If you are looking to build an AR-10 but want to push the limits of what the platform can do, the Criterion Barrels are the way to go. With a 416R stainless steel barrel chambered for 6.5 Creedmoor, you will be ringing steel at distances beyond the capabilities of .308 with relative ease. This 6.5 Creedmoor match grade barrel is compatible with DPMS, Remington, Bushmaster, Fulton Armory, and ADM pattern receivers, so you can build the precision gun you have always wanted. It features their popular hybrid contour which tapers toward the muzzle to reduce weight without negatively impacting accuracy. The 416R stainless steel bore is highly machinable resulting a high smooth finish designed for consistent accuracy. This 18” 6.5 Creedmoor barrel is perfect for your next precision build.

  • 18” barrel with 6.5 Creedmoor chamber
  • 416R stainless steel
  • Nitride finished barrel extension
  • Hybrid barrel contour
  • 1:8 button rifled twist
  • Rifle length gas system with .750” diameter

The rifle length gas system on this barrel has a .750” gas block diameter and features a dimple beneath the gas port for installing a set screw style gas block. This simple addition helps to lock the gas block down and ensures it won’t move while shooting. Criterion designs their gas system lengths to accommodate DPMS standard AR-15 gas tubes. This Criterion Hybrid barrel is built to withstand years of heavy use while providing exceptional accuracy.

Criterion Barrels are known for building high quality, precision AR-15 and AR-10 barrels as well as barrels for older firearms like the M1 Garand, M14, and Lee Enfield. Their barrels are used by the US Army Marksmanship Unit Action Shooting Team and the US Marine Corps Combat Shooting Team and are proven to win matches time and time again.
