So rather than thinking of the weapon as a strange or long, tech path, it's actually an easier tech path given the requirements (aside from the special ammo it used).
The Nagant M1895 revolver is one of the few that an armorer might be able to mount a silencer on. With a revolver, you don't have failure to feed problems, the powder charge has no direct action on the loading cycle.

And this is probably a more important feature than any of the things that I have mentioned (I wish I had thought of it haha!).
When this situation occurs, you can cycle the next round faster (and without taking your hands from their positions on the weapon) with a revolver rifle than you can with a semi-auto or even bolt-action rifle - and there's less chance of shifting the point of aim when you do so.

There was also a suppressed S&W 625 made for a German police unit that used a clamshell covering over the cylinder to contain the gap gases. The PSDR 3 used a subsonic .45 ACP round and a large suppressor to get the sound down to 90 dB.

The point being, that supressing a revolver can be done. And with the idea being to produce a rapid, single shot, supressed weapon that retains the cases, putting a metal cage over the ejection port of a semi-auto would likely cause a distinctive noise as the shell hit the cage. There's also the problem of just how big do you make the cage to allow it to effectively capture all the cases without filling up to the point of jamming the action and how unwieldy does that make the weapon?
Yeah, a cage/bag over the ejection port was one of the other ideas I had thought of, but it tends to be unwieldy (as you shoot, you get more weight hanging off one side of the gun), it's not truly silent (even with a canvas bag, you'll have brass hitting brass), and if you have any problem with ejection, it's much slower and harder to clear.

Another idea was a forward-ejecting system (similar to Kel-Tec's RFB) with a manually locked tube, but that would be severely limited in capacity, and if it wasn't cleared, it could do nasty things to the rifle's innards.

Have you considered just using the sub sonic piston type ammunition with a silenced revolver? Not that it may need a can with piston ammo.

Lever action rifles are also very good for silencing. .44 special out of .44 mag slowed to under 1150 fps is a option as you are able to keep large grain (mass) bullets to retain stopping power.

The Nagant is designed to cam the cylinder forward to mate with the barrel to retain all the pressure from the powder charge. The idea was that the poor quality control of the Czar's arsenals gun powder would be overcome this way. There isn't any cylinder blow by.

I doubt the brass hitting brass is much louder than the revolver's hammer hitting the base of the firing pin. In a rifle configuration with a bipod, a cage with fired casings is unlikely to unbalance the weapon. After all, many successful SMGs had side-mounted magazines that were more unweildy.

Ooh perfect. Another wonderful turret/body hybrid. I always thought this type of thing would be rather common.

It was nice that even with only parts for the automatic rifle present, Ian was able to give viewers some idea as to how the other weapons were assembled using the receiver.

I agree. I think that by 1999-2002, turrets and chassis would be mixed and matched, depending upon the support available, compatibility, and what was available and working.

Indeed. And he alludes to future videos, I'm so excited.

So apparently there's a shop where I used to live that makes semi auto conversions and semi auto reproductions of ww2 machine guns. and apparently he took the rp-46/dpm conversion and made it better.

There is REAL promise in the system. To reduce recoil, that 105mm operates under the concept of "constant recoil." The barrel is pushed forward just before firing so that it has farther to travel before it hits the recoil stop (and thus transmitting the recoil to the carriage). The barrel then arrests just short of maximum travel so it never contacts the stop. This lightens the "felt recoil" of the weapon. The reduction can be quite significant. The same system is used in the newest version of the AA12 Assault Shotgun as well.

This totally looks like something from the G.I. Joe toy line of the mid-1980s, and would make an interesting, if unconventional PC vehicle for T2K. I'm kind of surprised it didn't make the cut for the v1-2.2 U.S. Army Vehicle Guides.

Somewhere I've got a folder with pictures of the 8x8 VADS system in...over at the AFV forums there was some discussion on it. The vehicle itself was abandoned (as in, dropped and no longer considered for procurement) and the lone example is sitting in someone's yard (minus the gun and supporting turret).

One vehicle that I don't think we've mentioned before is the Bobcat APC.
This was a 1950s Canadian design that, had the concept been pursued, might have seen the Canadians getting the leap on the UK and the US in APC design (and sales).

When I first learnt about it, none of the following sites even mentioned the Bobcat let alone had any information about it. I read about it in an obscure book on armoured vehicles (by a German author, translated into English).

Anyway, the Bobcat: -
