ok people. lets see what everyone has out there. im sure everyone likes eyecandy and what a rifle is made of and just how few pounds you people have gotten it down to.
also im wondering what is a good LIGHTWEIGHT free floating tube that can internally house a gas block. i guess this puts BM vmatch and other 1 peice tubes out since i cant figure out how to attacth a gasblock under them.
Do all upper/lower receivers weight about the same or are there certain ones to look for. i know all RRA guns are heavier than normal, are there receivers a part of this problem?
