What do you get when you cross an AK-47 with an M16?
The US Special Forces have been testing this out in Afghanistan. It’s similar to the M4 rifle, but instead of firing the usual 5.56mm round, it fires a 7.62mm AK round using a standard AK mag. The main advantage being if they are a on a long rang patrol, they can replenish using the local variety of AK ammunition while using a rifle they are familiar with and which can use all the standard attachments which come with the M16/M4 family of assault rifles.
