Mark II FV-SR owners typically buy the rifle with suppressor use in mind, and most report it runs reliably with a wide range of .22 LR ammunition once the barrel is broken in. The threaded, fluted barrel setup is the main draw, and it delivers on that premise without fuss.

The trigger on the Mark II draws honest opinions. Some shooters find it adequate for plinking and small-game use; others upgrade it relatively quickly, citing a heavier pull than they wanted. The synthetic stock is functional rather than refined, and a few owners note some flex at the grip under hard use.

For the price, the FV-SR is generally seen as a practical package. It doesn't compete with higher-end rimfire platforms on fit and finish, but buyers who wanted a ready-to-suppress bolt-action .22 LR without spending on a custom build tend to walk away satisfied. Those expecting match-rifle precision out of the box have occasionally been let down.
