going with the following parts, this is my first build of any type so not blowing the bank but leaving myself room for later. Stag A2 Buttstock Assembly (Stag A2 B/S) = $60.00 Troy Flip Up Rear Rail Mounted Sight - Black (FBSRA4) = $140.00 MonsterMan AR Grip - IN STOCK (Monster Man AR Grip) = $45.00 Bushmaster Lower Parts Kit (Bushmaster LPK) = $69.99 on the upper i got a good deal on a bushmaster M4 A3 at 468 shipped. just need to decide on the muzzle brake and lower receiver before the first stage of my build is done. looking to upgrade to optics later and maybey build another lower with the nice evil features and a bullet button. pics when the goodies arrive.
