Every one of my carbines has an H buffer (or heavier in some cases). Simply put, adding some weight to the cycling mass in your AR-15 can smooth the recoil pulse and increase the reliability of your carbine.
The Weapon Outfitters Heavy Buffer is one of the many H buffer options that are available. It is unique because it is filled with powdered tungsten instead of steel and tungsten weights as you would find in a typical H buffer. Some claim that the use of powdered tungsten further smooths the recoil pulse. Oh, and if you didn’t notice… it is bright red!
