   Max Popenker with new civilian revolver-carbines based on RSh-12 assault revolver, from Army 2021.

   MTs-569 on top, in 12.7x55 (5 shots), MTs-570 below, in 9x39 (6 shots). 12.7 is 3kJ bullet from this carbine, lol.

   Max claimed that recoil was not discomforting on 12.7, and on 9x39 he called it "toy-like". Reason is that those revolvers have ability of whole upper part of gun to move under recoil forces.

   Also:

   When rolling back, only the inner spring of the firing mechanism is cocked, acting in parallel with the trigger spring, which makes it possible to reduce the force on the trigger when firing self-cocking.

   Obturation of the joint of the front end of the drum (firing chamber) and the breech of the barrel is carried out using special insert sleeves located in the front of each chamber, similar to aircraft revolving cannons. When fired, the sleeve is pushed forward, blocking the gap between the barrel  and the drum.

   AM-17 prototype first look from user side.

   Pluses - weight (2.7kg with red dot), big ass monolitic rail on top, ambi selectors, adj. stock that folds to the right and doesn't interfere with ejection port, use of AK flap for magazine release (muscle memory, training), ability to eat all mags for AKS-74U, ability to put charging handle on left or right side, ability to partially disassembly without messing with optics/zero of sights. SVD-alike short piston system makes it run much cleaner. 

   Negatives - barrel doesn't accept commercial/aftermarket suppressors and muzzle devices, standart muzzle device doesn't work well as compensator or flash hider, no suppressor in a kit of this gun. Main negative element of this gun is recoil, it "kicks", and this kick is somewhat comparable to 7.62x39.

   ADS in Lazarev's hands.

 

   Interesting bit - long rail version are used in this video. MoD RF footage of firing ADS and older "underwater" guns umm... under water is also sprinkled here and there in this video.

 

   Gas regulator have "air" and "water" settings. "Underwater" bullets also works in the air. Dioptrical iron sights are build-in into the rail. Grenade launcher-rifle selector is located on the left side of the gun. Grenade launcher have separate trigger, so i guess this selector was made according to MoD requirements. GL trigger have an interesting additional "safety" feature (on 10:30 mark you can see it) - a circle piece that you push away with a finger.

   Video also shows a close up how spent casing ejection works and it is a bit unusual (around 8 minute 30 seconds mark). Spent cases are pushed into a "holder" above pistol grip on right side, facing forward-ish and only ejected after next shot or bolt carrier moved by hand. This was done according to MoD requirements.

   Charging handle can be easily moved from to other side of the gun by simply rotating it (10:52), and looks like it is even faster and easier than on ARX, lol.

These are stupid games. Potentially very stupid games. I approve of them, but I will not play them.

Yeah, those guns on video are getting to "nearly as dangerous for user as for target" area.

 

Is this normal for FGC-9? Maybe they should use different ammo type?

It's normal for any design like that. Most normal 9mm blowbacks are susceptible to out of battery firings. What makes it worse is the printed receiver.

About ammunition for 7.62x54R chambered Soviet/Russian sniper rifles.

SVD with 7N1:

Quote

Muzzle velocity of this load is approximately 2,723 fps and average group size runs between 1 and 1.5 MOA depending upon the individual lot of ammunition and the condition of the rifle. Our colleague Chris Pappas put five rounds of 7N1 into 1.9 inches at 200 yards with his SVD.

 

7.62x54mmR 200-grain EXTRA Match

Quote

This load is well-capable of sub-MOA performance in a modern target rifle and averaged 1.2 inches at 2,571 fps out of my old M1891/30 PE Sniper.

A few FN Evolys have been delivered to French special forces (in both 5,56 and 7,62).

Probably just for testing purposes for now, like the British army.

While concerns regarding sustained fire capability are important for the regular army, it is probably less so for SF (which would likely rank the reduced weight higher on the priority list).
