Frequently Asked Questions
What thread pitch is the barrel on the B22 Magnum FV-SR, and which suppressors are compatible?
The Savage B22 Magnum FV-SR features a standard 1/2x28 TPI threaded muzzle, which is the most common thread pitch for rimfire suppressors in the United States. This makes it compatible with a wide range of popular .22 WMR and multi-caliber suppressors from manufacturers such as Silencerco, Dead Air, and Rugged Suppressors. Always confirm suppressor compatibility with the manufacturer before purchasing.
How does the AccuTrigger work and how do I adjust the pull weight?
Savage's AccuTrigger is a user-adjustable trigger system that allows you to set the pull weight within a specified range — typically between approximately 2.5 and 3.5 pounds on rimfire models — without requiring a gunsmith. A small adjustment tool (included with the rifle) is inserted through the trigger guard to rotate an internal mechanism, lightening or increasing the pull to your preference. The AccuTrigger also features a built-in safety lever that prevents the rifle from firing unless the trigger is fully and deliberately engaged.
What is the effective range of the .22 WMR cartridge, and how does this rifle perform at distance?
The .22 WMR (Winchester Magnum Rimfire) is effective on small game and varmints at distances up to approximately 100–150 yards, with some shooters pushing it to 125 yards for precision target work. The B22 Magnum FV-SR's heavy button-rifled barrel helps maximize velocity consistency and minimizes barrel flex, contributing to tighter groups at distance. Pairing the rifle with quality 40-grain or 50-grain .22 WMR ammunition and a quality optic will allow you to take full advantage of the cartridge's flat trajectory and terminal performance.
