This polymer SSR90 magazine has more transparency to get a better overview of how many BBs you have left and a better fitment with the SSR90 for smoother reloads.
The magazine is perfectly compatible with the Novritsch SSR90 Magazine Pouch. We recommend you grab one as well!
The 180 rounds magazine project was canceled since reliable feeding with 0.32g bbs at a high rate of fire could not be achieved.
