Stainless steel barrel is precision machined to match-grade tolerances and custom-fit to its own bolt to give your rifle the exceptional accuracy of a custom-shop barrel in a drop-in package. Each barrel is assigned a bolt before any machining begins, then chambered to the correct headspace for that bolt. Button rifled for superior land-to-groove dimensions required for match-rifle accuracy, with a recessed 90° target crown, and gas block shank machined to .001" tolerances for precise fit. Comes with M4-style barrel extension installed; extension has pre-cut feed ramp to help ensure reliable chambering of rounds. Available chambered in .204 Ruger with 24" heavy varmint/target barrel or .223 Wylde with 20" service-rifle contour barrel. Wylde chamber delivers enhanced accuracy and reliability with the widest variety of .223 or 5.56 NATO ammunition.
