Ah yes, the 7fingers stock with a right/right target action. Doesn't get much more exotic than that.
As everyone has said, you can go stock, mid or rear trigger, change barrels to any caliber.
My biggest criteria is always the availability of factory ammo, as I shoot with factory calibers.
My vote, box stock Striker in 7-08 and 140gr ammo. Add a Burris 4-12 EER scope, and you're set. May not be pretty, but it'll get bacon. Trigger can be adjusted to a reliable crisp 2lb, great for hunting. You get one in the pipe, 2 in the mag. Weighs in under 6 pounds and gets you in the field shooting.
Want to get more, add a mid length bipod for pack hunting sitting, and a comfortable sling.
Want to upgrade, McGowen has a great deal for Striker owners and you can get up to 17" any contour, any caliber listed, chambered and crowned for $210, I believe. Basic stock can be opened to light varmint contour easily. Or get a Savage factory barrel and lop it off and crowned, works great. New rifle barrels from NSS for about $85. And you can do it yourself with a barrel wrench, action wrench, and go gage.
Want to spend more. Add a fancy stock from several sources. Joel Russo is my favorite.
Want to upgrade more, get a nice rear grip stock like 7fingers and a rifle trigger.
Your $$$, your gun. Ernie is the guru.
