Three springs are included in the kit, and are colour-coded for easy identification:

Features:

• It ships assembled with Volquartsen's bright-finish, standard rate spring. This configuration is a direct replacement for the Ruger KA-57 recoil assembly.
• A gold, heavy weight spring, for high velocity ammo.
• A dark-coated, reduced-power spring. This spring can be used for a softer recoil with standard velocity ammo. It can also be used with most subsonic ammo, but does not enable the use of 22 short or CCI Quiet ammo.

The standard rate spring is suitable for subsonic, standard and high velocity however you will see your best results using specific spring weights.

Details:

• Recoil spring assembly is designed for a variety of pistols: the Volquartsen Scorpion, Ruger MKI, MKII, MKIII, MK IV, and the Ruger 22/45.
• Made in the USA
