I went the high road on my last two AR-10 clone builds. where I saved money was contouring the barrel and chambering it my self. JD is good reciever! I went with Meag Arms set because of the universal tools used. (can use DPMS or Armalite parts) I use JP rifles BCGs. yes these cost but I like the relablilty. My triggers are CMC out of Texas. One piece drop ins.
