This JB3D printed biathlon lever is designed to fit the Air Arms HFT500 / S500 / S510 / EV2.
Due to variations in the levers we have now added a grub screw to ensure a solid grip on the lever.
The screw will make a small mark in the back of your rifles lever, please see listing picture for example
Please choose the colour of the lever of your rifle when ordering (you are not choosing the colour you want our lever to be, they are only available in black)
There are 2 variants of the lever:
Single Sided
Double Sided
Choice between the two is down to your personal preference on looks and feel as they both do the same job.
