This is a mag change demo from the March 2012 Subgun match at Port Malabar. I'm running a Saiga-12 K. http://www.youtube.com/watch?v=8wVZ_lNjFa8 This is one of the stages at the March 2012 subgun match at Malabar. It was a three gun match that day and I was running a Saiga-12 K, an UZI SMG with a Gemtech Mossad Suppressor, and a Glock-19 C. There were mandatory mag changes for the shotgun. http://www.youtube.com/watch?v=PowS4tPkbTk

EDIT: Assuming current part counts are correct with the iz-433, you have 17 potential parts to take into consideration. The muzzle attachment is the iffy portion on whether or not ATF see's a thread protector as an attachment per say but he's stated he's using a US made attachment. If the 433's op rod is the same as a regular S12 then you could potentially just install a tom cole rod. It's hard right now being the model is new to being imported here. At this point he would have the following imported parts: Receiver barrel mounting block bolt bolt carrier gas piston buttstock m

This 922r Bullshit really needs to be repealed!

If your gun does'nt run low brass consistantly on #1 I would'nt worry about it. I have two four port guns that run like that and I can't see any damage to the rear trunion. However, the carrier does make contact, but I don't see any deformation like some of the photos posted on this site of S-12's that appearantly are over gassed.

Ok so went to the range and it seems as though this didn't work for me. First 2 shots with winchester bulk went fine, but then every round either stove piped or stayed in the chamber. The universal stuff didn't even move the bolt back. I have 4 ports completely visible. I had the plug as far out as possible while still being locked into the detent so I'm not sure what the issue is. I have a css performance puck and the Auto Plug coming this week. I plan on polishing the bolt as a next step. This gun is unconverted although I have added some cosmetic stuff like a Tapco collapsible stock and utg

Take the gas block off and open up the access hole with a one size larger drill bit. I believe it's 11/32. Or, you can use a rat-tail file but don't enlarge the gas holes unless you have to. I did this with my newest 2011 S-12 and it runs 100% 2-3/4 bird shot with four gas ports at .063. Just open up the hole in the gas block first and make sure all of your gas ports are free of any gunk from the factory. I know it sucks that these Jerk-offs at the Izhmash plant can't seem to pull their heads out of their asses on this gas-block/gas-port issue, but the good news is that we know how to fix it.

You need to calculate area for a proper comparison. 4 ports @ .063 1/16" diameter calculates to 12,468 square mils 4 ports @ .070 # 50 Drill diameter calculates to 15,394 square mils 3 ports @ .079 5/64" diameter calculates to 14,703 square mils 2 ports @ .093 3/32" diameter calculates to 13,586 square mils 3 ports @ .093 3/32" diameter calculates to 20,329 square mils My 2011 Saiga has 4 ports between .051" and .066" Once I get the Gas block off I will measure with pin gauges to get the proper sizes. I want to go with the #50 drill bit. Malodave You may not need to go that large MaloDave, I

Fourth hole partially obscured by the gas block? Sounds familiar. As a matter of fact, I've been down that road twice already. Take the gun out and see if it runs. If it does good. If not, well that's where all the fun begins. If your gun is a 2011 four port gun, the gas ports should be about .063 or one 16th of an inch. The gun will run with these gas ports, but I had to open up the gas block hole with a slightly larger drill bit to expose the one gas port on both of my four port barrels. You can also use a rat-tail file to perform this operation as well. Also, you may want to check the gas

I have one three port S-12 and it's the only one I haven't had to fiddle f%ck to get running 100%. The other two are four ports and they both needed to be fiddle fu%ked.

I've read several posts on factory S-12's that will run bird shot on the #1 setting. So I would conclude that it depends on the size gas ports the gun came with when it left the factory. From what I've gathered, the factory doesn't seem to follow any guide lines on the size port holes they install in these guns. It's possible that you have one of the guns with four holes at .076 and/or the gun is simply well broken in.

I've used the trigger guard screw build on three Saiga 12's so far and they have all been successful. I had to cut the screw plate down to two holes because the S-12 has a two hole trigger guard. I also had to file one side of the plate at an angle so it would fit around the plate that holds the hammer pin on the right side of the reciever. In addition, I used the template from akbuilder to drill all the holes and everything worked out fine. I did have to enlarge the trigger guard holes a little so the button head srews would fit, but that was no big deal. I just worked the drill bit around in

I have three Saiga-12's. My 2008 model has a 2011 16" four port barrel that started out at .063 but I opened them up to .076. I also have a 2009 S-12 with a 19" three port barrel that I believe to be .080, because I can fit a 5/64 bit with some play in between. Lastly, My newest S-12 is a 2011 19" with four ports at .063.

I have just finished one of my Saiga-12's on a form 1 with a 16" barrel. I don't want to make this thread too long because it's been covered on another thread in great detail, but I opened my factory four ports to .076 and the gun seems to run low brass 100% on the number 2 setting. So far, the only brand I cannot run is the Winchester Extra-Lite 2-3/4 1 oz. bird shot. In addition, I ran the gun on the #1 setting to see if it would run low brass and it did run, but not 100% reliably. I ran three different brands of ammo on the #1 setting. Remington, Winchester Super target, and Rio, all 2-3/4

Sinse we have two recent cases where the court ruled that sporting pupose is null and void regarding firearms ownership, I don't know why the NRA doesn't simply take this 922r Bullshit to court and have it repealed!

This is what happens to brand new Saiga 12s around here.... Warranty schmarranty..... I have never owned one that ran good out of the box (out of 6) and I have never sent one back for warranty work, but they do end up running great. I've never had any good luck sending things out and have learned that I am better off on my own. Shit ends up looking nicer anyways. YMMV What type of paint is that on the receiver? I was thinking about making my light gray as well when I do the conversion. Rustoleum Professional Series High Performance enamel (Semi-gloss black). Apply a few light

if its a 19" gun, your most likely going to have problems, unless theyre 2 giant holes. if its a 24" gun, its normal. Thanks yooper. It's a 19". Here's a couple of pics though. I posted these before . . . . it looks like it might run, if not you can drill it to either a 3 port or 4 port. just make sure you drill the ports at the right angle, or get massive fouling. Thanks. They do appear big with the mirrors help, however, I've tried using a paper clip to stick in the holes but they don't seem to want to go in. Maybe I'm using the wrong angle. There is

What gas setting did you run it on? I was on the number 2 setting. I ran Remington 1 oz 2 3/4 brass # 7 shot, Federal 1 1/8 2 3/4 brass 7 1/2, and Winchester steel shot # 7. I guess these guns realy do go through a break in period but this is only my third Saiga-12. I guess I'll just keep my fingers crossed.

Well I think my new 2011 Saiga-12 just may be a winner! I took it out with my three port gun and it ran flawlessly with three different brands of bird shot, including the cheap Winchester. I guess I always expect the worst after having bad experiences with a previous firearm. Also, I sent in the Form 1 on this gun to SBS to 16", and I plan to send in the other Form 1 on the three porter with my next paycheck. Ha-Ha! I was at the gunshow today and I told my buddy I have plans to by another Saiga-12.

Hello Tony, it's been a while sinse I've been on this thread, but I have two form 1's on two Saiga 12's that I'm going to SBS to 16'. One of them has four gas ports and the other has three. My question is how large should I go with the ports on the four port gun? Also, I want to add a fourth port to the three port gun, but I'm afraid I may not have enough room after reading one of your posts concering the location of the gas ports. If I cannot add a fourth port, how large can I go without causing excessive fouling in the three port gun? Any addvice would be appreciated

In all this gas port Hoop-La, I almost forgot to mention that I just did a full conversion on a Saiga-12 for a friend of mine, and it just happens to be a three port gun that runs like a Timex. So based on my own experience, and being the owner of a four port gun as well as a flawless running three port gun, I can't see any advantage in four ports vs three ports. All I care about is that the gun runs without me having to fuck with it.

From all the info I've gathered concerning the gas port issue, it seems to be the collective opinion that more small gas ports produce less fouling in the gas block than fewer large gas ports. In other words, you can produce the same amount of gas with two ports as you can with three or four ports, but the fewer ports you have, the larger the ports have to be. The only advantage I can see in four ports vs three or two gas ports, is the amount of fouling the smaller number of ports supposedly produce. Personally, I'm happy with my three port gun, and I don't see any difference in the fouling th

Who knows? But they sure need to clear up this gas port bullshit and come up with a set of standards to follow. As far as 3 vs 4 gas ports, the best Saiga-12 I have is a 3 port. I swear all I've done is load the mags and pull the trigger with this gun. No fucking around with the gas block or sending it in for warrantee, just load mags, pull trigger and bang-bang-bang! Personally, I don't care if it's a three port or a four port so long as it works. I thought this new 2011 gun I just baught had three ports untill I got it home for a closer inspection. Fortunately, things seem to be working out
