Hardened Arms LLC is pleased to announce the arrival of the Ultimate 6.8 SPC II upper for the AR-15 platform!  Custom machined in-house using the very best US steel, we use 4150 CMV  to create a stress relieved, air gauged and hand polished precision barrel for your upper. The barrel is coated with Melonite which is 3 times stronger than chrome and extends the life of your upper and increases accuracy due to its ability to penetrate and strengthen the steel without affecting the bullets path.  We run a 1:10 twist to stabilize the heavier 6.8 SPCll ammunition which affords a higher accuracy return. The 6.8SPCII caliber is a great round for longer range hunting on the AR15 platform. Often referred to as the 300 Blackout's big brother, it reaches out with real stopping power for those 300 to 500 hundred yard shots.
