I'm in the army so I've fired: M9; not really satisfying very light recoil really basic and easy to use. M4; pretty cool but it's only got single shot and burst fire. I've only used burst fire when firing blanks becuase it's a waste of ammo, you can get a boner off of it though. Mossberg 500; pretty cool because it's a freakin' shotgun but the targets for the range are so close almost everyone shoots expert. M320 Grenade launcher: Only ever shot chalk rounds from this baby because I'm stuck in garrison. AT-4: Shot it once before, pretty badass, the explosion will give you a hard-on. M242 Bushmaster chaingun from a Bradley CFV IFV: MOST BADASS SHIT YOU CAN FIRE, GUNPOWDER WILL FILL YOUR NOSTRILS AND YOU WILL WARGASM! I love my 25mm Bradley chaingun. M2 Browning "Ma Deuce" .50: Trust me you'lll get a boner. Mk.19 auto grenade launcher: only shot chalk rounds out of it. M240B LMG: Pretty badass you'll get a boner, it's a bitch to carry on mission though, 38 pounds of suppressive badassness.
