A stock spring often lacks the strength to pull the nozzle back against this friction, causing it to stick forward in the hop-up chamber. The 300% spring forces an instantaneous, crisp retraction.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eStabilizes FPS Consistency:\u003c\/b\u003e If the nozzle does not pull back cleanly and predictably during the blowback phase, the internal gas valve cuts off erratically. By ensuring uniform, high-speed nozzle reset every single shot, this spring stabilizes your muzzle velocity (FPS) spreads during rapid, sustained semi-auto or full-auto strings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eEssential for Heavy Steel Bolts:\u003c\/b\u003e If you have upgraded your MWS with an aftermarket steel bolt carrier or a high-speed short-stroke buffer system, the entire cyclic window shrinks.
