HKLVR, You do not mention what the current pull weight of your trigger is but I will tell you that if it is much over 7 lbs. something could be wrong. I just measured,
as in with a scale , several
homemades with untouched triggers as well as a Colt Delta HBAR. Delta was 5.5 and the worst kit gun was 6.75.
The best parts gun with stock trigger components, lightly shined up and well lubricated came in at 5.25. If this is good enough for you it can be done easily.
If you would rather spend some money and still need to tinker a bit the first Jewell I picked up went 2.75 and after looking at which rifle it was I can say that I like it. I found one rifle with an Accuracy Speaks trigger set and it went 3.25 and is a single stage trigger.
The Jewell is easy to set up if you have very good eyes and eye hand coordination. My eyes are not that great anymore but I can still do it. This trigger, IMHFO should be used on a recreational rifle.
The Accuracy Speaks is in a favorite target rifle of this variety. It is a very easy job to install one of these but you must expect to do some work on the geometery of the disconnector with helpful input from the maker BTW.
The only thing about a light single stage trigger on a semiautomatic rifle is that your finger might get in the way after the next round is in battery from time to time.

HKLVR, You can get a good 6 lb. or a little less with no cost and very little work.
