Bought a diamond back ar 10 with 18 barrel and only had 1200 in the original gun . With bipod and optics you ' d be around 1500 I was told by the people at the gun shop I couldn ' t ever build one for that . They said the ar 10 world just isn ' t where the ar 15 world is yet . So buy a whole one and add on parts as needed , then sell the old parts to recoup cash . I ' m normally someone who says build them but I took the advice on this one . Love my ar 10 btw <| sep |> 2 , M 16 G 36 cBarratt kind of guy . Always played COD games on the lowest setting but 1 on this game is too slow even for me . Sometimes I go crazy and ramp it up to a 3 for Shipment . <| sep |> No idea . But I can give you a good stuffing recipe and maybe some football picks .
