Eemann Tech Recoil Spring for CZ Shadow 2 Cadet adapter - weak (blue) for low velocity ammunition.
The blue spring is designed for use with subsonic ammunition, and the red spring is designed for use with high velocity cartridges.
While upgrading to a weaker or stronger spring is not always necessary for most types of ammunition, upgrading still has its advantages.
A spring that is matched to your type of ammunition, or at least one that is more suitable, can noticeably improve the weapon's firing behavior.
If the breech cycle is a bit smoother, the weapon may seem more pleasant to handle.
Made of heat-treated steel for best performance and quality!
Similar to OEM Blue spring for low velocity ammunition.
Important ! Any kind of replacement of parts, modifications, changes, etc.... in your weapon outsource to a specialized gunsmithing company.
