Heavy-contour (.850" at the muzzle) barrel features a Ruger Precision Rifle Hybrid Muzzle Brake to effectively reduce recoil while minimizing noise and blast to the sides of the shooter.

Patented multi-magazine interface functions interchangeably with AICS and M110/SR-25/DPMS/Magpul-style magazines (works with some M14 magazines).

Ruger Marksman Adjustable™ trigger is externally adjustable, with a trigger pull range of 2.25 to 5 pounds; wrench is stored in the bolt shroud.

In-line recoil path manages recoil directly from the rear of the receiver to the buttstock, not through a traditional bedding system, providing maximum accuracy potential.

Buttstock allows for easy, intuitive and secure adjustment to conform to any shooter or style and is adjustable for length-of-pull; cheek rest height and horizontal position; as well as buttpad height.

"Upper" receiver and one-piece bolt are precision CNC-machined from pre-hardened chrome-moly steel to minimize distortion.
