Installation notes MAG|Couplers use opposing teeth to grip the magazine body. They are designed for a tight fit and may require force to install. Applying a small amount of liquid dish soap or hand soap to the coupler teeth before installation will ease fitment. The tight fit helps ensure secure retention under recoil.
