The Christensen Arms 7mm Backcountry 16″ Carbon Fiber/Stainless Steel Pre‑Fit Barrel (model 810‑00152‑00) is a high‑performance rifle barrel designed for custom builders and gunsmiths who want to maximize accuracy, reduce overall rifle weight, and maintain field‑ready versatility. At its heart is a precision‑machined 416R stainless steel core that has been button‑rifled and hand‑lapped for consistent chamber dimensions and tight group potential. Wrapped in lightweight aerospace‑grade carbon fiber, the barrel offers improved heat dissipation and reduced weight compared with traditional all‑steel barrels — a benefit especially noticeable during extended shooting sessions or long backcountry treks. With a 16″ length and a likely 1:8″ twist rate, it’s optimized for the efficient and high‑ballistic‑coefficient 7mm Backcountry cartridge, balancing velocity with manageability in a compact profile. The included thread protector safeguards the threaded muzzle until you’re ready to install a muzzle brake, suppressor, or other accessory, and the pre‑fit design ensures straightforward installation on compatible Remington 700 pattern actions. Whether building a lightweight mountain rifle or a precision hunting platform, this pre‑fit barrel puts Christensen Arms’ carbon fiber innovation at the core of your custom project.
