The J-Plate Base Pad directly replaces the factory base pad on the Magpul GL9 PMAG (#558151 & 123705) for Glock. The J-Plate is machined 6061 hardcoat anodized aluminum, and features laser marked identification numbers. The base pad is easily installed, utilizing the factory retention plate, and features 10 laser marked identification dots. The base pad adds additional weight for faster magazine changes, but does not increase magazine capacity.
