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″ is ~.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. We use blanks from our inventory of premium barrels from manufacturers including Rock Creek, Brux and Kreiger. Specific blank manufacturers are available upon request.
