I can give you pictures of an actual bolt for the last 2, idk if ill be able to find technical drawings, blueprints, etc tho

for the Mauser action specifically

this will do

I want to build a functional one

Flamethrower "pistol"

Any ideas and tips?

I want it to actually work but it's mainly for memes

You probably couldn't

The tank would be so small it would be a giant lighter

Well that's why I said "pistol"

It would have to be upscale

@RoflTank I need your autism-I mean specialty

In building dumb shit that actually works

If you want to build a flame thrower you'd wanna do this

The ones you posted are "Inferno" pistols, essentially the Pistol variant of the Melta

@Magos Squid "The Life Raft" I got u fam. A hand-flamer is pretty piss-easy, you can run a tube up your sleeve to a napalm reservoir rather than pressurizing a can of fuel, and then dress up a propane tank as the fuel can to run your burner.

Now the only problem is range

What are you looking for?

Assuming we're using something close to napalm

Thankfully we can use the bulk of the pistol for a pressurizing pump

Probably something CO2 based since that'd cool, compress, and be easily replaced on the fly while staying relatively compact.

~~Flamers are 8", which is like 2/3 of effective pistol range~~

Hmmm, effective pistol range

25 yards

or so

That's gonna be a stretch

22m in real people units.

Would CO2 work as a stabilizer within the weapon? Keeping the fuel from igniting as easily?

Diesel napalm is stable enough

Because napalm reacts with oxygen right

God no

Nope

Oh ok I'm thinking of something else

I mean you could probably dope it with aluminum powder or something

But that'd be kinda stupid

Yeah, that wouldn't work

So anyway, we're looking at 14m for a hand unit
