Flare gun with steel barrel (still in progress.)

I’m gonna reinforce 80 percent of the flare gun with steel plates, it’s gonna fire 22 wmr, with a chamber reducer, might change it to look like a Star Wars blaster or something.

looks good but the frame will still crack, You have to hold the barrel tight every time you shoot it. Even then it wont last that long maybe 100- 500 rounds of .22lr

It’s still gonna shoot flares, just wanted a metal barrel for looks lol
Main-Pollution-3678@reddit
I say fuck it and put a metal breach and some reinforcement so you can shoot 12 gauge

I've done this by machining an insert for a steel ww2 flare gun. It still broke in half. Was fun for about 10 rds

If ur already making it metal. Why not just rebuild the whole gun into metal. But for 22 magnum thatll work
Select_Room_3881@reddit (OP)
It’s a little tricky with the internals, I don’t have the tools and precision to do that, so other best option is to shield the thing with metal so it don’t blow up,
HomemadeHardware444@reddit
Itll handle 22 magnum with what ur doing tho yea
Select_Room_3881@reddit (OP)
Tricky part is the breech
sunset_barrelroll@reddit
Maybe add steel in front of the plastic breach and cut down the chamber to make up for the thickness?
Select_Room_3881@reddit (OP)
I’ve thought of that but how would I keep the breech there? Nuts and bolts aren’t an option the plastic is too thin, the breech there will handle 22lr idk about 22wmr or if there’s any difference,
Somebodysomeone_926@reddit
If you ditched the flare gun but wanted a single shot a rolling block design should be fairly simple.
sunset_barrelroll@reddit
Maybe two part epoxy, could grind out the plastic breech and replace it instead of stacking.
Could also grind the plastic breech and build a breech with a saddle to attach mechanically to the frame.

Right I forgot about JB weld lol, I’ve used it before on my very first firearm build, I used aluminum tubing and a air rifle barrel drilled into a 22 barrel 😭 now I just need a longer firing pin, I’ll try it, currently very rainy rn I’ll update when I’m finished with it

Shouldn't be too hard to remake the whole hammer with hand tools if you have the patience
Select_Room_3881@reddit (OP)
Yep it’s very simple, I’ve looked at professor parabellums derringer designs and this flare gun design is so much simpler, idk, I just never could finish making a hammer and trigger pistol, always did bolt and spring in a bigger tube type pistols.
TacTurtle@reddit
You would gut the existing frame and make a new one out of steel plates that stack together just like the JACO Derringer or Western diys or a Cobray
Select_Room_3881@reddit (OP)
That would definitely work, but I’m trying to convert a flare gun into a 22wmr derringer not make a 22 wmr derringer that happens to be based off a flare gun,

Czech 26.5mm flare guns are the goat of doing stupid shit. We bought dozens of them when Big 5 was basically giving them away 20 years ago. Reload the spent cartridges with 50gr of FFF and a 10gr kicker of Bullseye and you'll swear your thumb touched your forearm when you fired it. I would always shoot them with my off hand inside a leather work glove just in case.
Select_Room_3881@reddit (OP)
How much were they?
Simple-Purpose-899@reddit
Like $40 with the full kit, bag, and a box of assorted flares. They were superior the German ones, because the Czech ones have a forged steel frame that would last a half dozen shots or more before they would stretch out and be a little sketchy.
Select_Room_3881@reddit (OP)
Man I wish they still have them that cheap I got this for $30 off eBay 😭
TheShadowuFear@reddit
Full metal flare guns are $150 plus now. Runaway subcal makes inserts to fire live ammo out of them
generictimemachine@reddit
Well, $40 in 20 years ago dollars is $80-120 in 2024 dollars, depending on commodity.

Flare gun with a steel barrel… so a gun?
Select_Room_3881@reddit (OP)
Yeah, never said it wasn’t a gun.

I remember sinking a piece of 5/16" brake line I had jammed a. 22lr barrel liner into into bondo and making an improvised .22 out of one of these as a kid. It was actually pretty accurate given the barrel liner- I left a portion of an inch spaced at the bottom of the brake line and the step from 5/16" to whatever the barrel liner was was subtle enough to act like a chamber shoulder
