Inception Designs Autococker Master Spring Set

Main Spring Set, Trigger Return Spring Set, Sear Spring Set, and Valve Spring Set

The Spring force can be easily seen from the number of coils on the spring. Fewer coils are stronger, more coils are weaker.

We recommend using Main Spring B or C initially (B will give higher velocity)

We recommend using Trigger return spring B initially (C requires a very well-tuned gun and frame, or will not work)

We recommend the sear spring C (Light Medium), but if the hammer skips, you may need a stronger spring (common for older guns with heavier hammer springs).

We recommend Valve Spring C initially.
