The AK-400 is a prototype Russian assault rifle.
History
The AK-400 is rather famously known for, if it is even known at all, for being the prototype design on which the full-production AK-12 was built on. Very little is known about the history of the AK-400 other than that, as most details of the history of the weapon are practically shrouded in secrecy.
Design Details
The AK-400 is essentially a very heavily modernized AK-74, with new additions such as a folding and telescoping buttstock, Picatinny rails, a redesigned pistol grip which houses the cleaning kit, a redesigned trigger, a two-position gas regulator and a short-stroke gas piston which pushes on a fairly standard AK-patterned bolt among other things.
Variants

Standard assault rifle variant. The AK-400 was developed into the AK-12 and 15.
- RPK-400
Squad automatic weapon variant meant to fill a similar niche that the RPK filled back when it was introduced. The RPK-400 was developed into the RPK-16.
