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.
