Included spring sets

Starting recommendations

• Main spring: B or C initially; Inception notes that B gives higher velocity.
• Trigger return spring: B initially. C requires a very well-tuned marker and frame.
• Sear spring: C (Light Medium). A stronger spring may be needed if the hammer skips, particularly on older setups with heavier hammer springs.
• Valve spring: C initially.
