Milled 5.56 or 5.45 Aks?

metallurgy issues.

Sounds like they cheaped it out and didn't harden properly. Just being cheap...

Before the introduction of the 5.45x39mm Soviet cartridge they had necked down the original 7,62x39mm case to 5,6mm. It was called the 5,6x39mm Russian and tested during the 1950's but never issued for service. Finland did adopt this cartridge as a commercial small game cartridge called the 220 SAKO and was used in the small SAKO bolt action rifles

I've owned both, and much prefer the 5.45. True not every outlet has it, but cases are cheap ( I always preferred the "Golden Tiger" Russian vs. the Wolf ). As stated before, mags are much much cheaper too. I had a Bulgarian that I mounted a Russian PU scope on (see Gun Parts Corp ), and it was a blast to shoot.

Yes, they went cheap all the way.when they first came out, everyone was calling it the new gold standard in American ak's,but after about seven or eight months after its introduction, people started noticing runaway headspace and they are now known to be grenades around the 5000 round mark(5000 rounds should be barely breaking an AK in, not the death of it). I have about 4000 rounds through mine now, and started noticing headspace changes around the 2500 mark. Chipping of the locking lug shoulders mainly, and deformation on the bolt lugs. Several American companies seem to be having the same problem. I will continue shooting it as long as it is safe to do so according to my gauges, just to get some use out of it because I could never in good conscience sell it to someone else that may end up getting hurt with it that would not take the care or time to gauge it. So I'm stuck with it. But at least I have a couple comblock examples that run like a clock so I just chalk the American example up as lesson learned

Interesting, a service AK in 5.56. I had a Norinco with selective fire a while back and rung it out on Military reservation as much as possible. It wasn't too bad...

Arsenal makes a good AK in 5.56 called the slr-106 , and those are still pretty easy to get ahold of from my understanding. They are made using Bulgarian parts. Circle 10(Bulgarian) also makes a great 556 magazine. There is no difference in accuracy whether using a milled or stamped receiver. I own both variations and I can personally tell you there is no difference from one to the other except in weight. The milled receiver feels sturdier, but as long as the stamped variant is made to mil-spec, you won't have any problems. Just try to stick with combloc examples, American companies making ak's still haven't gotten all the bugs worked out yet, mostly metallurgy issues.I have an american-made c39 V2 that has a milled receiver and it is eating itself alive from the inside because the metal is soft in the front trunnion and unfortunately on the bolt itself, I have to check the headspace on the thing literally every time before a range trip. Even though the c39 V2 shoots a 7.62 x 39, it still should not be disintegrating on a milled receiver. Weather you end up getting a milled receiver or a stamp variant, just go with one of the combloc rifles and you should be okay

I have a 106 and agree with you on all statements.

I had no real grief with mine either...actually. Not too bad on auto either.

It's actually my Wife's rifle, at least what I tell her.

Nice rifle gun Papa! I love the plum front furniture (unless it's a trick of the light from The flash). I've always thought it looked good on the AK platforms. And you did exactly as I did, got to have the bayonet too or it just doesn't seem right ha ha ha. It's hard to go wrong with arsenal. These rifles can take a beating and keep right on chugging along

No they're not... They mostly dried up mid-last year. You can still get lucky of course and stumble across one.

I personally sold mine last year. As much as I liked the idea of an AK in 5.56, it wasn't very accurate even by AK standards. If I used 77gr or heavier I could get some decent groups, but that isn't very cost effective for an AK.
