Full description


Many variable STANAG magazines give you the option between 30 and 130 rounds. This variant from Arcturus switches between 30 and 135 rounds! Does that extra 5 BBs make a difference? We say yes! Loaded via the fill/feed port located on the top of the mag using a speed loader, the magazine capacity is adjusted by removing the baseplate on the bottom of the mag, removing the interior portion of the mag and sliding the red switch on the interior.

Featuring the classic sleek and smooth STANAG design that will fit right into any AR loadout, the mag is constructed from lightweight but high-density polymer for quick reloads.

This mag will not emits sounds of BBs jostling when you run as it is a spring-loaded midcap, so if you are a more discrete player who values the ability to sneak around this is the mag for you!
