Milled 5.56 or 5.45 Aks?

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

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
