Review: The Bushmaster BA50 Anti-Material Rifle
The BA50 is a precision bolt gun with a right-side ejection port and a left-side bolt arm. It's an anti-material rifle chambered in .50 BMG. 

The video has most of the pertinent info and I'm including some extra photos here for reference to things mentioned in the video.

One thing I neglected to mention in the video is that the BA50 comes black. I did a rattle-can paint job on mine because I'm weird that way and dig the contrast. 

The rifle comes in a beautiful Storm pelican case and is just about the nicest rifle case I've ever seen. Of course it's big and heavy!

The muzzle brake is an AAC Cyclopse brake, which doubles as a suppressor mount for the same-name suppressor.

Here are some detail pics of the receiver set, bolt arm, and controls...

My first shot on a 12"x12" plate at 550 yards.
