18" 6MM ARC AR-15 Upper Assembly | SHAW Barrel | 1x7.5 SS Rifle Length HBAR Barrel | Flash Hider | 15" MLOK Rail
Far from being just another addition to the lineup, the 6mm ARC is a sophisticated, purpose-built solution for the AR-15 platform that brings the long-range precision of a 6.5 Creedmoor to a compact gas gun. This system thrives with heavy, aerodynamic projectiles, specifically tuned for 103gr to 108gr Match loads to provide unrivaled ballistic coefficients and supersonic stability beyond 1,000 yards. If you're building a dedicated PRS-lite rifle or a high-performance deer and pronghorn rig, a 6mm ARC upper assembly offers the low-recoil accuracy and superior wind-bucking capabilities required to push the limits of the small-bore gas gun.

Complete upper
The beast. The upper end of the ar platform., 6mm arc can harvest deer comfortably to 700 yard. I can say this, I did a neck shot at 687 yards.

6mm arc 18 inch
Love the upper and it shoots perfect. Love the way it cycles with the SA gas block which is a must have.

18" upper Shaw
Great looking well packed upper arrived fast. I will say it loves hornady ammo and was easy sub moa at 100 yards. This is my second Shaw barrel for a reason.

18" 6 Arc
Mounted one of my Leupold 3x9x40's on this upper and it is dead nuts at 100 yards. Literally 1/2 groups that I can cover with a quater. I was using a lead sled to be fair.

Impressive
Finally jumped on the 6 ARC bandwagon with this one. Excellent groups out of the Shaw barrel on this upper. I'm impressed.
