Product DescriptionThe Magpul Tactile Lock-Plate Type 2 is a simple, rugged magazine enhancement designed to help you quickly identify and differentiate magazines with mixed ammunition loadouts by touch. Built from durable polymer with a black finish, this Type 2 lock-plate features two pronounced 1/8-inch raised ridges that protrude through the magazine floor-plate opening, making identification fast and reliableeven with gloved hands or in low-light conditions.
