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.

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.
