This Remington Model 550-1 stands out for its Williams floating-chamber system that allows reliable operation with .22 Short, .22 Long, and .22 Long Rifle. It features a 24-inch barrel, under-barrel tubular magazine with a stated 15-round capacity, and classic iron sights. A Pronghorn-branded riflescope is installed, adding ready-to-use versatility alongside the factory sights.
The rifle is a steel, blued semi-automatic with right-side ejection and a right-side charging knob, paired with a wood stock and a checkered steel buttplate marked Remington.

The Model 550-1 uses a semi-automatic blowback action enhanced by a Williams floating-chamber design, letting the shooter run .22 Short, .22 Long, and .22 LR interchangeably. This multi-cartridge capability is a defining feature of the 550-series and adds flexibility for varied ammunition.
Its 24-inch barrel and under-barrel tubular magazine provide a stated 15-round capacity, with right-side ejection and a right-side charging knob for familiar handling. The steel receiver and overall blued finish deliver a traditional appearance consistent with Remington’s rimfire lineup.
Sighting options include a fixed front blade on a low ramp and an open rear sight with a stepped elevator for elevation adjustments. The included Pronghorn riflescope is installed in rings, offering an immediate optic solution alongside the iron sights.

Made in the USA, the Model 550-1 represents a long-running American rimfire pattern. Within the 550 family, many examples produced before 1968 were not serialized, reflecting the era’s manufacturing norms.
