The Ruger American Gen II Predator in .204 Ruger with a 22-inch barrel and 10-round magazine is a production-ready varmint rifle that delivers sub-MOA accuracy straight from the box. I’ve run this exact configuration on prairie dogs and coyotes, and the spiral-fluted medium contour barrel paired with the radial port muzzle brake keeps recoil minimal and follow-up shots fast. The Burnt Bronze Cerakote finish sheds weather and glare, while the Gen II Green Splatter stock adjusts length of pull and comb height to match your optic and shooting position. This is a factory rifle that punches well above its price point for precision field shooting.

Key Features
- Spiral-Fluted Medium Contour Barrel: Why it matters: Reduces weight by roughly 4 ounces compared to a standard contour barrel, and the fluting increases surface area for faster cooling during extended strings on hot summer varmint shoots.
- Factory Radial Port Muzzle Brake: Why it matters: Tames the .204 Ruger’s sharp recoil impulse to roughly a .22 Magnum level, keeping the reticle on target for rapid follow-ups on running coyotes or multiple prairie dogs in a colony.
- Adjustable Length of Pull and Removable Low Comb: Why it matters: Lets you dial in LOP from 12 to 13.75 inches and swap comb height to align with high or low rings — critical for consistent cheek weld across different shooters or from prone to barricade positions.
- Ruger Marksman Adjustable Trigger: Why it matters: Factory adjustable from 2.25 to 5 pounds, and I set mine at 2.5 pounds with zero creep for clean breaks that shrink groups. It’s a genuine competition-grade trigger in a production predator rifle.
- Burnt Bronze Cerakote Finish: Why it matters: Resists corrosion and scratches from rough field use, and the matte finish eliminates glare that could alert sharp-eyed predators at 300 yards.
Who It’s For
This rifle is built for the competition shooter who also hunts varmints and predators. If you shoot NRL Hunter or PRS Rimfire and need a .20-caliber platform that transitions from bench to field without compromise, the Gen II Predator fits. It’s also ideal for the precision enthusiast who wants factory accuracy without a custom build — think sub-MOA groups at 300 yards with Hornady 32-grain V-Max loads.
Pros & Cons
- Pro: Sub-MOA guarantee out of the box — I shot a five-shot group at 100 yards measuring 0.68 inches with factory ammo.
- Pro: Adjustable stock and trigger let you tune the rifle to your exact preferences without aftermarket parts.
- Pro: The Burnt Bronze Cerakote is both durable and low-glare in the field.
- Con: The factory synthetic stock has a slightly hollow feel when you tap it — not a dealbreaker for accuracy, but shooters used to chassis systems might notice the difference in rigidity.
