Remington Model 550-1 .22 S/L/LR Semi-Automatic Rifle – 24" Barrel, Tubular 15-Round Magazine
Remington’s Model 550-1 is a post-WWII rimfire that stands out for its Williams floating-chamber system, allowing it to cycle .22 Short, Long, and Long Rifle rounds interchangeably. Built with a 24" carbon-steel barrel and a reliable under-barrel tubular magazine, this mid-century autoloader offers versatile rimfire performance in a classic walnut-stocked package.

What’s Included
- Remington Model 550-1 .22 S/L/LR semi-automatic rifle
Designed between 1946 and 1970, the Model 550-1 embodies Remington’s mid-century craftsmanship, with approximately 730,000 examples produced. This rifle was built before 1968 and therefore carries no serial number, a common trait of its early production run.
The floating-chamber design creates a brief delay in bolt movement, giving the blow-back action enough energy to reliably run everything from quiet .22 Shorts to high-velocity .22 LR. A riveted shell deflector atop the receiver adds convenience by directing spent cases away from the shooter.
The 24" carbon-steel barrel features a 1:16 right-hand twist for consistent bullet stability. Open iron sights include a dovetailed front blade and elevator-adjustable rear leaf, making target adjustment straightforward.
Walnut furniture, with a grooved fore-end and 13.5" length of pull, delivers a traditional look and comfortable handling. The blued receiver and barrel round out a rifle that balances vintage appeal with everyday shooting utility.
