Yes my Brother did, he had both the 90 and 91, I got the 91 after he passed away, it has a longer barrel.. usually not a fan of optics on the AK, but this is very accurate, and I like the tru glo on it..I didnt know they even made a 91. I have a 90 with the same wood. Nice looking milled rec. I made the thumb hole bigger. Did you also?
