Hi, I'm kinda new here, but I've had a Saiga IZ-240 (AK-74 configuration) for a few months now, and I've noticed that it has a tendency to missfeed with almost all of the mags that I use. The only one that feeds properly every time is a new Bulgarian magazine. I also have a circle 10 that occasionally missfeeds, and three promags that barely work at all. It's clear that it's a magazine issue and not a problem with the AK itself, but at the same time I do think that there is something that could be done with the bullet guide or something to help eliminate the problem. Anyone got any ideas?

You could post a picture of the bullet guide. It's really odd that one of your circle tens doesn't always feed properly, and due to that, I assume the issue is with the rifle. Do you see anything visibly wrong with that magazine, or is anything about it visibly different from the other circle ten that does work? I would get more military mags. If they don't work, then you probably need to reinstall or replace the bullet guide.

The magazine that feeds properly isn't a circle 10. It's some other Bulgarian mag, but it has the caliber and ammo capacity printed on the side. It's a pretty high quality mag, if I do say so myself, but I have no clue who makes it.

Anyways, here's a few pics of the bullet guide:

On an unrelated note, is there some sort of code that I can just type into my post so that these images can just be visible? I honestly think it's faster than attaching them all, and I'm used to the code on other forums. The format I'm used to is

When you say missfeed does the bolt miss the round? Does the round miss the chamber as it's being pushed?
First thing I would look at is mag protrusion into the receiver. The top of the mag should be touching the bottom of the lower rail and ejector. If the bolt is touching only the very top of the round as it comes out of the mag, it'll nose-dive causing a jam. One thing I notice is the guide looks more like a 7.62 than 5.45.

The Bulgarian mag you have pictured is a commercial-spec mag made by ISD Bulgaria. It is all polymer in construction and does not come close to the mil-spec Circle 10, 21, or 25 mags in terms of durability or reliability. Promag is not even worth mentioning and should be burned and forgotten.

You should try using mil-spec 5.45 mags (Circle 10, 21, 25, Izzy, Tula, Polish Tantal) before you reach the conclusion that your rifle is in fact at fault here. Being that the rifle is a Saiga leads me to believe that the mags are more likely at fault, but the rifle could still very well be the reason. An important thing to consider is who did the conversion on your Saiga. If it was done by Century, then it could very well be the rifle. If it was done by some guy in his garage, then it could very well be the rifle. All of my 74s have had no problem with any mag I've used on them, but my rifles were built with proper bullet guides already installed to the trunnion at the factory.

It also would be an excellent idea to check the headspace of your rifle. As you said earlier, you have the Bulgarian mag that does feed properly every time with no hiccups whatsoever so it is likely a mag issue, but to be sure, the rifle should be checked.

To post images, look at the "reply" toolbar where you can change fonts and font sizes and click on the "picture icon" which is a small image of a palm tree. Once you've clicked on this icon, you can select between two tabs which will allow you to insert a picture from your PC hard drive or from a URL.

That's nearly exactly what it does. The bullets end up hitting the bottom of the trunnion rather than sliding into the chamber. And if what you're saying about the bullet guide is true, then that may very well be the issue. Thanks for the insight.

Like I said, that commercial mag actually happens to be the one that feeds flawlessly, and I do have a circle 10 that I've tried shooting. It missfed about 1 in 10 times, thus I find what you're saying a little hard to believe, no offense. I have also since learned that Pro-Mags are generally junk, so I'll see if I can pawn them off or something.

Yeah, I'm probably going to look into that as well. The accuracy feels a bit off lately, in addition to the occasional missfeed, so I'm thinking that maybe the missfeeding could have led to a headspace issue, or vice-versa. Who knows. Regardless, I'll see about getting it checked, or getting tools to check it myself.

Headspace has nothing to do with feeding. Post a pic of the rifle with the mag inserted. And a pic of how the bolt is hitting the rounds as they come off the mag.
