The Rock River Arms BT3 X-Series 308 is engineered for shooters who demand consistency at the range and reliability in general-duty roles. Its blend of precision components and practical ergonomics makes it a strong candidate for long-range practice and match competition where repeatable accuracy and manageable recoil are priorities.

ROCK RIVER ARMS, INC. BT3 X-SERIES 308 delivers an 18″ fluted stainless steel barrel with a 1:10 twist and Hunter muzzle brake, optimized for .308 WIN loads and heavier match bullets.

Key features and what they mean on the range

The BT3 X-Series includes a 17″ lightweight free-floating M-LOK handguard that allows for modular accessory placement without impacting barrel harmonics. The free-float design helps maintain consistent groups by isolating the barrel from pressure points. The RRA Two Stage Ultra Match trigger provides a predictable break and crisp reset, essential for tight follow-up shots during timed stages.

Its mid-length gas system and 6-position Operator CAR stock balance recoil management and shooter comfort. At 8.7 lbs unloaded, the platform is stable from the bench yet still maneuverable for practical drills. The rifle ships with a single 20rd magazine, suitable for range sessions and competition formats that allow larger capacities.

Caliber and ballistic considerations

Chambered in .308 WIN, the BT3 X-Series leverages a proven, versatile caliber favored for precision shooting, hunting, and competition. The 1:10 twist rate stabilizes a wide range of bullet weights, making the rifle adaptable from lighter match bullets to heavier hunting projectiles. The Hunter muzzle brake reduces perceived recoil, helping maintain sight picture and improving follow-up shot speed.

Fit for purpose: range and competition

Whether building a load for sub-MOA groups or dialing in for a tactical precision match, the rifle’s combination of barrel profile, trigger, and adjustable stock creates a platform that’s easy to tune for individual shooters. As a Bolt Action entry in Rock River Arms’ lineup, it reflects the brand’s focus on craftsmanship and repeatable performance.
