Anyone adjusted there trigger on there FN SPR? I have the instructions on how to do it. I liky my overtravel the way it is. I only want to adjust the trigger weight as I am getting 5 to 5.5 lb readings on the rcbs spring trigger scale while the stock is on. I have got a few 4.75 readings but think avg is above 5 lbs and want it no less than 3 lbs and prefer like 3.25 to 3.50 as just a incase it drops down some over time from use. I put almost 400 rds in the rifle so trigger should be well broke in. any pics anywhere? Can I just unloosen the weight jammed nuts only and not all 3?
