Heavy-contour (.875" at the muzzle) barrel features a Ruger Precision Rifle Magnum Muzzle Brake with tunable compensator to effectively reduce recoil and muzzle jump. 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. Ruger Precision MSR stock features a bottom Picatinny rail and soft rubber buttpad. The left-folding stock hinge accepts any AR-style stock. Length of pull and comb height are adjustable. Mfg: Ruger
