Ben's Review of GLFA AR-15 Complete Upper .450 Bushmaster 18in, S/S

Haven't had much time with it yet but man what a beast of a round the .450 is. Have only put about 20 rounds down range, testing functionality and then just for *hits and giggles. Couple of part swaps still needed for me to be happy with the build but so far no FTF or FTE. Fairly light weight, manageable muzzle rise. Can't wait to have all the bits I want on it. Probably 5 star at that point.
