Looking to build a dream AR-10 sniper! No idea what companies to look at. Will need Lower (With CA Bullet button ) 20" to 24" barrel Gas piston system 10 round mags (Thanks CA) Awesome Bi-pods Floating barrel yet full rail system (can't have too many rails on this one) Collapsible butt-stock Would like it to be in FDE or some cammo finish. I am on a waiting list for a SCAR-17 but I think we can build an AR-10 just as nice for half of $3,000 !!! Will decide on a scope later.
