Hi, I am planning build my first AR10 and want to use JP supermatch barrel and JP bcg. My question is that I know the barrel will come with a enhanced jp bolt so I might only need to buy a bolt carrier, but I am just wondering whether the cam pin and firing pin retaining pin are included. If not, I am curious whether other brand cam pin and firing pin retaining pin are able to fit in jp bcg.
Thanks
Thanks
