Ok guys..I seen something from troy that I loved...the m7 upgrade kit...short barrel ar15 upper 7.5 I think..and I wanted to know if I could take the upper and put it on a pistol lower and take the magpul stock it comes with a swap it out on my ar...the kit saves me from having to buy back up sights and its perfect because that is the same exact stock I was going to buy for my stag ar15 rifle with 16 inch barrel....so is it legal for me to get the kit and mix match the stuff or will I just have to take the brownells shaft and peice my stuff together the old fashion way? ..
