Christensen Arms Mesa Long Range .300 Win Mag Bolt-Action Rifle - Black

The Christensen Arms Mesa Long Range .300 Win Mag is a precision bolt-action rifle built for hunters and shooters who demand accuracy at distance. Christensen Arms engineered this rifle around a stainless steel barrel and adjustable composite stock specifically for long-range performance, pairing proven Rem 700 platform mechanics with modern ergonomics and materials designed to handle magnum recoil and deliver consistent sub-MOA accuracy shot after shot.

Built on a skeletonized Rem 700-style action with a Trigger Tech trigger, the Mesa Long Range features a medium palma contour 416R stainless barrel hand-lapped and button rifled for precision, free-floating in the stock to eliminate pressure variables. The barrel is threaded 5/8x24 and wears a removable seamless side-baffle muzzle brake that you can take off if your hunting situation calls for it. Christensen Arms' match chamber ensures reliable feeding and firing across quality .300 Win Mag ammunition.

The carbon fiber composite stock is adjustable for length of pull and comb height via spacers, letting you dial in fit and cheek weld for your optic and shooting style. Stainless steel pillars and spot bedding keep the action stable, while the tungsten Cerakote action finish and black stock with gray webbing give the rifle a professional, purpose-built look. At a starting weight of 8.9 pounds, the Mesa Long Range is manageable for field hunting while staying rigid enough for precision work. The rifle ships with a 4-round (.300 Win Mag) internal magazine and hinged floor plate, twin lug spiral fluted bolt, and dual ejectors tuned for magnum cartridges. Every Mesa Long Range is backed by Christensen Arms' Sub-MOA Guarantee.
