I've been lurking for some time and i couldn't decide between 7.62x39 or 6.8x43 spc for my next build . I quickly realized wich direction i would go . I just put in a pre-order for a bison armory 16" light spr barrel . I can't wait to get my 6.8 build together and be an official member of the club . Just wanted to thank the 68 board , a good group of guys with a wealth of information on the 6.8x43 spc cartridge .
