Gun Porn!

Yep. The Only thing I don't like about it is that barrel is apparently difficult to swap in the field if needed.

Apparently they didn't think you'd need to because it's got some funky air cooled way of not overheating.

Well it wasn't intended to be a QCB weapon. Although an easier replacement in case the barrel ruptures, wears out or otherwise malfunctions might be a good thing.

Garcon:It uses the forced air cooling principle. A few weapons have used it successfully in the past.

^ Such as the earlier mentioned Lewis Gun.

I heard from a guy that it's also self-cleaning.

A lot of guns have self-cleaning gas systems, tell me something new.

Well 'self cleaning'. You actually do need to do periodic cleaning of the gas systems. If you let it get bad enough you either need to dunk the gas system in a solvent tank or replace it. Also they can and do get fouled up especially since it is one of those systems that is usually the hardest to clean in the field. Cleaning the gook out of and off of a gas piston and wiping it dry is a good idea.

Honestly wasn't expecting anybody to take the comment seriously. It was a joke about the M-16.

Oh I got it that is why I didn't respond before tom. I didn't have anything handy.

^^^ True, but a lot of long stroke pistons are much less maintenance intensive than other gas systems. Some of em will clear even mild particulates such as some varieties of fine dust in the tube when they shoot the gas back out. Typically those are very heavy long strokes like that of a Bren gun though.

I forget, is the PKP a long stroke piston?

True the beefier pistons build up is less of an issue. I am not sure if the PKP is a long or short. I think it might be a long stroke piston as it is preferred for MG's in a broad design sense.

The PK's long stroke.

I had a look at the Pecheneg's webpage on wikipedia. There's a bullpup version.

If you use Chrome, it auto translates for you. Looks nice.

A bullpup belt-fed...I think I feel faint...

I don't get it. I thought bullpup meant the magazine was behind everything else. It just looks like they tilted the box and added some grips.

Bull pup designs push the action further back making for a more compact weapon. That is why the magazine is usually further back because the action itself is pushed further back.

So what actually classifies the weapon as a bullpup then? I thought it was having the magazine behind all the other things.

Overall design feature. The chief being the fact the action is usually pushed back further into the weapon behind the trigger group.

That technically makes the 20mm gun on an F-15 a bullpup design if you think about it. The trigger, in the cockpit, is well ahead of the action, in the wing root.

Where is that news paper Taira likes to thwap people with? You know the one that that has carbon boron fibers laced through the paper?

I think it got burned by mistake.

In simplest terms, action is behind the trigger. More specifically the whole chamber and firing system is behind the trigger. Feeding system, firing pin, extractor the whole she-bang. All behind the trigger.

As mentioned it makes for a more compact firearm while still retaining barrel length. A majorly significant advantage compared to traditional designs but using shorter barrels like the M4, G36C/K or AKS-74U.

So downsides then, what are they?

There's always downsides. Surely it's more expensive or something?

They tend to be back heavy which can throw off aim in less experienced shooters in rapid fire and unless you carefully manage it you will likely not have the luxury of a stock mounted recoil mechanism unless you do something clever and compact everything in the back end.

Shooters who are used to traditional layouts have a bit of a hard time adapting due to muscle memory and force of habit. It requires retraining to switch between designs.
