New to rim fire and just do regular precision rifles. Decide to get me a TB takedown 22 can while back and while waiting get me a 22 trainer. So savage mk II 22 TR with the tacticool stock with a little rattle can on it, luckily already fluted and threaded. Just added EGW rail and scope. Any input on upgrades would be appreciated with anyone who has some experience with gun and also subsonic ammo would be appreciated. Thanks fellows!
