of the cost for Remmington. Quote Link to post Share on other sites
TxAgSaiga1979 16 Posted July 2, 2015 Report Share Posted July 2, 2015 I shoot remington express buckshot most of the time through mine. For lower power rounds you gotta open up that gas block; I've even had to open it up 2 clicks with really crappy ammo to get it to cycle. Quote Link to post Share on other sites
