6.5 Creedmoor AR Barrels

Converting your large frame AR to shoot 6.5 Creedmoor is a simple barrel change. Whether replacing a .308 barrel or building a 6.5 Creedmoor AR from parts it is advisable to use a new bolt and of course verify proper headspace. Never use a bolt on different barrels. Many barrel manufacturers can provide a matching bolt.

It’s important to note that 6.5 Creedmoor is a relative new comer on the AR scene. A good knowledge of firearm function is imperative. Some builds and upgrades might require tweaking of the gun to function consistently and accurately. We recommend using and adjustable gas block when possible.
