Recommended Ammunition:

  • Use only commercial grade ammunition in its original packaging that corresponds with the caliber of the gun.  The correct caliber is imprinted on the gun.
  • 5.56mm or .223 Remington Brass Cased with a minimum of 55 grain.
  • Never use reloaded, “refurbished”, hand-loaded or non standard ammunition of a different caliber.
  • Never use dirty, wet, corroded, bent, damaged or oiled ammunition.
  • Unfortunately, it is not possible to adjust a semi-automatic gun to all loads.

*Highly advise against using Steel cased ammo due to excessive wear and tear from steel and lacquered coated rounds can cause premature carbon buildup and stoppages.
