Description
Discovery Medium Spring Gen2, This short heavy spring helps to increase shot count as well
as offer a greater tuning range with the addition of a power adjuster and is an excellent upgrade for your disco or maximus.
This spring spring combined with our power adjuster gives a power range of of 3-19fpe in .177 using a stock maximus.
It can be set for a variety of power and shot count combinations but were is does best is in the 8-14fpe range in .177 (expect slightly higher power levels and shot count in .22)
And at 13fpe using 7.9gr pellets you can get 45 shots from just a 1650psi fill and with a extreme spread of 55fps
Here is a sample shot string from a stock maximus with the Gen2 spring and power adjust installed its shot from a 200psi fill using 7.9gr pellets:
It is split into two parts because I’ve found the chronograph will some times loose connection after ~40 shots so as a precaution I split into two.
