Just got a MM tuned XS-25 SFB today. Borrowed a scope off my R7 and got it sighted in pretty close at 30 ft in the basement.[H&N FTT 8.64]. Trigger is great
Had the standard version in .22. With Mike's handiwork and his 2nd screw trigger mod, it was a real nice shooter, quiet, easy cocking and not too pellet picky.
It was gifted to a friend on another forum when I downsized my rifle collection.
