That's not quite correct, even the best heat-resistant polymers well melt long before wood catches on fire (and unlike wood which you could put out, melted plastics will never be the same), wood has better heat resistance, and a good wood grip is actually better then a polymer one, this is also why the plastic grips need that steel heatshield inserted in them, and the wood grips do not. But plastics are much cheaper, much easier to work with, and they have much better environmental resistance, wet, dry, cold, hot, doesen't matter much to plastics, but it can damage wood which will then nee

Good stuff beretta, that should hopefully clear up any confusion about how the gun opperates

Yeah that's my take on it aswell, if the diameter of the piston shaft can be decreased just a bit, then an AEG spring should absolutely work, i see no reason why it woulden't, nothing in the mechanism should prevent it from functioning. The only real question is: Will the piston's shaft still be strong enough if you mill off a bit of it's width? I honestly don't know, which is why i haven't just done it, and have decided to look into alternative solutions first.

The backstop, it's that big and vaguely T-shaped block of steel that's shown below the reciver on all the disassembled pic's, it's mounted to the bottom of the reciver, and it's head reaches up into the bolt-tube through a cutout on the tube's underside. It pretty much fills out the bolt-tube, so the spring is stopped by that at the rear, and since it's part of the reciver and doesen't move, that's what the spring is compressed against when you cock the gun, and it's also the part that traps and releases the piston. So no, it's not really a spring guide at the rear, that's made impossible

It's actually the inner diameter that's interesting here, because unlike an AEG piston, where the spring needs to fit inside, the Zeta's piston needs the spring to fit over the outside of it's shaft. But yeah there are oddball AEG springs, i can tell you that the Realsword spring very nearly fits, because the steel it's made of isen't nearly as thick as the M130 one i have, making the inner diameter larger, so it is possible that there exists some brand of AEG spring that could fit, i just don't know what that brand or type would be..

I don't have my... that measuring tool i just realized i don't know the english name of, for accurately measuring the diameter of an object, freind of mine borrowed some tools for a project he's tinkering with. I'll post it eventually when i get it back, lest someone else can chime in with the answer first. Aye, Mosin's can vary quite a bit in finish, they wheren't all hastilly build, so some of them can be quite nice, but many of the wartime productions can be very crude. As for sighting, having a bayonet attached/detached or folded/unfolded changes how the barrel behaves whe

They are clouse to identical length wise, ergo i belive it would be no problem to use AEG springs if one where to modify the piston, but of course, i haven't actually done it yet, so i won't make any promises. From top to bottom: Zeta-lab spring. M130 AEG spring from an "Action" V3 gearbox. Realsword M90 AEG spring. The piston and it's shaft are one machined part, and the tail section is inserted from the back, and locked in place by a pin that goes through the piston shaft and the tail end (you can see the pin as a black dot on the pictures of the piston in the review).

Tanaka Kar-98K, Hexagon PPSh-41, Zeta-Lab Mosin Nagant M44:

It finally happened, there's now a Mosin Nagant replica worth looking at, the Zeta-Lab Mosin Nagant M44 Carbine, which retails at aprox $370 USD. I'll kick off this review by adressing what is undoubtedly the first question most people have, namely: Is it a clone of that terribly expensive KTW model that wasen't very good? Well it is and it isen't, Zeta obviously used the KTW as a template, and have copied several things including the magazine system, but it is not a straight clone, they have made some vital improvements to the design, and that's reason enough to give it a second l

Over the weekend i got my hands on a RealSword T-56 pistol grip, and decided to have a stab at mounting it on my LCT AKMS, it took some filing and grinding, but the bugger got on there! it's not a perfect fit, there's a little gap just behind the grip, but it looks quite decent other than that: Or what say you? keep the wood or go back to the ABS?

Looks like an M38 Carbine, so most likely RealSteel.

Have they cleared prototype stage yet? last i heard anything they where still experimentals.

Yup, and just to clear up any confusion, here's how all the modern AK's stack up: Name -- Size -- Caliber AK-74M - Full - 5.45x39 AK-101 - Full - 5.56x45 (NATO) AK-102 - Carbine - 5.56x45 (NATO) AK-103 - Full - 7.62x39 AK-104 - Carbine - 7.62x39 AK-105 - Carbine - 5.45x39

104 actually, but yeah, thats the good thing about the 100/74M series, just a change of mag and you have a different gun

You mean the little fellow with the coathanger stock? that's an LCT AIMS kit with some different furniture on it (LCT "red" pistol grip, RS AKM wood, LCT ventilated steel upper on an AKM gastube).
