A shoulder mounted rifle?

Probably a reference to the anti material sniper rifle from Metal Gear Solid 4

It's a Barrett M82A2 bullpup rifle, an attempt to shorten the overall length of the M82 design and make it capable of being fired from offhand positions. The M82A2 didn't garner much market interest and production was canceled.

This is definitely a blunt MGS4 reference.

It is. Wearable computer + AM Rifle? The only awesome part of the end of the game.
