AI AT barrel; Krieger; 6.5 Creedmoor; 24″
This is a chambered, ready to install replacement barrel for the Accuracy International AT (and similar) rifle system. The barrel is chambered on our HAAS TL-1 CNC lathe, threaded 5/8×24, laser engraved and Cerakote finished.
Barrel Blank MFG: Krieger
Caliber: 6.5 Creedmoor
Contour: AO Varmint (same as Rock Creek “Sendero” contour)
Muzzle: Threaded 5/8×24 with knurled thread protector
Color: Graphite Black
This is the same as Rock Creek’s “Sendero” contour, which is a medium sporter contour barrel with 1.250″ cylinder diameter and at 26″ would be ~.875″. By comparison a “Rem Varmint contour” is a sporter contour with 1.250″ cylinder and at 26″ is .830″. So this is just slightly heavier.
This is the barrel contour we use on our TMR and MARS rifles.
The barrel blank is a 416R SS blank with cut rifling.
