What makes you feel you need one?
I've had a couple of different buffers in a couple of AKs, and they were the only AK's I've ever had any troubles with. Those troubles were usually due to feeding, or I should say, the lack of it. The trouble stopped as soon as the buffers were removed.
If you look at the rear of the receiver on the inside, do you see any indication of the bolt carrier is actually impacting the receiver? I have yet to see any indication that it has on any of my AK's.
An indication to me that they are not necessary is the fact that the "real" guns dont come from the arsenal that way, and I dont remember ever seeing one spec'd in any parts list.
Hmmm, kind of makes you wonder, dont it?
