But mommy brings chicken nuggies down to my super-secret gat-lab. Your analogy makes no sense!

Seriously though, thanks for trying to spread the good word to the window lickers.

Polymaker has an issue with consistency in their website, database, and storefront.

https://us.polymaker.com/products/fiberon-pa6-cf20

Here you will find the current recommendation which is 100c for 10h.(Anealing at 100 for 16h)

Think of it like chicken. It needs to reach 165. You can’t just cook it at 140 for twice as long.

Mfr’s spec say 12 hrs at 80C (I did 12h at 70C) and 2 hrs annealing at 194F, which is what I did.

You got off easy this time.

If you trust your oven to anneal, trust it to dry. Dry your filament to manufacturer recommendation

Urutau AR-9 Barrel Retainer done in PolyMaker PA6-CF on a QIDI Q1 Pro.

Per PolyMaker’s reccomendations:

Dried for 12hrs at 70C in a Comgrow SHO2 drier, then printed directly from the dry box. Annealed for 2 hrs at 195F in my oven.

The Q1 Pro is on sale at Amazon for $399, reg price is $499.

Oh yeah.

Leaving aside the legal issues (you could get a stamp for a SBS after all), it would be dope. Tough to do with full power, but the short shotshells ought to be achievable. Wait, even full power 12 gauge isn’t that high of a pressure. I think this would totally be doable!

Maybe a Glock 17L as the pistol, to give you some rail room to work with. Seamless tubing for the barrel. Printed rail mount and pocket for FCG. Not sure what the internals would look like, but I’m thinking you could do a custom Glock frame that has a slot in the front of the trigger guard, and a trigger you would press forward to fire the shotty. That way both triggers are protected by the guard and ordinary fire discipline keeps you from AD. You just don’t have a lot of room for a hammer or striker, so it’s gonna take some thinking to work that out.

I’m very aware it’s airsoft, that’s precisely why I asked if anything like this exists and holy fuck I hope it does.

As far as I’m concerned there are a couple of pistols, specifically revolvers that had secondary barrel in the middle of the cylinder and could shoot in a scattergun pattern; first one that came up on google was the LeMat Revolver.

You are right, it would need to be steel levels of beefy to withstand a shotshell but nothing a SCS file and a trip to home depot couldn’t solve. I want that wrist breaking power but in a random striker-fired mag fed pistol that allows for under barrel accessory attachment.

Admit it, it’d be dope.

Looking at that “shell” that’s airsoft. Not saying you couldn’t do something like this but I don’t think it’ll look like that, probably something a lot more beefy lol

The tail of the piston is corroded, also the hole in the gas block where the tail of the piston goes in also had some of the corrosion, I had to file it a lil bit too to allow smooth action.😉

The gas rings should be the only thing touching the bore. There should be more than enough gas that it moving “smoothly” wouldn’t be an issue.

Like worrying about sand under your wheels when you’re about to get hit by a semi truck.

Look through the gas port drill hole in the gas block, you should see the gas port hole in the barrel

VMAC 100%. Just make sure to get a stronger firing pin. Mine is from AVES and I’ve had no issues with it. The velocity one won’t hold up to AR fire control groups. Will snap the tip. AMHIK…lol.

Good luck buddy, once you give something away it is out there forever. Your design will just be posted by someone else now, and you will just be forgotten.

The poor man’s temperature mod is to print slow as shit so that the nozzle and filament reach as hot as possible. This is neat though - guessing it works on the P1s also?

Thanks! Always glad to try anything that makes “sense”. Been printing (not guncad obviously lol) since the Ultimaker2 days so I’ve got at least some “feel” for it.

Can’t wait to try these PPA-CF parts, and I’m especially giddy to get my hands on PPS-CF… lower layer adhesion it seems but INSANE heat deflection along with tensile and other strengths, plus moisture insensitvity.

You technically can get away with printing PPA-CF, at least Siraya’s stuff (also called PAHT-CF by them) at 300*C (actual IRL nozzle temp) buuuut I can tell you the extra 20C or so make a BIG difference at least in appearance, feel, everything really. I may even try printing another part or two at even a few degrees higher to test.

I appreciate you testing your luck with ppa-cf. I know it seems like there’s a lack of real-world data for our application, so good work. Had no idea you needed that high of temperatures as well… Side note, those came out gloriously.

I assume pla+ could be used in place of cf? I live in a state that calls the ss a machinegun trigger. They also have cops who will shoot you 60 something times and say you died of natural causes. I’ll stick with semi auto until I move.
