Why this product

The verified differentiators — carbon fiber wrapped barrel construction, Sendero contour, explicit breech and shank dimensions, and a supplied package quantity of four — matter when you are planning barrel installations, inventory stocking, or batch builds. The carbon fiber wrapped construction and Sendero contour are identifying attributes that help match the blank to specific build specifications; the 2.5″ breech and 1.20″ shank are critical reference dimensions for chambering and fitting.
