Can you spot the real one? Featuring ARK evo

I have a 1" split at a layer line on the lower, right above the safety selector. I was going to reprint but unfortunately I lost my remixed step files somewhere in the past 3 years and 2 new computers.

I've already put a handful of rounds through it without issues even with the crack. Just how stupid would it be to glue it and keep on keeping on? I'd rather not re-remix the step files for a new lower. Strictly a range toy that probably gets shot once a year.

Superglue fumigation on PLA+ prints

I'm curious if anyone has tested if superglue fuming improves strength of PLA+ prints. Theoretically, it would seal the print in a super thin layer of superglue. I would be curious if it would stick to the print, and if it would cause any deformation due to the exothermic properties of superglue. Any opinions welcome. I might test this if there is enough interest. A note: please dont attempt this without real ventilation and proper PPE, superglue fumes are extremely nasty and won't leave your lungs if inhaled.

PPPX Light Primer Strikes

I recently put together a PPPX using a Creed parts kit. I am getting light primer strikes and can’t figure out why. I have made sure the hammer is completely clear of the frame and not rubbing at all. Has anyone else run into this issue and figured out a solution?

Super Safety locking up

Deez Nuts Tactical Super Safety. Grinded down the trigger and the measurements fit in the cam groove. When on SS the trigger won't pull and when I fire and pull the trigger back, then set to SS and move the lever manually the trigger never resets.

Australia

Anyone familiar with obtaining slides and barrels in Aus I find on here it’s mainly American based I miss shitonwheels and the other European hobbyists who help people like me I guess we still have just-in-case working hard like usual needs to be more builds like the fgc9 and the soon to be “not-a-glock”

Sick of being limited to the harlot and the songbird

My beach pigeon and elratto are on pause due to parts 😢

3D Printed mags; where do i find them?(can you even find them?)

I've been slowly starting to source parts to fix my old Walther P99, and i've slowly delved into the 3d printing firearm world as i recently bought an Ender 3.

The top retainer on the original magazine bent after dropping it, and cracked upon bending it back.
I'm looking for a magazine that will work *long enough* so that i can test the firearm until i can source a genuine Walther mag set.
I searched far and wide but cannot find any magazines, for any firearm. Is this a legal issue? I already printed a couple bits and pieces that were easily sourced on websites like Cults. They turned out great. What's the deal with mags? Am i not looking in the right places? I've looked around on the Wiki and still can't find much other than lower's for p99's.

m16a1 stock - reference model

Is there any good reference models for an m16a1 stock? looking to make a removable m16a1 stock for a carbine buffer tube. So i can switch out between a car15 stock and a m16a1 style stock without removing and replacing the buffer tube each time.
