Let's all take a trip back to the late 1970s and early 1980s.  This was the time of punk.  This was the time of despair.   Punk was all about minimalism; strip everything down to a few chords, wear

Stechkin's Abakan (TKB-0146). https://www.kalashnikov.ru/abakan-stechkina-avtomat-stechkina-tkb-0146/        Bullpup, system of "recoil impulse shifted in time", 2-stage

So what, my 5.56 rounds are groundbreaking too if I shoot the dirt.

   Kalashnikov's SR1 is kind of bad. Problems with controls, ergonomics, magwell and so on. Low quality of some smaller details also noted. Failures to feed, impossible to press some buttons, it even managed to damage one of mags. Those and other problems are making SR1 questinable weapon at best.

Lol.

 

My Saiga .223 with an AR-15 magwell adapter is better than that thing.

What really gets me is how similar their production SR1 configuration really is to the Canis Design Group m4 to AK one piece conversion assembly through the stock interface, grip, and magwell right down to the rounded nub forward of the well.

 

Edit: Yeah I know there's only so many possible and somewhat economical to manufacture ways to do such an assembly, but it's still pretty disturbingly close.

Got to handle the MG 3. Boi RIP my shoulder.
It really lets you know its age.

You really gotta manhandle it.

 

And what are those ergonomics everyone is talking about?
You want to shoot it in any other position than prone? Oh my bad not possible.

 

Night sights what are those?
If its dark you stop shooting.

 

What? You want to conceal your position?
Never heard about this "Flash hider" thingy.

 

Really cant wait to handle the MG5 or MG4.

I don't have an MG-3, but I do have most of an MG-42 nearby for study.

I do wonder whether adding a flash hider would affect rate of fire.  Presumably any sort of flash hider would also have to double as a booster.  I think I vaguely recall reading about the Nazis looking at adding a suppressor.  But since the suppressor would be fixed to the gun and not cool off during barrel changes, it would have to be a very tough suppressor indeed.

Do MG-4 and MG-5 have provisions for single shots?

On MG4/5 no but the rate of fire is low enough to squeeze singles of.
Also you need the recoil booster so its extracts the casings.

If you look into it it tries to capture the gasses to press the barrel backwards to unlock the bolt.
There is a sort of flash hider in the booster but it directs the flash forward.

You can try to cut down the rate of fire if you make the bolt heavier and use other return springs. There is a 650g Bolt for 1100RPM and a 900g for 800RPM

      There are many who feel that the 5.56 NATO is a superlative rifle round. Much has been said about larger alternatives to 5.56, such as various 6.5mm and 6.8mm rounds among others. Less has been said about smaller rounds. Off the top of my head, I can recall that there was a German 4.6x36mm round, used in the HK36, and the British 4.85x49mm round. Neither of these rounds managed to gain widespread acceptance. My knowledge of the voodoo that is ballistics is somewhat limited, so I'm uncertain as to whether these failures were caused by flaws with the rounds themselves, or because they were below some lower limit of effective bullet size, beyond which performance decreases rapidly. Could we see a resurgence of these concepts in the future, or do they represent an evolutionary dead-end?
