    PIN PAL by Cross Armory

    Original price was: $25.00.Current price is: $23.75.

    • Front takedown pin replacement - in heavily regulated states AR-15 owners are now opening their receivers with great frequency.  A more durable pin system is needed to prevent undue wear on the forward pivot point - the upper receiver's take down pin hole
    • Lubricated captive bearing reduces wear - standard steel front takedown pins bear directly on the holes in the aluminum receivers. PIN PAL bears on a lubricant infused bearing
    • Fits any standard ar-15 configuration - easily installs on virtually all AR-15/M4 weapons. The Captive Bearing can be press fit into any upper receiver without special tools
    • 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
    • 4140 ordnance steel - our front takedown pin is machined from 4140 steel with a melonite hard-coating for durability. Our MIL-SPEC Captive Bearing is made from oil-infused, porous metal for reduced friction
    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 Big Bolt Catch or BBC is an extended, ambidextrous bolt catch, designed specifically for ARs built with the Cross Armory Safe Mag 2 and Safe Mag .308*. Gun laws suck. But at Cross Armory, our aim is to design products that make the laws more bearable. Safe Mag 2 allows the user to drop a magazine automatically after opening the action, without the press of a button. The only previous downside to Safe Mag 2 was that, due to unique features of a non-MIL-SPEC AR, the user would no longer be able to use an extended bolt catch or battery assist device (B.A.D.) lever. That has now changed. Thanks to your requests, the BBC was born! The BBC functions just as other extended bolt catches but does not interfere with the function of the Safe Mag 2 or Safe Mag .308. The BBC is also compatible with with large frame ARs, like .308s, as well as billet and polymer lower receivers, unlike many other battery assist devices on the market. Made out of 4140 Ordnance Steel with a Type III hard coat, the BBC is a strongest, easiest way to ambidextrously catch and release your bolt with Safe Mag 2. The BBC can be operated with your trigger finger alone or in a traditional manner with your off hand, and can be used by both right and left handed shooters. Eliminate awkward and time consuming hand change overs during reloading and double feed fixes with the BBC for your Safe Mag 2.

*Works for most, but not all .308s. Please email [email protected] with questions.
