Recoil Technologies AR-15 9mm 5.5oz Carbine Buffer

This 9mm buffer is designed to be used on new or converted AR-15 shooting 9mm. Depending on a number of factors including barrel length, a heavier buffer may work much better than the standard 3 oz buffer. It is also used to reduce cycle rate of the AR-15 and felt recoil.  This is a 5.5 ounce filled buffer to facilitate correct timing, cycling and firing of 9 mm and 9 mm +P loaded ammunition.
