What price range?
Can get drag bags from $30 to $1500 if money is no object the new Eberlestock drag bag is amazing, DS tactical carries them. If it is an issue one of the $100-$200 range ones work (voodoo,AIM,Condor).
If you have a cheap scope wouldn't worry, if you have a high end scope I wouldn't worrie outside of lense covers. If you have a high end scope you want kept as a safe queen range showing off scope. A scope sock is sufficient. If you want to spend money lots of companies make custom neoprene covers for scope transport.
Personally, I use an aim soft case, has back pack style ability or handle, enough padding I don't worry once the rifle is strapped in and enough storage that it can eliminate the need for a range bag or extra back pack in the woods.
Good luck.
