Summary

Updated May 6, 2024: Further simplified print. Now uses the Floating Holes Trick to eliminate the printed “washer cover” part.

Share your passion for shooting sports, without attracting unwanted attention from haters. Those who know what it is, know what it is. To everyone else, it's just some kind of gear or something.

My original “over-engineered” AR-15 “bolt head” trailer-hitch cover had some issues, up to and including falling off on the road. This new version is somewhat simpler and, I hope, stronger.

Features:

  • Dimensionally-accurate (but scaled up) AR-15 bolt head.
  • Installs using standard hitch-receiver pin.
  • Two-part print.
  • Reinforced with embedded steel threaded rod.

Additional tools/materials required:

  • 105mm length of #8-32 threaded rod.
  • Two #8-32 “nylock” nuts.
  • Two 1/8"x3/4" flat washers.
  • Good epoxy (JB-Weld, etc.)
