Saiga 12 cycling issues, low brass issues, issues issues issues!&#


Recommended Posts

I would follow the advice above and try it without the quad rail. Also try running federal bulk ammo instead of winchester. Your gas ports are in alot better shape then mine and mine runs federal without a hitch now. Have you polished the top of the hammer at all?

If you haven't taken off the quad rail completely do it and put the stock hand-guard back on, I have built at least a 100 or so S12s and every once in a while we see one that doesn't like the quad rai

Well right now im in the process of polishing the bolt n carrier. After this i will pull the gasblock and drill my ports to 3/32. Then give it a few test runs. If im still having problems i will start

I am the king of impatience! But we gotta get the thing running! Surely some of the pro's here will help some more! this maybe a challenge but it isn't an impossible one.   no clp isn't the issue! I

Yes, and make sure those Promags aren't squeezing the shells. They tend to collapse a little and cause issues.

If they are, there is a fix.

Not converted, but did install a collapsible stock, pistol grip and quad rail. When painted, no internal parts were painted. I checked the gas ports by using a pick. I haven't checked that they were to the right tolerance. When I pull the bolt back, it doesn't feel like its grinding or being help up. If I don't let it snap back and ride it forward manually it holds up right where the bolt's shell release goes into the gun (for lack of better word). I don't know if that matters. I live in Gettysburg so if someone can help me out that's close to here would be awesome!!! I'm gonna have to find a vendor.

 

Check the installation of your quad around your gas tube. If you get it too tight, it can cause the weapon to bind up.

Doesn't some of those quad rails also block the hole in the gas block where gas is vented. If blocked didn't this also cause issues?

You said that if you let the bolt forward slow, it hangs up. This is the bolt hanging up on the hammer, and if you've properly profiled the bolt and hammer this won't happen. You want it so that even if you ease the bolt forward, you can't get it to hang up before it closes.

 

This is cheap and requires a dremel and some patience. I colored the parts of the bolt you do NOT want to touch (plenty of threads on this) with black sharpie, and carefully worked on it, profiling down then polishing, until I had smooth bolt closure. Since I did this I think I've had a single misfeed in about 500 rounds.

One more UTG quad rail problem.

 

Removed it and the gun cycled great. Ran 100 rounds today, and the last 25 cycled perfectly with a V-plug and light brass spring. Before, I needed slugs or 00 buck to get the gun to cycle without a misfeed or FTE. With the UTG quad removed, it cycled the OEM 5-rounder fine, and a couple of stovepipes for the 10-round ProMag gen2's, usually on the last round of the mag.

 

Like so many others here, get the gun to cycle properly before adding anything! My S12 needed a 3rd port drilled, which I had done by a local gunsmith. I also have Pauly's polish job, and with those mods alone the gun is now cycling the way Khrushchev intended!

I just dont see it being the quad rail. The gun ran beautifully right out of the box. The gun is only 2 months old. I shot probably 100 rounds out of it, all low brass garbage and it cycled fine. Never a misfeed. Then all of a sudden it just started jamming rounds. So with the quad rail and collapsible stock and eveything else that was on there the first time I shot it didn't make it skip a beat. It was odd that one day it worked, the next day it didnt.

Caged you out of Gettysburg PA ? I have my saigas worked on at a local gunsmiths in downsville MD. Its not to far from you. I had a real vodka special that he got running like a scalded dog. I had port issues and he does the conversion work. We can also meet if you like and try other parts combos if you like i havea few extra pucks and I had cobra here do bolt and hammer work so you could compare friction and see if there is any hammer bump going on when the bolt is cycled.

Yes, I am in Gettysburg, PA...I work in Taneytown MD, not sure if that is closer or not. Yea i'd love to test it out one weekend. See what could be going on. Its always good having another saiga guy look at it. No one I know has one up here, so when I even mention the problem no one has enough info or hands on experience with it to know whats going on. They have only "heard" of them.

Caged is in Texas...

 

Yeah you and MrBoomstick should get together sometime and compare guns. After you see how his cycles compared to yours, things will become very obvious. You can even try swapping out the bolt and carrier if he doesn't mind. That would let you know how much good it would do, or if you still need port work. If you came here that's what I would do. If the gun worked fine before then it's not the quad causing problems. You either have clogged ports, something wrong with the puck and /or gas chamber, the gas plug has been adjusted wrong, or some uneven wear has happened between the bolt carrier, rails, and ejector....and caused it to start hanging up the carrier.

Email me some pictures of the internals.

I would also check the ejector slot on the barrel:

There were sharp edges in the slot that would catch on the shell and would actually shave it:

Of course this affected the cycling, so I removed the barrel and filed/polished these areas. You might be able to do it without removing the barrel. I'm not sure if this is what's causing your issues but it's worth checking out.

Sorry for dropping off the conversation, but school is hectic. I'm on my med surge rotation. I happen to have my one saiga completely ripped down at the moment for duracoating. So if you still need to do a part to part comparison let me know we can set up a day to test it out. I. only in Chambersburg/ Marion pa area you not too far up the road.

I took it out on sunday and it fired like a dream. I left the quad rail on, but took off the top rail that holds the red dot. SO i'm going to put that back on and try it again, if it runs flawless again i'm just going to leave it go. Before sundays trip i had polished the hammer and BCG down a little bit more and filed out the opening in the gas block a little bit more. It ran high brass and low brass perfectly. No jams, no FTEs, nothing. I was very happy with it.

Are you sure you are installing the gas plug properly? Screw it in completely then back out to first minus, then adjust out from there. Just a thought, I find it odd that slugs and wally world specials are functioning basially the same.

Good to hear! When I removed my top rail my gun ran better also.
