The Quad Coupler is an attachment for Magpul's PMAG Gen 3 that allows the user to attach four 10rnd magazines together vertically end-to-end and horizontally side-by-side to increase reload speed and allow for more ammunition to be carried with the rifle.
The magazines are spaced in order to clear the magazine well of the SCSA Taipan and all standard milspec AR15 derivatives.
The coupler replaces the standard baseplate of the magazine and snaps in place.
The coupler can be removed using a small screwdriver to depress the spring tab through the hole in the back.
