The Proof Research 6.5 Creedmoor carbon fiber pre-fit barrel for Defiance-pattern actions (brand part number 123171) is a 22-inch Sendero-contour barrel machined to drop onto a Defiance receiver. It is wrapped from aerospace-grade carbon fiber over a 416R stainless steel liner, cutting weight by as much as 64 percent versus a comparable steel barrel. Pairing 6.5 Creedmoor’s flat trajectory with a proven custom Defiance action is a popular combination for long-range hunters and precision shooters looking to shed weight without giving up accuracy.
