Sturm, Ruger & Company, Inc. (NYSE-RGR) proudly introduces three rifles chambered in Winchester’s all-new .350 Legend cartridge: two Ruger American Ranch rifles and one AR-556 MPR. These new rifles give hunters and shooters a variety of options to use this exciting new cartridge in both traditional bolt-action and modern sporting rifle configurations.

The AR-556 MPR has proven to be an excellent hunting platform, and the .350 Legend chambering expands that role. The nitrided 16.38” barrel is capped with a ½”-28 radial port muzzle brake. The rifle’s appeal is enhanced by the combination of a Ruger® Elite 452® AR-Trigger, Magpul® furniture and a 15” free-float handguard. Magpul M-LOK® accessory attachment slots make the addition of a sling or bipod easy. With less recoil, and weighing almost a pound less than its .450 Bushmaster counterpart, the MPR chambered in .350 Legend is a fantastic hunting option.

From the Ruger website:

There are also two ranch rifles.

Lower receiver is fitted with Magpul® MOE® grip and MOE SL® collapsible buttstock on a Mil-Spec buffer tube.

• Handguard is free-floated for accuracy and the slim, 15″ length provides enhanced ergonomics.
• Bolt is mil-spec 9310 and is machined and shot peened for strength and durability.
• The Ruger® Elite 452® AR-Trigger is a two-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull. It features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a faster lock time for improved accuracy.
• Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions with additional slots on the angled faces near the muzzle.
• Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The threaded barrel allows for standard muzzle accessories to be installed.
• Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. Optimized feed ramp provides improved reliability, and the matte black nitrided finish provides corrosion resistance.
• Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability.
• Bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing.
• Pistol-length gas system provides smoother operation and reduces felt recoil.
• Also includes: one magazine.

I was a bit surprised to see the pistol-length gas system, but I guess they’ve found that it contributes to the most reliable feed.  I’ll also comment that the price-point is right ($1099 MSRP).

Now.  I’d like to see a little better ammunition availability.
