Our JB3D-printed bag riders are precision-designed to fit the Air Arms HFT500.
When shooting from a bench, maintaining rifle stability is essential. However, many stocks lack a solid, flat base for proper rear bag support. In some cases, angled or concave stock designs can even conflict with benchrest rules, making rifles difficult—or even unusable—in competition.
That’s where our bag riders come in—providing a stable, compliant shooting platform while seamlessly integrating with your rifle.

Choosing the Correct Bolt Size
The easiest way to determine the mounting bolt size you need is to check if your stock has exposed barrel nuts on the side.
-
If your stock has exposed barrel nuts, choose the 5mm bolt option
-
If your stock does not have barrel nuts, choose the 4mm bolt option
Alternatively, you can remove the existing bolts and measure the thread diameter to confirm the correct size.
We have also included a guide in the listing photos to help you quickly identify which bolt option you need.
Custom Options Available
We also offer custom sizes and bespoke designs on request, allowing you to tailor the bag rider to your exact setup or competition requirements. Please contact us with your requirements.
