Also, AK's shouldn't use recoil buffers. They can lead to cycle issues, leave the gun as is since it was designed to kick the bolt back in a "powerful/violent" way. Just grab the extra power spring and you'll be good to go.

Good advice. the recoil buffers in the market are too thick and soft. One should find a hard one and cut right in the middle. In other words, you could make two of one otherwise they will lead to cycling issues.

A good factory spring up to spec is all is needed. A tad harder spring will not hurt that is for sure.
