Increase the fps/power of your SSR4/SSR74 exactly to the legal limit of your field with these fps adjuster rings.

You can put them on the spring guide to adjust the muzzle velocity of your AEG. The package comes with 2 rings. 1 FPS adjuster ring will increase the  power by 0.15J, on average, and you can stack a maximum of 2 rings.

Do not use any adjuster rings if the power is already at or above 1.5J.
