ACP Ariakon Sim-4 Velocity Booster Kit

Description

This is a velocity booster kit (VBK) for the Ariakon Sim-4 and other Ariakon markers using a 4MM spring guide pin (Ariakon part# 29). The kit consists of 3 different length spacers that slip onto the spring guide, singularly or in conjunction with one another, to increase drive spring tension. This kit does not require any special tools or extra parts for installation, gets rid of any guess-work…it’s simple bigger spacer = more velocity. Remember to re-chronograph the marker after making any changes to the velocity.
