Detailed Features 

 
The AccuTrigger has an internal blade that must be fully depressed before the main trigger breaks, which both prevents unintended discharge and allows the overall pull weight to be set lighter than most factory triggers without losing safety margin. This matters for precision rimfire work where trigger weight directly affects shot-to-shot consistency. 
 
The button-rifled heavy barrel at 16.25 inches is threaded for suppressors or muzzle devices. The heavier profile compared to a sporter barrel reduces harmonic movement during firing, which contributes to tighter groups over a session. 
 
The synthetic stock is resistant to weather and temperature changes, and at 6 lbs total the rifle carries well for a heavy-barrel design. 
 

Usage Scenarios 

• Small Game and Pest Control: .22 WMR has effective range and terminal performance on rabbits, squirrels, and varmints at distances where .22 LR loses energy. 
• Target Shooting: The AccuTrigger and heavy barrel suit competitive rimfire disciplines. 
• Suppressor-Ready Use: The threaded muzzle accommodates .22 WMR suppressors for hearing-safe practice.

The Savage B22 Magnum FVSR in .22 WMR gets strong reviews from rimfire shooters who want more range and energy than .22 LR can deliver. The AccuTrigger is the most consistently praised feature: users find the adjustability meaningful, and a properly set AccuTrigger compares well to triggers on rifles that cost significantly more.

Accuracy is a frequent highlight. Shooters report tight groups at typical .22 WMR distances, and the heavy barrel is credited with reducing the shot-to-shot variance that comes with thinner-profile rimfire barrels.

The synthetic stock gets practical marks for weather resistance, and the 16.25-inch threaded barrel suits owners who run suppressors.

On the negative side, some users report feeding or cycling issues with specific ammunition types, particularly certain hollow-point loads. This seems to resolve with ammunition selection in most cases. The aesthetic of the rifle draws mixed opinions; some owners find the utilitarian matte black synthetic look appropriate for a working gun, while others find competing options more visually appealing at similar price points. A few buyers expected tighter groupings given the heavy barrel profile and needed to experiment with ammunition to find loads that shot to spec.

Overall the B22 Magnum FVSR sits well in the mid-range .22 WMR bolt gun category, with the trigger and barrel combination being genuine differentiators.
