SSG FPS Adjuster Rings

Obtain the maximum possible range with your SSG.
These rings 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.

One set includes:

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

  Outer diameter: 13mm Inner diameter: 9mm

 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.
