Rugged and well-designed, the Mission First Tactical Standard Capacity Polymer Magazine for 5.56x45 mm NATO cartridges (SCPM556) holds 30 rounds, and represents a cost-effective refinement of the ubiquitous aluminum magazines. Polymer construction allows features like grip-enhancing front ribs and side panel stippling. As well, the polymer floorplate has evolved to include a paint marker identification grid, dual drain holes and a two-button, tool-less disassembly system for added security and easy maintenance.
