AK-74
A Russian assault rifle first produced in 1974, hence the name AK-74. Basically a refined AK-47 made to fire the 5.45x39mm, an obviouis nod to the NATO 5.56x45 round. Has one variant, the AK-74u.
The Russian military used the AK-74, I woulden't be surprised if they still have a few circulating around the army.
Get the AK-74 mug.
