The Magpul Tactile Lock-Plate is a magazine enhancement that provides the user with the ability to rapidly and easily identify/ differentiate magazines with mixed loadouts such as ball, tracer, supersonic and subsonic types via raised tactile features. These features are 1/8″ raised ridges that protrude through the magazine floor-plate opening and are purposely pronounced at an optimum height to ensure functionality with gloved hands. The Magpul Tactile Lock-Plate comes in two fully distinct configurations of 1/8″ raised ridges: Type 1 – single ridge and Type 2 – double ridge. These designs provide the user with the ability to quickly and confidently identify three separate loadouts by tactile feel when utilized in conjunction with standard floor plate/lock plate combinations. Full functionality remains with the magazine inserted in a weapon or in a magazine pouch while retaining the proven PMAG Gen M3 strength and performance characteristics for total end user confidence.
