AR-10

An AR platform rifle in the .308 caliber. Far more powerful than the standard .223 round, the .308 is suitable for taking large game at far distances. If an AK47 is a chopper, a .308 M.B.R. is a fucking disintegrator.

Billy: Holy dog shit, that AR-10 just chopped that dude with the bullet proof vest in half!
Timmy: I know, I can't wait to get a .308 mbr so I can fuck shit up too!

The Narrator's weapon of choice.

If I were you, I'd be very careful who you show that to. Because the person that wrote that is dangerous. And you never know when this button-down Oxford cloth psycho might come to work with an armalite ar-10 carbine gas-powered semi-automatic weapon stocking from office to office pumping round after around into co-workers. It could be someone you've known for years. Someone very, very close to you.
