I had the same issue you did. I have the RRA varmint trigger which uses factory 3.5 pound springs. Awesome trigger for $100. I have it on my spr, and it works great. I tried it in my carbine, and it was too light. I found myself tripping the trigger when my finger was resting on it. My solution was to use the ALG ACT trigger with 3.5 lbs JP springs, and a trigger adjuster screw I got for $5. Product was a super smooth (0 grit what so ever), short uptake and reset, and light trigger. I was able to ring steel at 300 with a red dot every second. There is a very clear break without being too light. With the standard trigger I was able to connect every 2 or 3 seconds at best. This is just my personal experience. Total price was $80. If thats too much for you, then the springs and adjuster are only $20. Try the springs and adjuster first. It eliminates the take up and heavy ass pull. There will still be some grit. Good luck to you, finding the perfect trigger pull is often a result of trial and error.
