E. Remington & Sons manufactured approximately 5,000 Keene magazine rifles (in all configurations) between 1880-1883. This model was the first magazine fed rifle produced in quantity by Remington. A tubular magazine and carbine style forward barrel band like those used on classic lever action saddle ring carbines and many shotguns is fitted below the barrel that is loaded using a loading gate at the bottom of the action much like standard slide action shotguns. The hammer at the back of the bolt must be manually cocked for each shot. Production was limited in part due to competition with the Winchester-Hotchkiss rifles as well as the more modern Remington-Lee. They were used by the Indian Police and others in the West in the late 19th century. Features a straight grip stock and round barrel with fixed front and folding ladder rear sights. The bolt has the Remington address and Keene patent markings, and the "45/70" caliber designation is marked on the left of the receiver.

Fine as lightly Western used, retains 60% original blue finish with brown patina on the balance and light scattered freckling. Muted traces of original case colors on the hammer and rear barrel band. Stock is also fine with defined edges and some pressure dents and scratches concentrated around the left side of the buttstock. Mechanically fine.
