What's in the Box American Gen II Predator 6mm ARC Rifle (1) 10 Round Magazine Steel Swing Swivel Studs Owner's Manual Firearm Features Splatter finished stock provides excellent grip without being too sharp or abrasive. Soft rubber recoil pad features a large radius on the heel for easy shouldering and improved geometry that progressively collapses to reduce felt recoil. Removing the installed spacer allows for length of pull to be adjusted from 13.75" to 12". Installed low comb improves sight alignment when using magnified optics but can be removed when utilizing low-mounted sights. Professionally applied Cerakote coating on barrel, muzzle brake, receiver and bolt handle results in a durable, easy-to-maintain finish. Medium contour barrel features deep spiral flutes that reduce weight at the muzzle end of the barrel to improve balance without sacrificing stiffness or accuracy. Threaded barrel with factory-installed radial port muzzle brake is cold hammer-forged, resulting in ultra-precise rifling that provides exceptional accuracy and longevity. Intuitive three-position tang safety locks the bolt, preventing inadvertent bolt opening while allowing the rifle to be loaded with the safety engaged. Ruger Marksman Adjustable trigger offers a crisp release with a pull weight that is user-adjustable between 3 and 5 pounds. Patented Power Bedding integral bedding block system positively locates the receiver and free-floats the barrel for outstanding accuracy. The one-piece bolt is CNC machined from stainless steel for smooth operation and the familiar three-lug design with 70 throw provides ample scope clearance. Oversized bolt handle for positive bolt manipulation, with a 5/16"-24 thread pattern for easy replacement. Factory-installed, one-piece Picatinny scope base.
