It sounds like it's tuned and running just fine. If it functions on low-gas setting with the choke on or off.. Just shoot it. Im not sure exactly what you're trying to figure out. Sounds like your just over thinking and worrying too much...🤔
You're probably right IndyArms, I know I'm splitting hairs, but I want to run high brass as well as low brass without beating the gun to death. This gun was in limbo for about three years now and I'm just getting back to finishing it up with a series of function tests to see what it will and will not run. So far it's looking good, but I want to get some feed back from some of the guys on this site who have experience running the Izzi 1/2 choke on both settings with high and low brass. I guess my question is, is it normal for the gun to run low brass on the #1 setting with the choke, and will it run high brass on #1 with the choke, without risking damage. As I said, the barrell is 14.5 with four ports .078 to .079 angle drilled at about 35 degrees so I don't think it's anywhere near over gassed, but the gun seems to run a little stronger than I expected for these numbers. I'm still trying to get more brands of shotgun ammo as the supply is limited now days and I like to run as many variety of brands when I do a function test on these guns. So far, I have run several brands of Federal low brass with success and two of them will run on the #1 gas setting without the choke. One of them is the bulk pack in the red box from Walmart. But so far, these two brands of low brass are the only two that will run on the #1 setting without the choke. But again, I guess my concern is the back pressure produced by the choke running both 2 3/4 high and low brass. If I weren't planning to run this gun with the choke in certain matches, I wouldn't even worry about it. Thanks for your input IndyArms.

I have a question concerning the back pressure produced by the factory Saiga12 1/2 choke. I have an SBS Saiga12 with a 14.5" barrel with four ports at .078 to .079 and it runs both high and low brass without choke on the number 2 setting. My question, is it normal to run low brass with the choke on the number 1 setting? It runs most low brass on the number 2 setting without the choke and it will run at least two brands of Federal on the number 1 setting without the choke. I don't believe the gun is anywhere near getting too much gas, but I like to run high brass as well as low brass and I would like some feed back from some of you guys. I've read some of gunfun posts and he seems knowledgeable as well as Bob Ash and others. Give brothers!

I'm looking for some info concerning the amount of back pressure produced by the factory 1/2 choke on the Saiga 12. I have an SBS Saiga 12 with a 14.5 barrel with four gas ports at .078 to .079 and I can run low brass on the #1 setting with the choke. is this normal? I can run a number of brands of low brass without the choke on the #2 setting and two brands of low brass Federal without the choke on the #1 setting. Does anyone have any experience with this particular choke on an SBS Saiga12? I like to run high brass as well as low brass. I don't believe I'm anywhere close to getting too much gas, but I'd like some feed back from some of you guys who have been there. Thanks.

Post up the mods and pics to help us troubleshhot your problem.
I wish I could but I don't know how to post pics on this site. I tried a while back with no luck. I'm still in the stoneage with these damned computers and electrical gadgets.

I'm sure that I'm the only one who's ever experienced this problem with a Saiga-12 but here it is. I am getting a round feeding half way into the chamber before the bolt face makes contact with it. It appears as though the round at the top of the mag is feeding itself into the chamber as the bolt is travleing backwards, and the bolt face is catching the very top of the next round in the magazine as it travels forward. I have to say that this is a fu*ked up situation that I've never seen in any single feed mag, but it only happens with my AGP magazines. Give brothers, Give!

I see...makes sense that you are going for a "historically accurate" build.
Keep us posted and post pics!
Yeah, I like the Factory guns I see on the Izhmash website and try to stick to that same look with my own S-12's. Buy the way Bob, I may want to do the thread and step down on the barrel of this gun. Do you offer this service and if so, how much is it and how long do I have to wait? You can PM me if you like. Thanks.

a 16" SBS?
Seems like a lot of expense for two inches. What are you building it for?
I run this particular gun and another S-12K in our three-gun and subgun/shotgun matches here in Florida

I appreaciate the feedback comrades. To answer your questions concerning barrel length, if you will notice, the S-12 in the videos looks like a Saiga-12K EXP-01 pictured on the official Izhmash website. I referred to this site in order to reproduce a Saiga-12K just like the one manufactured in Russia, minus the side folding stock. The stock and Pistol grip are the Warsaw Pact from Arsenal, and the trigger guard is the Factory correct S-12K from AKbuilder.com. Personally, I like the factory Saiga-12K and I try to adhere to the factory specs with all my S-12 builds. If I ever learn how to post pic's on this site, I'll post some close ups.

Here are two videos of a function test with a Saiga-12 that I recently shorted the barrel to 16".
The gun has three factory ports that I believe messure .073 and have not been enlarged.
The first run was shot with Remington 2-3/4 # 6 birdshot.

[/media]The second run was shot with Winchester Super-Target Heavy 2-3/4 # 7-1/2 bird shot. I noticed the Winchester ran slightly hotter than the Remington.

These videos are a function test with a Saiga-12 that recently had the barrel shortened to 16" . The gun has three gas ports that have not been enlarged in order for it to function. I believe they messure at the factory .073. The first run was shot with Remington 2-3/4 #6 bird shot. 6-24-2012.

My personal experience is that two of the three of my own S-12's cut to 16" ,did not need the gas ports opened at all and both guns run high and low brass on the proper gas settings. One of my S-12's did need the gas ports opened, but I only opened them to .076 after I test fired it to see if it would run or not. I beleive in most cases, if you don't go any shorter than the factory 16.9 inches of the Saiga-12K, you will likely not need to open the gas ports. What most people do on this site, is cut thier barrels so short that one has no choice but open the gas ports. That's probably why so little info is posted on factory gas port size in relation to the S-12K. That's my 2 pennies.Greetings,
I recently purchased a brand new Saiga 12 but unfortunately only model S, with long barrels where available. I would like to shorten the barrel to 12K standard, it means 43 sm-s. I tried to search for info on barrel shortening but was unable to find answer on simply question: do I need to alter gas system after shortening a barrel? I think the best place to ask about Saiga 12 is this place
Actually I want to shorten it to 46 sm and wonder if I have to do something more than just chop off the barrel? Any advises links to useful thread will be highly appreciated.Thanx in advance
ps
Plz note that there are no legal restrictions on barrel shortening, in place where I live.

Evlblkwpnz's post is very informative, but I was hoping that someone would have manufactured a cutting tool that cut the step down after the thread was cut. Something that uses an alignment guide similar to the one used with the die set offered by Carolina Shooting Supply.

I'm referring to the factory choke manufactured by Izmash known as the 1/2 choke or mod choke would be the equivilant manufactured by CSS. The gun runs low brass as normal on the #2 setting with the exception of two brands of Federal low brass that will run on the #1 setting without the choke. My concern is the back pressure the choke produces running both high and low brass because the gun runs low brass on the #1 setting with the choke. Is this normal and is it safe to run high brass with the choke? I know, it's confusing and I'm racking my brain as well.
