The Remington Model 552 "Speedmaster" is a semi-automatic rifle that can fire .22 Short, .22 Long and .22 long rifle cartridges. Ammunition is fed from a tubular magazine under the barrel. The model 552 features a unique low profile left-side bolt handle that lends itself to a clean receiver appearance and slender profile. The rifle was manufactured from 1957 to 1988 in a standard model and is available in an upgraded "BDL" model, which has checkered butt stock and forearm with a gloss finish. Also included is an open sight and a 3/8" (9.5 mm) dovetail rail for mounting a scope and a safety on the trigger guard. In 1966 Remington offered this rifle with a special stamping of the company's 150th anniversary on the left side of the receiver.
