The regulator takes tank pressure and hands the engine a steady working pressure, and if that drifts, every shot drifts with it — however good the engine.\u003c\/p\u003e\u003cp\u003eThe Micro is PolarStar’s compact answer. Second generation refines a design built for setups where size and weight matter: a tank-as-stock configuration, a speedsoft build, or anywhere the bulk of a full-size regulator is a nuisance.\u003c\/p\u003e\u003cp\u003eIt sits below the \u003ca href=\"\/products\/polarstar-modular-regulator-system-mrs-regulator-only\" style=\"color:#1B3A6B;\"\u003eMRS\u003c\/a\u003e in both size and price, which makes it the sensible starting regulator for a first HPA build.
