Holy F%$@#ing carbine dude!!!
The Bushmaster BA50 Carbine is one hell of a 'carbine'. I guess you can call this 30lb beast a carbine being it's a .50BMG sporting a 22" barrel. Bushmaster does. Drop the [carbine] and it comes with 30" barrel and extended scope mount.
The .50 Browning Machine Gun round was used for the 2nd longest sniper-kill ever logged. In 2002 a Canadian Col, I think it was, dropped a Taliban at just under a mile in-a-half. 1.42miles. (I was just reading)..Then in 2009, that record was broken when a British Calvary soldier killed 2, yes 2, Taliban machine gunners at a distance of exactly 1.5miles. A .338 Lapua was used in that one. or 2. But the .50BMG is the sniper round of choice now with rifles like this Bushmaster. There are match grade .50BMG, and at that size, 700-800gr traveling at 2,900ft/sec packing 15,000ft.lb of energy. That's all bidness.
What's way cool, and I'd love to feel it to believe it, but Bushmaster claims a recoil similar to a .243 due to the muzzle brake.

Here's the BA50 Carbine.
