Hi all I need some input.I would like to build an AR-15 for under $799. I have been told its not possible but have looked on YouTube and there are a number of videos on how to build one for a reasonable price . So can some of you that care to share help me out. I know the lowers are obviously something I have to buy through a gun dealer but the rest I am not sure of who has the better product and prices. My last AR was a COLT patrolmen decked out with everything I wanted but times got tough and had to let her go . Any suggestions would be helpful. thanks so much....
