I have 2 options for ya.
option 1 If you want an excellent trigger, Larue MBT. its about $80.00 direct from larue. I got a 2 stage trigger, 4.5lb total 2.5lb take up, with a 2lb break. However my trigger scale says its a flat 2.5lb. it does come with a heavier trigger spring that might bump it up a tad if you feel its too light. clear crisp break, never had a light strike. the trigger return does feel light/sluggish with the lighter spring.
Option 2 JP enhanced reliability spring it. its about $11.00 off midway usa It is intended to take a mil spec 6.5lb trigger down to 4.5lb. in my experience factory triggers are usually about 8-8.5lb and have a lot of grit and creep and are terrible. I have used the JP spring kit on a couple rifles now. It has reduced the pull by about 2lb, bringing the guns to the 6-6.5lb range and got rid of almost all the grit and creep. For the money I think it is an amazing value and makes a huge difference.
option 3, sort of. I did try the PSA enhanced nickel plated polished trigger group several years back, cant find it on their site anymore, I think it was about $25. the results were not impressive. they were an improvement over a mil spec group, but the results were about the same as the JP spring kit. 6is lb pull, got rid of almost al the grit and creep. Not worth it in my opinion.
If it were me, and your budget it $120 or less, and I wanted a GOOD trigger, the Larue hands down.
