Extra power spring - Griffin Armament Extra Power Buffer Spring

Steve's Review of Griffin Armament Extra Power Buffer Spring
I don't have a sprinco blue to compare to but I would say its Griffin's equivalent. Quality is great. Took my over gased aero 16" midlength from a 1:30 ejection pattern to a 3:00-3:30 when I paired it with the sob buffer. So far so good, can't speak for longevity but Griffin makes good stuff
