I don't really understand the use of the iconic selector switch in the Mod 2023 version as it doesn't seem to have any selector function except perhaps keeping out some dust and debris? They do mention a "curtain" - but why not just extend the top cover?
When the rifle is on safe it acts as a dust cover, but when firing that slot that it closes needs to be kept open to allow the cocking handle to reciprocate.
If you fill the slot with an extended top cover you would need to modify the cocking handle and how it works which is quite a change for aesthetics.
I personally liked the way the SLR system worked but in an emergency I suspect your average Russian will reach to the right hand side and expect a cocking handle that is fixed to the bolt carrier so you would need an amazing reason to really change that.
The ADS has a cocking handle that can flip left or right and sticks straight ahead when not in use which I think it clever but have never actually tried it myself.
They should honestly just adopt a version of the AK tht has the shturmgewere style upper lower receiver arrangement with the upper rail being a thick piece of machined aluminium bolted and pinned directly to the trunnion
A rather radical change considering the length of the receiver. The old side latch mount for older scopes worked fine... an enlarged version of that moved to the top of the receiver instead of just beside running the full length of the receiver should make it work just fine for any existing AK with the part in front of the top cover all in rails too.
Some sort of bridge connection to the front and top rail to make it more solid shouldn't be too hard.
The whole top cover rail idea was always deeply flawed and will never be as accurate as a rigid, non removable machined arrangement. If they really have to keep the traditional Russian style top cover then they should move back to side rails and milled receivers.
These are assault rifles firing assault rifle cartridges which means if you can hit targets out beyond 400m then good for you but the likely damage is going to be equivalent to getting hit by 22 rim fire ammo most of the time.
Soldiers shouldn't be aiming for head shots at 600m, a torso hit out to 400m is far beyond what they will be needing most of the time.
If you have guys that want to hit further then give them the SVD or it new replacement.
Most guys wont even see targets at that distance, and if they do then that is what SVDs and PKMs and RPKs are in the unit for.
I can only guess that double shot sequence was a spinn off from Abakan project?
The idea of a rapid burst of a few rounds, whether it is two or three shots has been a popular thing, but from what I have read is that one of the main reasons US soldiers like the shorter M4 carbine over the M16 rifle of the newer types is because the M4 has single fire and full auto options while the newer M16 has single shot and three round burst options.
Obviously the M4 is also more compact and lighter too, but it sounded like a lot of soldiers preferred the smaller lighter rifle because it was full auto capable.
2 round was essential to the Abakan, and the whole mechanism of balancing exhaust gases to minimize recoil of the second round.
As finally new models haven't received the feature, and the demand by MoD aged longer - they have finally cancel that. This is my understanding of things.
The Abakan had a recoiling barrel and the two shots were fired during one recoil impulse to try to get them on the same trajectory... they were never going to go through the same hole in a flak jacket or anything, but the second shot was supposed to land within a 80 or 90 mm if the first round so a moving target the second shot would increase the chance of getting at least one hit and for a still target you increase your lethality by putting two holes into them instead of one.
The much lower rate of fire of the AK-12 would mean it probably wouldn't work so well though the very low recoil of the round could allow both rounds to be on target, it seems the added complication to make it work... some sort of two position ratchet system, wasn't worth the effort.
I seem to remember on the M16 there was a ratchet mechanism that counted the shots so if you fired off most of your ammo and had one round in your rifle it would fire the one round but the second round would be an empty chamber, so replacing the mag when you pulled the trigger expecting a three round burst only one shot would fire to reset the ratchet again.
It was tricky to work out how many would fire... a distraction... perhaps a reset when you removed the mag maybe... I don't know...
The burst fire options is nice to have on paper but it is apparent that it comes with some reliability issues. Not so nice when you're under fire!
I do remember when the British soldiers finally got to test the worlds best assault rifle in the desert (it was going to shine because the long barrel gave it excellent accuracy and performance over flat open terrain) and they found that it was actually more reliable on full auto than on single shot... which I thought was a bit ironic.
But the AK-107did pretty much the same...for a lot less.
The balanced recoil mechanism is probably more complex than most soldiers are wanting in a rifle, most soldiers probably just want single shot and full auto and they can train to get the bursts they need...
The complication needed to get a two round burst will come at a cost in weight and price and complication, so if it isn't being used then it is a good thing to get rid of it.
With the Abakan the first two rounds were fired at about 1,800 rpm but the third and later shots in a full auto burst were at 600rpm.
With proper training and supported holding of the rifle even in full auto the rifle does not appear to jump all over the place anyway.
Most accurate is always going to be single shot and its low recoil means you can observe the effect and follow up with further shots to finish off the target or to correct to get hits.
I could see a three round burst being useful for a light machine gun, but their new light machine gun doesn't even seem to have a single shot option.
The KORD assault rifle seems to have a burst fire option too, I wonder if upgrades will keep that feature or not.
It does use a balanced recoil mechanism... I wonder how it compares with its higher rate of fire (900rpm)... getting a 2 to 3 round burst with a full auto trigger on an AK-12 might be easy, whereas with the Kord 5.45 it might be firing too many rounds in a burst so a burst mode for firing 3 rounds only might make more sense.
