Medium-contour (.75" 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.
Ruger Precision MSR stock with QD sling attachment points features a bottom Picatinny rail and soft rubber buttpad. The left-folding stock hinge is attached to an AR-style buffer tube and accepts any AR-style stock. Length of pull and comb height are adjustable.
Cold hammer-forged, chrome-moly steel barrel with 5R Rifling at minimum bore and groove dimensions, minimum headspace and centralized chamber.
15" aluminum free-float handguard features Magpul® M-LOK® slots on all four sides for improved scope clearance for long-range scopes and easy mounting of M-LOK-compatible rails and accessories.
Ambidextrous manual safety for left- or right-handed lever manipulation.
20 MOA Picatinny rail secured with # 8-40 screws for increased long-range elevation capabilities.
"Upper" receiver and one-piece bolt are precision CNC-machined from pre-hardened 4140 chrome-moly steel to minimize distortion.

Barrel can be replaced easily by a competent gunsmith using headspace gauges.
Magazine well front is contoured for a positive grip when bracing against shooting supports.
Oversized bolt handle for positive bolt manipulation, with a 5/16"-24 thread pattern for easy replacement. Bolt disassembly tool is stored in the Ruger Precision Rifle Billet Aluminum Bolt Shroud for easy striker channel cleaning.
"Lower" magazine well halves are precision machined from aerospace-grade 7075-T6 aluminum and are Type III hard-coat anodized for maximum durability.
Extended trigger-reach AR-style grip and 45° ambidextrous safety selector. May be configured with any AR-style grip and selector.
