Consignment Custom .300 Win Mag Rifle – Left Hand

Hard-to-Find Left-Hand Custom Rifle. Premium Components. Proven Accuracy. Exceptional Value.

This custom left-hand .300 Win Mag is a purpose-built long-range hunting rifle assembled with premium components throughout. Quality custom left-hand rifles can be difficult to find, making this an excellent opportunity for a left-handed shooter looking for a proven hunting platform without the cost and wait associated with starting a custom build from scratch.

Built around a Kelbly’s Stolle Atlas action and a 26″ Proof Research Sendero carbon fiber barrel, this rifle combines premium custom-rifle components with the performance and versatility of the proven .300 Winchester Magnum.

At an asking price of just $2,500, the value is difficult to overlook. By the time you purchase a premium custom action, Proof Research carbon barrel, composite stock, trigger, muzzle brake, and pay for the associated gunsmithing, bedding, and assembly, recreating a rifle of this level would typically cost considerably more.

The barreled action is fitted into a JCS Composites stock with an adjustable stock setup and has been glass bedded for a solid, consistent fit. A Timney Trigger provides a clean, predictable break, while the stainless steel 3-port muzzle brake helps reduce recoil and improve control for spotting impacts and follow-up shots.

The current owner states that this rifle shoots approximately 0.5 MOA with either Federal Premium 190-grain Terminal Ascent or Hornady 178-grain ELD-X factory ammunition—giving the new owner two proven ammunition options without immediately needing to develop a custom handload.
