The factory rings that come w/ the tikka arent fit for a cheap pellet gun, and I dont think its drilled and tapped for standard mounts. I also think the magazine sucks, although others seem to like it.
IMO, all injection molded stocks are ugly and flimsey, savage are no worse than tikkas. IMO the best inection molded stock is on the 700SPS, but they are all just utilitarian, not suppposed to be pretty. The savage accutrigger is great, and not the hassle some think it is. I can shoot just as quick w/ my 10ml as my 700. For the same price I would take a blued xbolt , or 700 sps stainless over a tikka.
