[QUOTE=felix the cat;39013579]I think they were thinking that roller-delayed blowback worked exceptionally well on the MG42, so why shouldn't it work on a battle rifle?[/QUOTE]
the MG42 was roller-locked, not roller delayed. they're not the same at all
roller-locked and roller-delayed are literally the same thing
[QUOTE=felix the cat;39013676]roller-locked and roller-delayed are literally the same thing[/QUOTE]
no they're not
[QUOTE=Kasuga Ayumu;39013428]delayed. that explains even more good god what was H&K thinking?[/QUOTE]
as if that isn't a good successful design...?
[QUOTE=felix the cat;39013676]roller-locked and roller-delayed are literally the same thing[/QUOTE]
No their not. Roller locked has the action locked until the barrel and bolt move recoil a certain distance. Roller delayed is a system they enables blowback action in larger cartridges without a massive heavy bolt or enormous spring
Anyway, Roller delayed blowback is really good if you ask me, I'm surprised no one is designing new guns with it

I'm also not sure what you're saying with that patent

It yanks the casings out so hard is smacks them into the back edge of the ejection port when cycling.

.308 is too violent for blowback no matter what the delay is. roller delayed .308 rifles destroy all the cases that they spit out
that's the patent for the roller lock, and it shows the difference between it and a roller delay
Well that pretty much fucks over any chance at reloading those, I guess :v:
Looking it up, those dents are caused by the brass flinging around and hitting the rifle during ejection. Not the fault of the RD blowback

[QUOTE=ewitwins;39013762]Well that pretty much fucks over any chance at reloading those, I guess :v:[/QUOTE]
Apparently people still reloaded them though
Why the hell would you reload dented brass? Aren't you risking some sort of a breach?
Ignoring the crappy music

You can see the brass strike the gun during ejection here, explaining the damage
Well when you think about it, the G3 was designed for the military, and the military has a total of zero concern for spent brass. They're not reloading it, why would it matter to them that the brass is being chewed up on ejection?
Wow, I never realized the speed at which brass is ejected is so incredible.
that's not what causes the damage, there's a cutout in the chamber that causes it. early prototypes without the cutout, when the gun ejected, it would rip the case heads off the gun
the blowback is too violent
[QUOTE=ewitwins;39013823]Wow, I never realized the speed at which brass is ejected is so incredible.[/QUOTE]
I never realized either until my friend had a go with my bumpfire-stock AK while I was standing next to him. Being peppered in the face with hot brass is NOT fun.

They've pretty much always made them with fluting so that doesn't happen. This damage isn't caused by that

My G3 has sparked a great conversation. I like this.
It is beating the shit out of the brass, that's for sure. I'm just concerned if it can be reloaded with that ding in the side- some are quite nasty.

I wouldn't
if it is indeed the ejection, put a piece of rubber in the ejection port where it hits. that would fix it
So does anyone on here actually have any experience doing a build that requires welding/remilling a receiver and doing all sorts of machine work?
You guys were saying that building a Suomi was one of the easier projects out there (as well as the guys on the Weapons Guild forum), but I take one look at all of those tutorials and get slightly overwhelmed by the lack of a coherent step-by-step guide of any sort.

The assumption I think is that you have the machining skills required
[editline]29th December 2012[/editline]
Thus not needing a stop by step guide
Is there anything [b]like[/b] a step-by-step guide out there? The Suomi is the closest bet I have to an affordable build that won't cost me an arm and a leg, and I don't have the funds to run out and drop a load of cash on an AR or an AK.
you should probably just design your own gun if you want cheap

Actually during range practices collecting brass for reloading is a given, but that could just be us because were so poor haha.

If I remember right, the Suomi has a REALLY thick receiver, so it's easier to weld on without burning through. If you're not experienced with welding on thin metal it's really easy to burn though and in doing so you just eat away at the metal and have to fill the holes with more weld. A little bit of weld is alright but a lot isn't.
The hard part is rewelding the receiver with the right length and without warping it. The receivers themselves should be properly treated already, but the welds will shrink as they cool.
but seriously
wheres my fucking nagant revolver
I've decided I want to get a bullpup in the $2k range. What would you guys choose?
