The 10/22 Competition features a texturized laminate stock with an adjustable cheek rest that's easily adjusted for comb height or forward/aft position to align your eye perfectly with your sights. The hard-coat anodized, CNC-machined receiver is made from heat-treated and stress-relieved 6061-T6511 aluminum, and features a 30 MOA Picatinny rail for mounting optics and other rail-mounted accessories. The receiver incorporates a rear cleaning port, allowing you to clean the barrel from the breech, while a proprietary enhanced semi-auto chamber increases accuracy without compromising reliable feeding and extraction. A heat-treated and nitrate-coated, CNC-machined match bolt creates a tight-fitting, smooth action, and the cold hammer-forged and fluted bull barrel is threaded (1/2"-28) to accommodate a muzzle brake (included), suppressors, and other aftermarket accessories. The Ruger 10/22 Competition Semi-Auto Rimfire Rifle incorporates a unique dual bedding system, with a second bedding lug, to ensure the receiver is securely bedded to the stock for maximum accuracy potential. A BX-Trigger(TM) boasts a crisp, clean break at 2.5-3 lbs., with minimum overtravel and a positive reset. Uses standard 10/22 magazines.
