This JDG SUS Stainless Steel Loading Nozzle Spring for Marui Hi-Capa / 1911 GBB – 280% is an ultra-high-tension internal upgrade designed for extreme cycling speed and heavy custom slide builds. Constructed from high-tensile SUS stainless steel, the aggressive 280% spring rate ensures near-instantaneous nozzle retraction and positive BB loading, eliminating nozzle drag even when using heavy green gas, high-pressure red gas, or heavy steel/aluminum slides. It is specifically recommended for high-rate-of-fire race guns or heavy-recoil setups where rapid nozzle resetting is essential to prevent feeding jams
