The Magpul Tactile Lock-Plate is a magazine enhancement designed to provide you with an ability to rapidly identify or differentiate magazines. The lock plate is a great enhancement which can allow you to separate magazines that might be loaded with ball, tracer, supersonic or even subsonic loads. The 1/8" raised ridge protrudes through the magazine floor plate opening to allow for this quick identification. The lock plate is a drop in replacement part that installs easily. The type 1 style features a single ridge, and the type 2 style features a double ridge. Check below to see if what you are ordering matches the specifications you would like.
