I finally ordered my .308! <thumbsup> Now I wait <munch>. I decided on the Armalite 16" AR-10(T) CARBINE 7.62 SST. BLK w/forward assist. I'm happy w/the price, but now I need rings, optics, buttstock, etc. Does anybody know if those fiber/tubes allow for bi pods, attachments, etc? When I get it, I will post pictures once I figure out how. By the way, I am really happy (can you tell?). :banana:
