Air Arms S510 Picatinny Rail Adaptor for tank and barrel

This adaptor slips on to the barrel and tank of your air arms s510 allowing a bipod to be placed at the farthest point forward. Also so you can attach anything easily to the bottom of the air rifle. Add a piece or two of electrical tape to the inside of the large diameter tank part to make the adapter tighter (if needed…). Designed to fit #8 screws imperial or 4mm. I printed it with ABS no infill.

No need to disassemble anything to install. Just slip over the top of the small barrel and press down hard. It will slip on. Then add the picatinny rail part and put the screws through the holes.
