The Model 550-1 is chambered for .22 Short, Long, or Long Rifle, with the barrel specifically marked ".22 SHORT, LONG OR LONG RIFLE." This flexibility is supported by the model's floating-chamber blowback design, which was engineered to handle the different energy levels of these rimfire loads.
It wears a 24-inch barrel and open sights, including a barrel-mounted blade front and an elevator-adjustable barrel-mounted leaf rear. The receiver is marked "MODEL 550-1" and has longitudinal ribs on top without 3/8 inch scope grooves.
This rifle feeds from an under-barrel tubular magazine with a removable inner tube and a listed capacity of 10 rounds. The length of pull measures 13.75 inches, providing a comfortable fit for many shooters.
The stock is hardwood with a semi-pistol grip, and this example has a replacement hard rubber buttplate featuring the Winchester Repeating Arms logo. Many Model 550-1 rifles were produced before 1968 and were not serialized, reflecting the era of manufacture for much of this model's production. Made in the USA.
