Energy stored in the spring can be transferred to the BB more efficiently because less energy is required to accelerate the piston. Using a lighter spring can make the cocking action faster and reduce the load generated by the piston's impact. However, a piston that is too light may increase muzzle-velocity variation if the system is not balanced.\u003c\/p\u003e\n\u003cp\u003eThe adjustable piston can be used to find a compromise between consistent performance, a light spring, a fast cocking cycle and long service life.\u003c\/p\u003e\n\u003ch3\u003eSetup tip\u003c\/h3\u003e\n\u003cp\u003eChronograph the rifle in sets of 10-20 shots using different mass settings and BB weights, such as 0.40 g, 0.43 g and 0.45 g.
