Who said it was going to be revolutionary?
This is not the rifle equivalent of Armata or PAK FA or PAK DA.
This is an extreme upgrade of the existing system designed to take care of all its obvious flaws and problems to make the best of what they have without a complete redesign from scratch.
This is a T-90AM or Su-35/Mig-35 or a Tu-22M3M/Tu-160M/Tu-95MS16M.
It has not turned into an AR, but it has taken some western features that make it more useful, but kept the things that made the AK what it is.
Complaints about the AK have been short iron sight base, lack of a peep iron sight, difficult to fit optics to, no bolt hold open option, controls on the wrong side of the gun and not ambidextrous, folding stock not adjustible in length for when wearing body armour, hard to put tacticrap on...
Not only have they fixed all that but they also added rifle grenade launcher capability and compatibility with all existing NATO standard rifle grenades, they have added a three round burst capability, they have looked at soldiers in the field taping two 30 round mags together and they have developed a 60 round quad stack mag that is no longer than the existing 30 round mag but they don't have to turn it around after 30 shots fired.
They have rails for all sorts of tacticrap but without ruining the front grip for holding the weapon.
They have altered the rifling of the weapon to improve accuracy.
I would say this rifle is now better than an M4 or M16.
It retains the reliability advantage by keeping the mechanism, but adds all the user friendly features of the western rifles with the added advantage of a better placed cocking handle you don't need to take your cheek off the stock to operate.
Safety and fire controls are conveniently located and the peep sight base is much longer than either US weapon.
More importantly the round this rifle fires retains its lethality at any impact velocity so it is not range limited to about 200m like the 5.56mm.
Of course this is one entry, and the military has not even committed to a new rifle yet and might wait for the new designs created from scratch that will represent modular construction and may have calibre kits so a light rifle can have extra barrels and bolts and magazines in light calibres... or perhaps they might take it a step further and have a base rear end with a range of light and heavy uppers so you can have everything from a SMG to a belt fed machine gun and everything in between...
These from scratch rifles will probably start appearing after 2015, so the AK-12 from Kalashnikov... and possibly a similar rifle based on the AK-107 with a balanced recoil mechanism so the Army can choose between the two... to see if they think the complication and extra cost is worth it.
They will also have the ADS from KBP and no doubt a rifle from Kovrov (AEK) and also likely Nikonov has not been sleeping all this time either, so an improvement on the An-94 can be expected too.
From the thread on the VDV reequipping it seems the VDV are getting new underwater rifles and that means ADS. If they have accepted it into service then we can assume the Russian Naval Infantry will be adopting it too.
The question is, will they adopt it as their standard rifle, or just as a specialist weapon?
In 5.45mm standard ammo it is supposed to be effective out to 600m, which is very impressive if true.
