Delayed gas blowback mac10 in 460 rowland

Masterpiece Arms made a semi-auto MAC clone in .460 Rowland for a while.

nyet, Mitch Werbell made a fine gun. No need to change.

Yeah but that's not nearly complex or retarded enough for OP

Do a Glock. Way easier. Makes noguns Jow Forums posters uneasy.

Polymer is garbage.

Seconded

>plastic
>for 460 rowland
>basically a light magnum round
Lol

See?

What?

Drill a hole in the back of the receiver, then weld on a buffer tube housing, and attach a buffer tube for a pistol caliber recoil buffer for some AR15 kit.

Originally, some people did this to slow down the rate of fire on the full auto ones, to make them more viable for subgun matches, but I figure this would also help handle recoil impulse for a high powered blowback gun.
If anything, the setup done correctly should help prevent the bolt and receiver battering each other. You'd still need a weight bolt and spring to make sure the gun stays closed for long enough.

Mitch WerBell didn't make the M10 or M11 guns, he made the silencers under SIONICS. The guns were originally designed by Gordon Ingram, made under MAC and RPB

>fine gun
It's the Hi-Point to Uzi's Glock, so to say.
They work, but they're not *nice* guns.

I don't even like Glocks but stop being such fucking fags, Christ.

There isn't anything stopping you from firing it just blowback all you need is a stronger buffer and a much stronger recoil spring.

See pic been trying different barrels and shit and currently converting it to use uzi magazines since original magazines are too fucking expensive.

The original magazines are also really bad, while Uzi magazines are really good.

Where are you having it converted?

I just realized you bought a semi auto and not a mg. Kinda stupid to convert a semi auto.

Nice.

I'm not OP, but I don't see why not, considering how garbage the original mags actually are.

The pistols which didn't fucking work and which OP should NOT take lessons from?

.

It funny that they told their investors they could replace the M1911A1 with the M10.

How do you like that thing? I've been considering getting a side charging variant by MPA and SBRing it.

Original mags are grease gun mags. How are they bad.

Recoil springs don’t do anything to delay unlocking.

But then I would need to drill a hole in the back of the recoil and buffer assembly in the bolt and attach a rod to the back of the bolt and into the buffer. Then again I’d gain a lot of weight in the bolt like this, not too hard either.
I’ll think about this but I’d really like to maintain the compactness of the Mac-10. I’d be firing this with a buffer tube and brace anyway but I’d have it to be folded as well. This way it’d always need to be on,

They were far better made than MP40/Sten mags, but they had some of the same inherent problems.

Some of the 9mm guns used Sten magazines, which were pretty terrible, and some of them used their own proprietary magazines made out of 'zytel', these magazines have a pretty short shelf life and are known to split down the back from heavy use. There are some steel mags out there which are a lot better, but they're hard to find.
If you have a 9mm gun, converting it to take something like Uzi/Colt or S&W magazines will VASTLY improve reliability and you don't have to worry about them breaking and look for rare NIB replacements.

There ain’t no locking all the guns are simple blowback.
It’s not an SBR it’s an MG.

>Recoil springs don’t do anything to delay unlocking.
They sort of do, actually. There are some guns in 9mm Luger with light slides, but with super strong springs. This works theoretically, but it has a shitload of shortcomings and problems.

So of course, those guns never caught on.

>the tilted stock for full nigger 'aiming'
my fucking sides

You know what I mean.
It doesn’t do anything to delay the movement of the bolt back. At best I’d get case ruptures and at worst a kaboom.

Yeah I imagine not. You need mass in blow back, and I bet those had locked breech faces too.

Colt mags don't work because they're designed for the AR-15 mag catch.

But whats actually wrong with grease gun mags? How are uzi mags better?

UZI mags are reliable as fuck.

M3 magazines are single feed. Which is inherently flawed for full-auto guns.

The one I'm thinking of wasn't locked at all.

I can't remember the name, but it had this thing where you had to disconnect the spring from the slide to be able to manually cycle the action when loading the chamber. The gun worked, but it was difficult to use because the disconnect was fidgety.

Cut a new mag catch. They're otherwise 100% dimensionally the same as Uzi magazines.

Both are double stacked, but Uzi magazines are dual position feed, while M3 mags are single position feed.

You can make single position feed magazines work, and the M3 mags worked pretty damn well considering the era they were made in, but the feed lips wear faster and they're a bitch to load with your hands. They won't wear AS fast as Sten mags, which could wear out extremely fast if you gripped the magwell wrong or bumped the gun against something when shooting, but the feed lips have to be at an extremely precise angle to make sure they still feed right, or they will never feed properly again.
Modern pistols generally tend to have this setup, but at an angle, and at roughly half the capacity, also having the advantage of a lot of modern technology and hindsight.

Uzi mags aren't a cakewalk to load (at least when new), but it's far easier to just press rounds straight down from the top. The lips are also much hardier (unless some conscript putz has been using the thing to open bottles, oy vey).
Now, I'm not about to say someone should travel back in time and yell at Gordon Ingram until he changes his mind, the idea to use M3 mags for the MAC M10 made a lot of sense back in its day, as they were very cheap and plentiful, and were generally still in good shape, but it wasn't without its problems, and from a modern day perspective, converting a 9mm Ingram to take a better magazine makes all the sense in the world.

that's a pistol brace

Not a bad idea. Already cheap buffer tube adapters available. Just need to drill a hole through the receiver and the adapter. Then get a rod of steel(even more weight) and place against the back of the bolt and put it into the buffer tube with the buffer weight and a spring.
You probably wouldn’t be able to use the Mac 10 spring and that would need to be taken out. Also the recoil assembly pad needs to be drilled too.
That rod can also be tungsten, even more weight.

TIME FOR SCHOOL

Uzi magazines are 9mm double feed double stack.
Uzi 45 ACP magazines are single feed single stack.

The only advantage the grease gun magazine has its double feed so it holds 30 rounds in a shorter magazine.

Right, but I wasn't talking about .45ACP Uzi magazines.

Correction double stack*

But the thread is about a 45 cal Mac.

How hard would it be to cut a 1 inch diameter tungsten carbide cylinder?

Bump
