You are looking at spending $600 at least for a good scope.
I am not sure if timney makes a trigger for the atr, but if they do it would probably be a few 100 s to get it here and installed.
Maybe a talented gunsmith could look at you gun and reduce the original trigger pull down to say 3 or 4 pounds. You would be looking at 1 to 2 hrs of work I guess.
I would upgrade the scope first if it was me.
Because your cheap scope might let you down at the most critical moment, not your trigger.
And if you end up selling the gun, you can keep your good scope for the next gun.
See what the others have to say.
