The Remington 870 is an American made pump (slide) action shotgun that is bottom loading and side ejecting, and has a tubular magazine and twin action bars. The 870 is Remington's 4th major shotgun design, and is hands down the most popular, being the best selling shotgun of all time. It was introduced in 1950 as the Wingmaster model. The design has not changed since it's introduction and it is still widely known for it's dependability and ruggedness, as well as being reasonably priced. It has served the U.S. military and law enforcement for many years, as well as being heavily used by hunters and clay pideon shooters.
The Wingmaster model comes with a polished blued finish and a glossy walnut stock. In 1996 the Express model was introduced. The Express is the same gun, with less cosmetics, coming with a matte black finish and a stained hardwook stock. The Marine model comes with electroless nickel plating and a synthetic stock and the police models feature a parkerized finish with either hardwood or sythetic stocks. The 870 is also offered in jr. sizes and a Classic Trap model.
Your greatly designed Remington 870 shotgun will surely outlast you and be used by your children and your children's children.
