Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
3D Printed .22lr
3D printed goodness.
Printed upper, lower, barrel nut, grip and handguard.
Its only a .22lr based on the CMMG bolt & barrel. 9" barrel.
Pretty light weight, just need to go test it. See how many shots before it melts, if it melts.
The color was just because, its a toy, not meant for to be used for anything other than fun.
Well I just got a new printer for Christmas..... guessing the files aren’t on thingiverese though.
What machine do you have?
Infill etc

My feedback add 11-12 ish before the great servpocaylpse of 2012
I'll take it!
Its on an Ender 3v2.
0.20 mm layer height.
205C print temp. (Go 5C above max temp listed on box)
60C bed temp.
50 mm/sec print speed
edit to add 999 walls (replaces infill)
80% fan
sliced in cura 4.8 with tree supports.
GST3D Filament https://gst3d.com/ Good stuff. wait for sales, it $10/roll now. Inland PLA+ (eSUN) from microcenter is another one that works. Silk PLA has week layer bonding.
Lower is here: https://ctrlpew.com/ds1913-22lr-ar15-lower/ among other files
I modified an upper after if split. get it here https://www.thingiverse.com/thing:4696937, not sure if you can edit the print on the side here https://www.tinkercad.com/things/9hpEnVPcTre
Handguard from here https://www.thingiverse.com/thing:3141064
I had to modify the barrel nut from the above handguard to fit more snug on the upper. https://www.thingiverse.com/thing:4698216
On the charging handle, I filed off the guides since i filled in the channel on the upper. That was a major week spot. Not an issue since the CMMG bolt doesn't move.

What's the weight?
Awesome thanks. I got the ender 5 pro. Having first layer issues that I’m working through I sprung for simplify 3D as well. The support algorithm vs cura is night and day at least 2 years ago when i was running a robo3d printer

Not sure, but is lighter than the S&W 15/22. I guess I'll just have to take it to work and weigh it. I'm sure Polis will love a ghost gun in a state building... At least its a pistol so I can legally bring it into the building concealed.Originally Posted by Irving
How is rear pin retention accomplished?
9mm - because they don't make a 9.1mm
Looks like a hex bolt and nut.
That's so curious. The front has detent and spring provisions, but not the rear. Would be easy enough to extend a hole and cap with a setscrew, I suppose.
