Super 42 rifle nit
Reviewed on March 26, 2026Verified with Build

super 42 rifle length spring is geissele top tier, braided wire keeps it quiet through the cycle. one nit, the finish on mine has a slight blue tint vs the black i was expecting, only visible against another super 42 in direct light. functions correctly
