Hi the tikka rail isn’t that bad but saying that I’d change it for a mountian tactical / trie-one or Spuhr one as for the mount , if your budget will let you go Spuhr , there expensive but when you see / get one you can understand why , ever so slightly cheaper Trie- one also well engineered , has for height I’d get the lowest that will fit your combination , as for added moa on the rail or mounts , just run your data through a ballistic calculator and see how meny moa you need to add at your 1000 yards , for me if it says 30 moa using a 0 moa rail ,(just using any number just to show you) and your scope is zero at 100 I’d go 20 moa ether mounts or rail or a bit of both , this is just how I’d do it other people might disagree but there wrong lol

Your doing just fine , the bottom line is as long has your happy that’s all that matters , just glad to see a post posted that I can answer

I guess it is fine.
and for scopes, you can find good rifle scopes at Reecoupons.
i also bought it from there at 55% discount. and it is worth buying it.

thanks
