Very few AR15 users give much thought to the cam pin in spite of its pivotal role in the weapon's function. The performance of the weapon can often be improved by upgrading it with the American Build Arms (AB Arms) Nickel Boron Cam Pin.

The AB Arms Nickel Boron Cam Pin is machined and heat treated in accordance with Mil-Spec procedures, this cam pin is one of the finest on the market. The nickel boron coating sets it apart from the competition. This compound features a natural lubricity, so your weapon will function better even when the amount of lubricant on the bolt is diminished. It is also incredibly resistant to corrosion and general wear.

If you want to build a tough and functional AR15, get yourself the very best down to the smallest parts, and start with the AB Arms Nickel Boron Cam Pin!

    Well I actually have 3 nickel boron BCG's so I know how they preform especially if you start running a dry my friend who has a black phosphorus flat black BCG.She has a tendency to run dry.that part takes a pounding.its like forging a crease mark in that piece of metal,Wich will in time Crack in that spot. I replaced her came pin with the AB Arms Pro can pin and so far it's working if I can just get her to start lubing properly or I'm going to end up getting her a new Nickel boron BCG.

  • Excellent

    Not only did I get it fast, but I could actually tell a difference immediately after I switched out my mil-spec cam pin for this nickel coated one. Would highly recommend it as an inexpensive way to upgrade your BCG
