The KT68 6.8mm Upper
The KT68 was designed from the ground up to provide rock-solid reliability under every circumstance. We took every aspect of the way an upper works into consideration, and examined all in the light of this exciting new cartridge.
Our goal is to provide an AR-15 upper which transforms your AR-15 into a truly ALL PURPOSE RIFLE.
The KT68 comes with a 30-day money-back guarantee and a one-year warranty. Every KT68 is function tested with very high pressure loads before being shipped to you.
