There's a gorillion 3D printed AR spring jigs on the internet.

/3pn/ sends its regards

Is it possible to make a semiautomatic (non double action) firearm that doesn't need a spring?

>>64916582
>Do you think that will change?
Not because someone made a working .22 LR.

Much in the way that 4k video gaming was "supposed to be" cheap and widely adopted "by now", or batteries were "supposed to" have made some massive leap, or fusion power is "supposed to" be viable any day now, the advancements in 3d printing materials+precision+quality have not become reality after 15 years.

If you want to play with toys, run a failed etsy shop, make some youtube videos about flavor of the month science projects, whatev but I'm not dumping $3,000 and a lot of time into it to get caught up in then
>which of these 1,000 different filaments is actually any better than real ABS and glass-nylon

An a1 mini is like $220 dude what are you on about

>quality+precision

>>64917656
Let's try again: what are you not spending $3000 and a ton of time on, exactly? Vagueposting nigger

>>64917635
>fusion is "supposed to" be viable any day now
The Iter experiment has a very clear roadmap and schedule, nobody's claiming it's viable yet.

You need a spring even for double action unless you think you can pull a trigger fast enough to set off a primer.

>>64917656
What $3000 machine do you think is going to give more quality and precision than what you can get for $500 plus another $200 or so worth of upgrades? Also 4k gaming is cheap, how poor are you?

>>64917635
My Ender 3 S1 literally prints ABS and I got it at a firesale for like 250 bucks including the heated enclosure.

Shills always come out for 3dp threads
Makes ya think
150$ Ender and you can make AR lowers

>>64916946
you dont necessarily need a metal spring but you need a spring effect.
