Wish plate carrier came in

While you could weld in sections to make a cetme style action longer, you would also need a new bolt head in the least, and a new barrel

Real nigga hours, converting a normal firearm down to a black powder

A heavier set of rollers is a given

Get in VC fags

Already have the barrel, and the bolt head could be modified if what I remember of the CETME/G3 bolt is true.

Which is all proprietary tooling

Do not ream out a 7.62 bolt head

The cartridges base dimensions are too far to modify

It's... actually 0.05mm shorter on the Masuer

That's not the problem, it's the engagement

Thickness is the same too

Also if you're going to even try this get good at welding

This is more of a "lmao I want to see if I can"

Than actually using it

Put a Yugo Mg barrel in it

And turn it down for an hk21 adjustable gas block

Fucking frankengun

gonna be great

Wait what the fuck am I doing.

If I actually wanted to make this for serious I'd just make the entire thing from scratch

Just put an mg42 bolt in it

MG42 bolt on a rifle why god

That's the actually retarded size roller action you'd need to handle 8mm

I mean you could

With a fixed stock

Just do what the 42 did and have the recoil spring go basically all the way down it

For real though, the fg42 bolt would be less retarded

But still pretty retarded

The FG42 bolt is weird tho

It's the smallest you can get an 8mm

Because it's meant for full/semi toggle

Smg guns makes them

If you shit gold that is

Yeah but again, side loading bolt designed to switch from open to closed bolt on full and semi respectively

It's not bad but it's purpose built

Unless you get a weird SAW box mag that feeds from the side but attaches and hangs like a normal magazine

Maybe you should just not design anything ever

Dabble and [dab] in Solidworks

I designed a 3d printable Skorpion lower that uses ar15 parts
