Hey guys! Just wanted to say thanks in advanced already for any help. So i am set on buying a bolt action .17HMR with a synthetic stock. Now my question is what are the differences between the models for the synthetic stocks? Specifically, what are the differences between the XT-17VR, XT-17R, and XT-17SR? My goal is to get the model that will allow me to shoot the farthest distance accurately, and i plan on shooting some pidgeons, ground squirrels, etc. I would assume that is one with a bull barrel, but the main marlin site is unclear (to me atleast) on which one that is. So if anyone could tell me the differences, that would be great. thanks again!
