Velocity Spring 5-pack

Need more velocity? These stainless steel drive springs are the answer if you have early versions of the Custom Carbine or an SA200 that just needs some help getting into the 300-350 feet-per-second manufacturer recommended velocity range. These stainless springs are stiffer, allowing the rear bolt to open the air valve for a slightly longer period, thus increasing velocity.

I tested these springs on 6 different launchers and found velocity improvement from 15 to 55 fps! This is a simple fix for a launcher that needs more velocity.

Launcher maintenance and upgrades should only be performed by certified armorers.
