KAK Industries AR-15 9MM Carbine Buffer
This 9mm buffer is designed to be used on a new or converted AR-15 shooting 9mm. It is also used to reduce cycle rate of the AR-15 and felt recoil.
Real tungsten 5.4 ounce filled buffer to guarantee correct timing and firing of 9 mm and 9 mm +P loaded ammunition.
It is important that all 9 mm buffers have enough weight to ensure that the bolt stays closed long enough for the entire powder charge to burn 100% along with adequate closing of the bolt once the round is fired. This ensures safe firing of the 9mm AR-15 Rifle or Pistol. 5.2-5.4 Oz is the correct weight.
All 9mm Ar-15's need this weight of buffer so there is no firing out of battery. Firing out of battery is where the rifle cartridge is not fully seated in the chamber and the firing pin is struck blowing the side of the case out and usually your upper receiver turning your gun into a bomb.
5.2-5.4 Oz Or greater buffers slow the cyclic rate of full automatic M-16 rifles/M4
This Buffer is made In the USA and they are each quality inspected.
