The Marlin Model 70P, also known as the Marlin Papoose, is a .22 Long Rifle semi-automatic rifle manufactured by Marlin Firearms. The rifle is notable for its portability; it is less than 21 inches (530 mm) in length when disassembled and weighs 3.25 pounds. Disassembly requires loosening a barrel retention nut by hand or with a supplied tool. It is designed as a hiker and camper utility rifle, and appeals to the same market as the AR-7.
