The SOLGW XP Intermediate/Rifle length spring is wound from 17-7 stainless steel, which is then passivated for maximum corrosion resistance.  This spring offers roughly 10% additional power over the standard mil-spec rifle spring, and pairs well with SOLGW rifles (having been built to use extra power springs for years) as well as most other suppressed firearms.

As this is a rifle length spring, it is only for use in Intermediate/A5 length, and rifle length, buffer systems.

Color coded BLACK for easy identification versus a standard rifle length spring.
