This upgrade spring is not needed in most builds, but for Momentum and other blasters that can take advantage of it, the solenoid can reach up to 40 rounds per second in full-auto.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003e• Neutron RoF Upgrade Return Spring\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e• Higher-strength spring for faster reset\u003cbr\u003e• Up to 40 RPS full-auto!\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e• Designed by Eli Wu for Momentum\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e• Compatible with Neutron Solenoid\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eINCLUDES:\u003c\/strong\u003e\u003cbr\u003e• 1 High RoF Return Spring\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003ePERFORMANCE:\u003c\/strong\u003e\u003cbr\u003eAverage Rate of Fire\u003cbr\u003e• Up to 20 RPS (electromechanical)\u003cbr\u003e\u003c\/span\u003e• Up to 40 RPS (32V boost circuit*)\u003c\/p\u003e\n\u003cp\u003e*\u003cem\u003e40 RPS requires extra circuitry.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eEli has used a DC-DC boost converter designed for 25A burst and ~10A averaged.
