any chance they are re-chambered to 7.62x39???I think that the overall length of 7.62x39 would prevent it’s use in the existing mags and magazine well of the weapon.Plus the bolt heads would all have to be replaced since the case head on 7.62x39 is way smaller than 7.92x33.Might need to replace the recoil spring and buffer too.
I believe PTR makes an HK93 clone in 7.62x39. That’s pretty close, in fact, I’ve seen a few of the HK93 knockoffs modified to look a lot like an MP-44.
