Colt 7.62x39 AR15 available again CR6762

Given the short distance that the spent cases are ejecting, I think that a heavier buffer would likely result in the rifle short stroking. While the recoil is noticeably more than 5.56x45 AR15's, it's not to the point that it's bothersome. I have a couple of other 7.62x39 AR15's. I'll have to compare them and see if there is a difference.

Never shot the Geco. I heard it was weak. Better in an AK. PPU I read was better.

Based simply on the ejection distance of the spent cases, the Geco is weaker than most steel cased 7.62x39.

I used to have a Vepr and now own a Sig 556R. Recoil is definitely a bit more than 5.56, but feels spread over a longer period - more of a push. I find 7.62x39 satisfying to shoot. And arguably it's a more effective round at more realistic combat distances, limited to ball.

As to ammo, I've never shot any Geco, but I've been through a few cases of Tula/Wolf, Barnaul, Ulyanovsk, Golden Tiger, and Yugo. Have also run through a few rounds of PPU. The Yugo and PPU definitely felt the hottest, with GT and Barnaul following up, and the others behind that. I'm not sure if my subjective opinion lines up with actual chrony tests though, but I imagine it does.
