Full description


This magazine is high capacity, holding a total of 300 rounds, which is the standard for most M4 high caps. It is made to fit and work with most M4/M15/M16 platforms, as the design is a universal standard. It is filled by opening the fill window at the top of the magazine and pouring your BBs in. The magazine feeds rounds by winding the clockwork wheel at the bottom enough so that it continues to unwind and feed BBs as your fire. If you need to carry more BBs in the field before having to go back to the safe zone to reload, pick up some spare mags today.
