The Cross Armory PIN PAL is designed to reduce or eliminate that wear that will be caused by the repeated opening and closing of the upper and lower receivers, as now required by so-called assault weapon laws in states like California, New York, New Jersey and other states. The gun manufacturer never intended that the aluminum receivers should be frequently pivoted on a steel front takedown pin. This action will cause accelerated wear on the through-hole in the receiver causing the hole to expand and elongate. Fitment of the upper and lower receivers will become sloppy, making your weapon less dependable. Replacement of an upper receiver is an expensive proposition.
PIN PAL includes a pin, a locking nut and a MIL-SPEC captive bearing. The pin and nut are machined from 4140 Ordnance Steel for extreme durability. The custom machining of the assembly allows PIN PAL to be built to very tight tolerances.
The MIL-SPEC captive bearing is made from a high density polymer designed to hold tolerance and absorb and rebound in the harshest of conditions.
PIN PAL is a simple and inexpensive solution to eliminate the wear of a standard steel takedown pin on the softer aluminum upper receiver. It’s bad enough that legal gun owners have to separate their receivers in order to reload. It will be far worse if an upper receiver has to be replaced as a result.
Install Tips –
Do not force it in!
The bearing should press in, but not with excessive force, you should be able to gently tap the bearing/busing in with a rubber hammer. iF it does not go in easily, sand down the outside with some sandpaper and try again until you get a smooth press fit installation.
The pin should be pre-installed, and slip fit on the bearing.
