About this product
The Savage B22 Magnum FV-SR is a suppressor-ready bolt-action rimfire rifle chambered in 22 WMR, engineered specifically for precision varmint control and extended-range rimfire shooting. It features a heavy 16.25-inch threaded barrel and Savage's proven AccuTrigger system. This platform delivers consistent sub-MOA accuracy when paired with quality optics and ammunition.
What is the Savage B22 Magnum FV-SR used for?
This rifle excels at varmint hunting and precision rimfire practice out to 150 yards. Its 22 WMR chambering delivers 40% more muzzle energy than standard 22 LR, while the threaded heavy barrel maintains consistent harmonics when suppressed. The 10-round rotary magazine provides reliable feeding during extended shooting sessions.
How does the Savage B22 Magnum FV-SR compare to the Stevens 334 Rifle?
The B22 Magnum fires rimfire 22 WMR cartridges while the Stevens 334 handles centerfire .308 Winchester rounds. For precision small game hunting under 200 yards, the B22 Magnum offers lower ammunition costs at approximately $0.35 per round compared to $1.25 for .308. The Stevens 334 platform better serves medium-game hunting at extended ranges.
What does it weigh and what are the dimensions?
The complete rifle weighs 5.8 pounds with an overall length of 36.5 inches. The 16.25-inch barrel features 1/2x28 threading for direct suppressor mounting without adapters. The synthetic stock measures 13.75 inches length of pull with a 1.5-inch raised comb height for optimal optics alignment.
Who is this NOT for?
This rifle isn't suitable for hunters requiring centerfire power for deer-sized game or those needing rapid follow-up shots. The bolt-action design limits sustained fire rates to approximately 12 rounds per minute compared to semi-automatic platforms. Consider the Stevens 334 in .308 Win for larger game applications.
What's in the box?
The package includes the complete rifle, one 10-round rotary magazine, and standard paperwork. Unlike some competitors, Ironclad Armory includes thread protectors and mounting hardware for all threaded barrels at no additional cost. The receiver comes pre-drilled and tapped for #6-48 scope mounting screws.
Is the Savage B22 Magnum FV-SR worth it at $373.99?
At this price point, it delivers exceptional value for precision rimfire enthusiasts. The combination of AccuTrigger adjustability, suppressor-ready threading, and reliable rotary magazine system would cost $150 more in competing platforms. For hunters transitioning from shotgun platforms to precision rimfire, this represents an ideal entry point.
