Do you want the maximum possible range with your SSG?
Increase the fps/power of your rifle exactly to the legal limit of your field with the fps adjuster rings. You can put them on the spring guide to adjust the muzzle velocity of your SSG.

The rings are machined by CNC and the material used is hardened stainless steel.

Compatible with all SSG products.
Not compatible with M190 and M220. Those springs need too much space in the piston and don’t allow the rings to be there.
The rings can only increase power.

One set includes:

2mm long ring + 4mm long ring + 8mm long ring

Outer diameter: 13mm
Inner diameter: 9mm
