Replacement of an upper receiver is an expensive proposition.
Fitment of the upper and lower receivers will become sloppy, making your weapon less dependable. This action will cause accelerated wear on the through-hole in the receiver causing the hole to expand and elongate. The gun manufacturer never intended that the aluminum receivers should be frequently pivoted on a steel front takedown pin. 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. 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. Increased use translates into increased wear on the upper receiver’s takedown pin hole. The AR-15 was not intended to be opened by the user with great frequency. Our MIL-SPEC Captive Bearing is made from oil-infused, porous metal for reduced friction 4140 ordnance steel – our front takedown pin is machined from 4140 steel with a melonite hard-coating for durability.Won’t permanently alter your weapon – If you decide to go with a different setup on your weapon, PIN PAL is easily removed and returned to the manufacturer’s factory set-up.The Captive Bearing can be press fit into any upper receiver without special tools Fits any standard ar-15 configuration – easily installs on virtually all AR-15/M4 weapons.PIN PAL bears on a lubricant infused bearing Lubricated captive bearing reduces wear – standard steel front takedown pins bear directly on the holes in the aluminum receivers.A more durable pin system is needed to prevent undue wear on the forward pivot point – the upper receiver’s take down pin hole Front takedown pin replacement – in heavily regulated states AR-15 owners are now opening their receivers with great frequency.
