Remington Model 550-1 .22 LR Semi-Automatic Rifle, 24" Blued Barrel, 1950 Production
Produced in 1950, this Remington Model 550-1 showcases David "Carbine" Williams’ floating-chamber design, allowing it to cycle .22 Short, Long, and Long Rifle cartridges interchangeably. A 24" blued barrel, 15-round tubular magazine, and hardwood stock combine to deliver a classic mid-century rimfire that remains functional despite clear evidence of field use.

What’s Included
- Remington Model 550-1 rifle
- Clip-on shell deflector (installed)
The Model 550-1 sits between the wartime 550A and the later Model 552, reflecting Remington’s post-war evolution of its rimfire line. Lack of a serial number confirms pre-1968 manufacture, typical for rifles of this era.
Williams’ floating-chamber principle redirects gas to give the bolt extra energy, enabling reliable blowback operation with any .22 rimfire length without manual adjustment. This versatility made the 550-series popular for plinking, small game, and training.
The 24" carbon-steel barrel carries a 1:16 twist for standard .22 LR bullets. A dovetailed blade front sight pairs with a drift-adjustable rear notch; only the elevator piece is absent. The factory clip-on shell deflector protects left-handed shooters from ejected cases.
A full-size hardwood stock with an oil finish provides a 13.75" length of pull. Controls are straightforward: a manual thumb safety and traditional bolt handle. Magazine capacity is 15 rounds of .22 LR (or 22 Shorts/Longs) in the under-barrel tube.
