Using this on BCA 10.5 AR22LR and 10.5 AR22WMR. I printed in PLA, if printed again I might print in other filament but in 5-6 months of moderate use no issues with the PLA.

Designed to fit Mil-Spec sized buffer tubes, Carbine or A5 length.
Carbine buffer tube LOP fully extended = 12.75in.
A5 buffer tube LOP fully extended = 13.5in.

There is tolerance designed in and for a reasonably well calibrated printer there should be no need to scale the parts.
If the Threaded_Pin needs to be scaled, it should be scaled on X/Y only and in equal amounts to keep the threads matched with Brace.

My print specs:
FLSun Super Racer
PLA
0.4 nozzle
0.12mm layer height
5 x walls, top and bottom
30% infill
