Deformed case mouths


So I’m seeing this on my Zastava - over gassing issue? Going to load some spent cases that aren’t squashed and slowly cycle the action to see where it’s hitting. Heard that a stiffer spring may cure this - I have an M*Carbo Extra power AK recoil spring that I can use. I emailed Zastava to see if the spring in the 5.56 is the same as the 7.62x39.

Same as the spring extraction of the AR. I have a Daewoo DR with an ejector built into the lower also adjustable gas port ahead of the piston. I really think you can balance the spring with the system and specific load. Start with a heavy spring. If it fully cycles, you are done. If not, trim it down coil at a time until it does.

If you cannot get it to stop beating up the mouth, trim the brass down and get a 300 Blackout upper.

It’s an AK.

Thinking a spring comparison is in order - I have the original spring from my 7.62 AK, the extra power M*Carbo & I’ll pull the one from the gun in question and see how they stack up. Fortunately there’s an extra point of adjustment as this AK has an adjustable gas block, guessing I just have to find the right balance between the two. I’ve heard this is common with ARs, but neither of mine (.223 wylde GLFA or .308 Windam AR-10) have ever done this, kinda caught me off guard thinking there was something wrong.
Another thing I noticed on the other end is that there is some damage where the extractor is grabbing the lip at the base, but only on the 5.56. You can see where the ejector is hitting right above the green lines, & the red lines where the extractor is grabbing the case and bending it backwards as it ejects. I know I’m probably over thinking this, but I’m crazy like that. LOL

Use a colored marker and color around the mouth of the case.
Check to see if it is dragging or hitting. See if the color is scraped off.
Then see if you see where the color comes off on the chamber.
Nail polish may work better.

I thought they ate the brass/steel for nourishment. :grinning:

Don’t forget, sold to us by a country with a bare chested leader that does what he wants with abandon. I have seen the beast, and do not want any part of a row with it. AKs eat brass and chew up the unfortunate. Not a surgeon’s scalpel. An indiscriminate disposable tool for an expendable work force. I do enjoy it, but I prefer a precision rifle and a shotgun to defend my position.

Sorry for the rant. I do believe the 7.62x39 cartridge is capable of outstanding accuracy with the correct components. Also there are many accurate rifles in tha caliber. I just find most of the AK’s lack of ergonomics, precision and lrbho unfit for my needs. They are durable and can run full of mud. I have even see ones built in caves out of garbage run. Not my tool, but I will support anyone wanting to own one. Even if it means dying in a bed of brass to do so. My opinion has no bearing on anyone’s rights. FREEDOM!!

They do! They are designed to run steel case ammunition and will often chew up brass case ammo.
All part of the experience.

Zastava is Serbian not Russian.

Popular misconception.

AK’s also run 5.45 x 39 very accurately and 5.56.
Lots of folk assume they are crude and inaccurate, the truth is some are and some are not.
Check out some video of AK competition to see them being run out to 600 yards on iron sights.

Thank you for the corrections. As I look back on it, the AK is more of a class of weapons, like “bolt action “. I carried an M85 in 8mm while doing some work over there until Slick Willie shut down the war on drugs. I do agree, there is a vast amount of good in the AK system. As the original goes, it is as durable as a ball peen hammer. Even though I don’t have one, I will still defend the ownership of an AK with my life, unless the said AK is being used on me. In the same way, I don’t choose to own any pump actions other than a Remington 14 in 30 Remington. Just the choices I make.

The only way to legally play the AK game in the PRoMD. The pinheads would seem to have an issue with “assault-style rifles” chambered in native caliber. Same reason an M1A in .308 is no bueno, I imagine.

Better not let them know Polish AK’s are chambered in 5.56 for their Military………

Not really corrections, just additional information!
East German and Bulgarian are generally considered some of the best AK derivatives and I have to agree.
Larry Vickers owns an East German example as well as his Alpha clone. His two volume books are an invaluable resource into the AK world.

Honestly, they try to ban all of them with a bill every session it seems. They aren’t the smartest bunch but if they discovered that (and eventually likely will), yeah, they’d probably push for a ban

Actually had my eye on a number of his book sets.

They are truly great works. My wife has been buying them for birthday/Christmas/Father’s Day gifts.
I have the AK, AR15 and 1911 collection currently.

Put some silly stickers on it so the rifle will look less formidable.
