I could probably do it myself, I know the mechanics of an M1 A1 Abrams, just need the materials.

Hot shit, a lazer! Those things are hard to get a hold of, mostly just because the batteries have to be fucking huge. I'm usually more fond of conventional 'jam a rocket or a clip in and you're set to go' warfare, though. And there's nothing quite like the feel of a fully loaded magnum, all six shells spinning...

Though I had a fucking fantastic little flamethrower keychain back at home, too. Fully loaded and worked 100 percent!
