What type of scope is it?

You really have 3 options.

1. Once you have the new stock, maybe the scope will work ok as is.
2. Get an extended ring so you have the room to slide the scope forward.
3. Get a different scope.

Re: trigger...certainly you can have it adjusted / lightened, but 2lbs "may" be too light. I think most folks prefer around 2.5. The problem when you go too light...some rifles can fire if you slam the bolt (ie: cycle it fast and hard). Certainly don't want that to happen.
