When you want to upgrade your AR10 buffer why would you pick anything but the best? Primary Weapons Systems is at the forefront of the next evolution in small arms. They have developed the PWS Mod 2 Steel Body .308 buffer for the AR10 to improve the function and reliability of your AR10 using a standard carbine length buffer tube.

The PWS Mod 2 Steel Body Carbine Buffer for .308 uses the same advanced design and surface processing as the Mod 2 H2, H3, and H4 buffers, but in a buffer sized for the AR10 platform. In order to ensure proper cycle function in AR10 systems that use a standard carbine length buffer tube the .308 buffer is foreshortened. It weighs in at 4.4 ounces and is the standard buffer shipped in Primary Weapons Systems MK2 Lowers and complete rifles.

The PWS Steel Body Buffer line features a fluted contact surface that allows it to run cleaner, naturally shedding debris while it suffers far less from the effects of friction because it uses far less contact surface throughout the recoil cycle. The self-lubricating FNC LIFE HD treatment used on every PWS Mod 2 AR10 Buffer ensures a long service life with near-flawless operation. Because it’s a process that alters the upper layer of steel rather than a coating that lays on top, the FNC LIFE HD treatment won’t crack or peel like treatments that overlay existing metal. It’s less susceptible to erosion under normal use and the service life of FNC processed parts is significantly longer and requires less maintenance than those using traditional coatings.

When you’re ready to evolve Primary Weapons Systems is ready to lead the way. Don’t get left behind. Primary Weapons Systems, Because It’s Time.
