The Superlative Arms Adjustable SS Piston Kit is a great option for anyone that wants to reduce the amount of carbon build up and heat that is entering into the system of their AR-15 style firearm. With 30 locked gas positions to choose from, almost any ammunition from very soft shooting reloads, to factory manufactured ammo will run flawlessly. All gas that is not needed to cycle your gun is bled through the front of the piston block to keep extra debris away from parts that are critical for the cycle of operations. The melonite treated piston block is very easy to maintain because this treatment makes the steel surface much slicker, harder and lowers the coefficient of drag which helps for the piston to reliably cycle.
