I’ve got a roll of 3D Fuel’s PCTG Pro I’m trying out on some NylAUG mags. Next contender will definitely be PET-CF.

FOSSCAD @lemmy.ml PetgCF for Accessories?
What’s the consensus on petg cf for accessories like pistol grips and v/afgs? I’ve gotten through a few rifle builds with petg cf pistol grips, and I’m pleasantly surprised how they’re holding up. (DB tail gunner grip, ciwielab m7 DeAR lower, eryone petgcf)
FOSSCAD @lemmy.ml DB Sig Pro/SP2022 Update
Added a small shelf inside the frame to keep contact with the axial locking spring. The original frame had a sizable gap between the locking block and frame, causing the locking spring to pop out of place during field stripping. All credit to herzandherz and dbfirearms for this awesome frame.

TheShittinator explained it perfectly. I should have been a little clearer, my brain is an alphabet soup of abbreviations at this point.
I’ve had a printed ADAR stock (think a California compliant thumb hole stock that connects to the pistol grip, but made in Russia) on an ar15 lower I’ve been beating the piss out of. Mortaring, throwing it about, and just out right abusing the gun and it hasn’t shown any signs of breaking down or shedding material.
The only failures I’ve had so far are with magazines - either mag bases blowing out or feed lips shearing off if they get dropped, loaded or unloaded.
