AK74-U

The MEC Carbine comes with a neat camouflage, sadly, the colour can only be described as 'dinner gone wrong'. Don't let this guns sick-like features put you off though, it's more powerful than the M4, and just about as accurate. It still has the two firing modes: Auto and Semi-Auto, it also has 30 bullets.

Wikipedia says the following:

The AKS-74U is an assault rifle designed in the Soviet Union that was in production from the early 1980s until circa 1991. The AKS-74U ("U" for "Укороченный"/"Ukorochennyj" [shortened]) was developed in the late 1970s from the AKS-74, a shortened variant of the AK-74. The earliest known models were produced and dated by the Izmash and Tula Arsenals beginning in 1981. The AKS-74U is the size of, and has the effective range of, a submachine gun. Only a few parts are interchangeable with the AK74, although it does utilize the same 5.45 mm ammunition. A notable distinguishing feature is the conical gas expansion chamber developed to control recoil and muzzle flash as well as to facilitate cycling of the weapon given the shorter barrel.

The tactics remain about the same, but there are a few precautions to take.

1. Do take in mind that this gun is less accurate, and you really should be semi-auto-ing anything further away than 10 metres, or you'll just have a lot of bullet holes in you and the wall behind the enemy.

2. Never shoot this gun when moving, unless prone. the same result as above will happen.

3. Enjoy that extra power in the gun, though the differ enc is minuscule, the gun definitely makes most people wielding it more confident (or sick).
