My 2 cents about a recoil buffer. I use a BlackJack Buffer in every AK variant that I take to the range. While an AK is built to last, I don't have a personal armorer to make free repairs, so a buffer softens the carrier impact on the rear trunion.
Also, AK173 noted that he/she needs a lighter recoil due to physical issues. The buffer doesn't do much, but it does soften the felt recoil a bit, and any bit helps. The other big recoil helper is the AK-74 style muzzle brake which does a great job cutting felt recoil.
I have a Romanian SAR-2 (5.45x39) that with the recoil buffer and the correct AK-74 brake and there is almost zero recoil, which allowed me to show off to a couple of ATF agents how first, is was semi-auto only, and second that I could hold it off my shoulder and when fired it almost didn't move at all. I asked one agent if he would like to try a round or two, and upon firing he remarked to his partner "You gotta try this".
As for the receiver, NDS was probably the first USA manufacturer that could be trusted to make a high quality receiver.
