The B52 Armory midcaps are a good option for those looking to step up to or expand their collection of midcap magazines. Midcaps do not rattle like highcaps and can feed better when taken care of. Midcaps can be loaded by hand, but Building 52 recommends using a speed loader which makes the job much faster.
Magazine Capacity: 140 Rounds
Made for M4/M16 style airsoft AEGs
