It's just as reliable as the AK, though with a lot more power per shot. It's also much more accurate and has much better range, though no automatic fire of any kind. Oh, and there's <url=http://7.62x54r.net/MosinID/MosinHumor.htm>this page.

Modernized version of the AK-47, the AK-103 fires the same 7.62x39mm round, with more comfort, more accuracy, slightly better range and less recoil.

The Ingram MAC-10 submachine gun is one of my favorite compact weapons when chambered in .45 ACP. It packs a lot of power into a small package and is a good weapon to use within 300m of your target. It also features a unique, highly effective sound suppressor.

The AA-12 automatic shotgun is, well...an automatic freaking shotgun. That can shoot freaking grenade rounds. This thing will tear anything in your way to shreds.
<spoiler=Five-seveN armor-piercing handgun>http://www.wired.com/images_blogs/dangerroom/2009/11/800px-five-seven_usg.jpg
The FN Five-seveN is special because it uses the same armor-piercing rounds as the P90...and the mag has 10, 20, or 30 of these babies. This gun kicks ass.
