The current world record for .22s is only about 2300 ft lbs. Step up to 6mm and the record was 3500lbs....from the 243 H&H magnum.   The main proble  would be throat wear. Thats why i think you could add tiny bore-riding fins onto the bearing surface of a .22. Briging it up to 6mm...

With polygonal or radial rifling, the fins might be viable.

So moved the controls back and add a 20 cm telescoping butt. all the issues with a bullpup solved.

The way the control group is attached to the barrel, it looks to me like the controls cannot be moved back even 1 cm, let alone 20.  https://youtu.be/J5x_clmnUjo?t=30

I've always really wanted one. 16" bbl and almost 21" length sounds utterly awesome!

After seeing Max's video of the internals you'd definitely need to do very high quality stampings and CNC welding for many of the parts just because of how the mechanism is. 

I think it would be hard to impossible to do it without lots of stampings and precision welds, at least if you want a reasonable weight of end product.

It's a very cool design and I'd personally treasure a repro beyond any other gun I could possibly get!

It'd probably cost $10k each these days though lol.

The LOP looks pretty reasonable to me tbh.

A lot of people seem to think the tkb-022pm is bigger than it is for some reason but the gun is quite tiny. Here's two pictures which should help. It appears to come to a little past the crook of the one guy's elbow in the first pic.

Seems like the ACR is almost as length efficient. Which do u think would be most reliable and which would work best with CT ammo

I looked at a good side view of the gun, and compared the LoP with the length of the magazine (2.62 in).

As best I could measure it, the LoP is about 15 inches, which is typical for a bullpup, and much too long.

You're proposing improving a bullpup by making it less of a bullpup.  Fixing all of a bullpup's problems involves making it not a bullpup anymore...not an uncommon approach to the problem these days, actually.

Not at all.  What Red72 proposed would reconfigure the TKP 022 so it would be similar to typical bullpup rifles, with butt extending behind the magazine, and pistol grip closer to the magazine.  However, due to the gun's construction, the proposed modifications do not appear to be feasible.

As it is, the TKB 022 is not so much a bullpup rifle, as it is more an "arm gun" like the Colt IMP.

well, the guy holding the TKB-022PM on that photo is me, so I can tell ya it's not an 'arm' gun, as it is a bt too long for that role and it's balance too rearward even with the empty mag

add almot .5 kg worth of ammo and it will be terribly misbalanced to the rear

and clearing malfunction on this one... not something i can envision as a nice experience.

Thanks, Max.  I figured it was probably you in the photo.
