The AR-15 was not intended to be opened by the user with great frequency. Increased use translates into increased wear on the upper receiver’s takedown pin hole. Cross Armory’s PIN PAL transfers the rotational wear from a steel pin bearing on the aluminum receiver to a steel pin bearing on a pre-lubricated MIL-SPEC metal bearing, keeping your gun as tight as it was from the factory.
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 an increase iron content porous metal that is stronger and more resistant to shock loads than standard oil-embedded bearings. Start-up friction (e.g. separating the receivers) causes the captive bearing to release a thin layer of oil on the bearing’s surface.
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.

The 2A Armament Full Mass Carrier (FMC) was designed as a high-quality, full mass bolt carrier group, with an emphasis on enhanced weight distribution. By relocating the bulk of carrier mass to the tail, the FMC keeps the firearm in a more balanced state. Weight that would normally be over the magazine well is now over the pistol grip on an AR-15 rifle when at rest. The distribution of weight is further utilized during the firing cycle as the FMC reciprocates along the plane located within the pocket of the shooters shoulder and primary support hand, instead of out in front between the magazine well, and primary support hand. The FMC can give the shooter an extremely reliable full mass bolt carrier group, with a weight distribution advantage over standard carriers on the market.
NOTE: Does not support the use of forward assist. Not compatible with full auto systems
