The Kelbly Long Nanook Receiver is designed to be the best hunting application action for a Remington 700 footprint stock. All integral features including a skeletonized MIL-SPEC Picatinny rail, full skeletonizing of the body to reduce weight by 7 ounces, a .250" recoil lug, anti-shear bolt stop design and the ability for any existing Atlas barrel to directly fit the tenon. Finished in Black Nitride for increased slickness and corrosion resistance in extreme environments. Only available with an ADL/BDL extended magazine cutout (Wyatt's MBE-3 on long actions).
