The RTR Series 18" 6.5 Grendel barrel is built for shooters who demand real-world precision without the wait. Made from our in-house Craddock Precision stainless steel blanks, this barrel is hand-lapped, stress-relieved, and ready to rock.
Designed around a rifle-length gas system, it ships with a matching gas tube and features enhanced feed ramps for reliable feeding under any condition. The 1:8 twist rate stabilizes a wide range of bullet weights, and the 5/8x24 muzzle threads with an 11° target crown ensure precision downrange.
This RTR barrel weighs in at 40.7 oz and accepts a .750” gas block. Choose from Straight, Spiral, or Diamond fluting and multiple finish options to match your build’s form and function.
