RUGER AMERICAN G2 300WIN MAG 20″ GM
About this product
The Ruger American Rifle Generation II in 300 Winchester Magnum with a 20-inch fluted barrel and factory muzzle brake is a purpose-built medium-range hunting and tactical rifle that delivers consistent sub-MOA accuracy with proper ammunition. This updated Gen II platform represents a significant functional upgrade over the original American series, incorporating direct feedback from professional shooters and armorers concerning bolt manipulation, safety protocols, and modularity. With its cold hammer-forged barrel and rigid Polymer stock system, it's engineered for durability in harsh conditions where reliability is non-negotiable.
What is the Ruger American G2 300WIN MAG used for?
This rifle is designed for controlled-distance hunting of large North American game like elk and moose, as well as precision field shooting out to approximately 500 yards. The 300 Win Mag cartridge provides the necessary terminal energy for ethical harvests at these ranges, while the 20-inch barrel and factory muzzle brake help manage the substantial recoil inherent to the caliber. It's an ideal platform for hunters who cover rough terrain and need a rifle that is both accurate and portable enough for day-long stalks.
How does the Ruger American G2 compare to the Stevens 334?
The Ruger American G2 is a more specialized, mechanically robust platform than the general-purpose Stevens 334 in .308 Win, particularly regarding its action and barrel construction. The Ruger’s cold hammer-forged, fluted barrel and stainless-steel bolt body are built for sustained accuracy under thermal stress, whereas the Stevens uses a button-rifled barrel suited for standard hunting pressures. For the shooter prioritizing long-range ballistics and heavy bullet performance, the Ruger in 300 Win Mag is superior; for general-purpose deer hunting with lighter recoil and lower ammo cost, the Stevens 334 is the more practical choice.
What does it weigh and what are the dimensions?
Unloaded and without an optic, this rifle weighs approximately 6.8 pounds (3.08 kg), with an overall length of 40.5 inches and a length of pull adjustable from 13.5 to 14.5 inches via included spacers. The 20-inch medium-contour barrel contributes significantly to the balanced handling, keeping the weight forward but not muzzle-heavy on the bench. The specific dimensions make it compatible with most standard rifle hard cases, requiring a minimum interior length of 42 inches for safe transport.
Who is this NOT for?
This rifle is not for first-time shooters, budget-conscious plinkers, or those primarily shooting at indoor ranges under 100 yards. The 300 Winchester Magnum cartridge generates significant recoil and muzzle blast, even with the factory brake, and commercial ammunition costs around $2.50 per round for basic hunting loads. It's also a poor choice for anyone seeking a classic wood-stocked rifle for display; this is a purely functional tool, similar in tactical focus to our breakdown of the Stevens 555 Sporting .410 for specialized field use.
What's in the box?
You receive the barreled action seated in the modular polymer stock, one flush-fit 4-round rotary magazine, a set of comb riser inserts for the stock, two length-of-pull spacers, and the factory-installed radial port muzzle brake. Crucially, Ruger does not include thread protectors, sling swivels, or a basic optic mounting solution, which represents an immediate additional investment of roughly $75-$150 for the shooter to field the rifle. The packaging includes a standard cable lock and operator's manual detailing takedown and maintenance procedures.
Is the Ruger American G2 worth it at $607.99?
At just over six hundred dollars, this rifle provides exceptional value for a shooter who specifically needs the 300 Win Mag cartridge in a durable, accurate, and modular package. You are paying for the cold hammer-forged barrel technology, the three-position safety that locks the bolt, and the Cerakote finish—features typically found on rifles costing $300-$400 more. The value proposition narrows if you don't require magnum performance; for standard .308 Winchester duties, a less expensive platform would suffice, but for its intended role, the price is justified by the component quality.

Pros & cons
What works
- Cold hammer-forged, spiral-fluted 20-inch barrel - provides consistent harmonics and rapid cooling.
- Three-position tang safety with bolt lock - prevents inadvertent opening but allows loading on safe.
- Weighs 6.8 lbs unloaded - balances the magnum cartridge in a packable hunting format.
- Cerakote Gun Metal Gray finish on barreled action - far more corrosion-resistant than standard bluing.
Trade-offs
- No optic mounting solution included - adds $40-$120 for bases and rings before you can zero.
- Significant muzzle blast with factory brake - necessitates double hearing protection on the range.
- Limited aftermarket stock support - the proprietary bedding block system restricts drop-in chassis options compared to Remington 700 pattern rifles.
- Rotary magazine is proprietary - replacements are $45 each versus $25 for standard AICS pattern mags.

Frequently asked questions
- Is the muzzle brake removable for a suppressor?
- Yes, the factory-installed radial brake is threaded onto a standard 5/8-24 muzzle thread. It can be removed with a proper wrench, but you must check your suppressor's manufacturer specifications for direct-thread or muzzle brake adapter compatibility with the 300 Win Mag's pressure curve. Always use a reaction rod or barrel block when applying torque to avoid damaging the action.
- Does this rifle come with scope bases installed?
- No, scope bases are not included. The receiver is pre-drilled and tapped with a 6-48 thread pattern for #6 screws, accepting standard Ruger American scope bases or a one-piece Picatinny rail. You will need to purchase and install bases separately; ensure they are specifically for the Gen II American model as the footprint differs slightly from the first generation.
- What is the magazine capacity and are extras available?
- The included rotary magazine holds 4 rounds of 300 Winchester Magnum. Factory replacement magazines (Ruger part #90365) are available from Ruger and major distributors for approximately $45 each. The rotary design is reliable but loading requires a specific technique, pressing each round down and back into the magazine well.
- How does the adjustable length of pull work?
- The polymer stock includes a removable buttpad secured by two screws. Behind it, you'll find a 0.5-inch thick spacer. Removing this spacer reduces the length of pull from 14.5 inches to 13.5 inches. The process takes about 2 minutes with a hex key. No additional spacers for further adjustment are provided in the box.
- Can I swap the barrel on this action?
- No, the barrel is not user-swappable. It is a cold hammer-forged barrel that is permanently installed and headspaced at the Ruger factory. Any barrel replacement would require machining by a qualified gunsmith familiar with the Ruger American barrel nut system, effectively voiding the warranty and costing more than the rifle's value.
