I cant own guns yet so all i know about guns comes from airsoft, im a sniper in airsoft and my favorite gun isn't a sniper rifle, its a G36k. I love them i would use one(in airsoft of course) but i have already invested alot of money in sniping, its fun, and im known around my airsoft field for kicking a$$ w/ my rifle.
.50 Cal Desert Eagle Here is a modded one. I own one, it's just not modded heavily. Mine is closer to this. Except the laser doesn't look exactly like that. I would like to own an MP5. I'm more into pistols though. And guns you can actually get your hands on.
AA12 Automatic Shotgun gas operated air cooled open bolt magazine/drum fed 360 rpm counter-recoil fires single-shot or fully automatic only problem is its only available to military and law enforcement
everyone loves the desert eagle. so equally, i do too. also, i know its french, but the FAMAS is pretty sweet as well. and of course, the barrett - .50 cal anti-tank sniper rifle. i think i can manage 5 grand... http://www.barrettrifles.com/rifle_95.aspx
From the compensator and twenty-round magazine, I want to say an M-16 A1 with an M-203 grenade launcher attached. It could be an A2, however, but it's a movie gun to start with, so even if it's an A2, it would still be fully automatic (as it is in the movie), though the A2 is safe/------/three-round burst.
