Ruger 18016 Precision Rifle Bolt 6mm Creed 24 10+1

Specifications: Medium-contour barrel features a Ruger Precision Rifle® Hybrid Muzzle Brake to effectively reduce recoil while minimizing noise and blast to the sides of the shooter (thread protector included). Cold hammer-forged 4140 chrome-moly steel barrel with 5R Rifling at minimum bore and groove dimensions, minimum headspace and centralized chamber. 20 MOA Picatinny rail secured with four, #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. Three-lug bolt with 70° throw features dual cocking cams and a smooth-running, full diameter bolt body. 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. Equipped with a Ruger Precision Rifle® Short-Action Handguard for improved scope clearance for long-range scopes. Magazine well front is contoured for a positive grip for bracing against shooting supports. Oversized bolt handle for positive bolt manipulation, with 5/16"-24 thread for easy replacement. Bolt disassembly tool is stored in the 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. Patent-pending 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 pull weight range of 2.25 to 5.0 lbs.; wrench is stored in the bolt shroud. Extended trigger-reach AR-style grip and 45° reversible safety selector. May be configured with any AR-style grip and selector. Barrels can be easily replaced by a competent gunsmith using AR-style wrenches and headspace gauges. Also includes: two, 10-round Magpul® PMAG® magazines.
