Good upper for the price. - Radical Firearms Complete Upper Assembly .450 Bushmaster, 15in MHR, Single Ramp, Black, Box

Just finished assembling the rifle. Gave it just a quick test fire off the deck. It fed, fired and ejected which is a good start. I had to use a standard 20 round 223 mag because for reasons I'm still waiting to find my upper did not have the 450 mag in the package. As for accuracy, I'm waiting for the weather to clear before I can comment on that.
