Steel and aluminum don’t mix, especially concerning the upkeep and maintenance of your AR-15, so Cross Armory developed the state-of-the-art PIN PAL to reduce rotational wear.
The AR-15 was not intended or constructed for frequent opening by its operator. The increased use adds wear and tear on the upper receiver’s takedown pin hole as a steel pin bearing on the aluminum receiver.
As such the PIN PAL puts an end to receiver’s being chewed up from grating between steel and aluminum parts.
The PIN PAL puts a steel pin bearing on a pre-lubricated MIL-SPEC metal bearing to keep the gun tight and functioning as it did when it was born from the factory.
Installation of the PIN PAL takes minutes beginning by separating the upper and lower receivers. Remove the rear takedown pin and then front takedown pin to provide separation between the two receivers.
Remove the nut from the PIN PAL and then use the PIN PAL front takedown pin to seed the captive bearing into the upper receiver. Use a nylon mallet (or something similar) to tap the pin, thus pushing the captive bearing into the receiver. Do not use a metal hammer as it could damage the PIN PAL.
When the two receivers fitting properly, insert the PIN PAL with the logo on the outside of the right side of the firearm. Make sure the PIN PAL is flush with the lower receiver and then tighten the nut to make sure it is tied to the lower receiver.
