Bushmaster .450 Upper Complete Kit -
It’s called "Thumper" and it’s capable of taking any game animal in North America. Engineered to mount on your mil-spec AR-15 lower, this 20" model hurls the 250-grain Hornady SST/FT .450 Bushmaster bullet downrange at 2,200 fps. Though not designed as a long-range caliber, there’s nothing on this continent capable of standing up to the firepower of Thumper and inside 200 yards its accuracy is outstanding. Recoil has been compared to that of a 20-gauge shotgun. A tubular-aluminum forend allows the barrel to free-float from the nut forward to enhance accuracy. Chrome lining in both the bore and chamber makes the .450 Bushmaster easy to clean and extends barrel life. A five-round magazine is included.

Bushmaster .450 Upper Complete Kit Reviews:


Wow! What a rifle.....

I doubt I can add anything that has not been written previously but, I can confirm that the 450 Bushmaster lives up to its reputation. It is accurate and relatively easy on the shoulder. Off the bench, it shoots MOA out to 200 yards (I didn't shoot any farther). The recoil was similar to a 20 gauge. No issues with failure to feed or failure to fire. The only issue I can report is a shift in impact once the barrel heats up but, I doubt I will ever shoot that many rounds at deer or hogs. All in all, a really fun gun to shoot and gets a lot of attention from the others at the range....... Great buy.

Up-Date to first review

I had a chance to shoot the 450 BM at 200 and 300 yrds. Was NOT disappointed. 1-2” groups at 200 yrds and 3-4” at 300. Third shoot at 300 using a BDC I put the shot right smack in the bulls eye. The wind kicked up and the kids were getting busy so I didn’t have a lot of time to shoot but was able to hit the bulls eye at 300 yrds on the third shot. VERY impressive gun. Not just a 100-200 yrd gun, 100-300 yrd gun and most hunters I know are not shooting beyond that on typical game. Again, at 300 yrds it has MORE energy than a .44 mag point blank.
