Is it Bulgarian or US made or some other manufacture? Does KVAR sell it?
This one looks very similar.
It also seems similar to the grip on a Yugo? AK but seems more comfortable––thicker, softer rubber. If I recall correctly, the grip on a Yugo is hard and a bit thin.
Bulgy made SAW grip. http://www.k-var.com/shop/RPK-210B.html
Yes, the other one you posted is the same grip.
