Ruger Mark III Bolt Racker
thingiverse
I've been looking for a practical racker for my Mark III beyond the standard "cone" design, so I decided to take on learning Fusion 360 and print out a custom "Halo"-style one today. I used ABS plastic for the print, and initial testing is showing positive results. A 8x32 machine screw fits snugly into the Halo's design.
