    Yes, I also stated that one had to at least have the concepts of geometry, and physics understood also. There are spring kits out there also, that are ok, but most of the time the sear/striker need to be stoned. Only someone who is competant can do this, or you can end up with an unsafe rifle. I usually reduce the amount of sear engagement, and slightly change the angle. I have made a jig for this purpose to help keep the stoned/polished surfaces square, and to the correct angle, and depth.

    I did notice the engagement surfaces were rough, and intended to polish these with a fine sand paper or polishing compound. Is a shorter spring the way to get a lighter trigger? if so, how are they measured, so I know what to order. Thanks

    no, not a shorter spring...the spring rate is what needs to be changed. A Dremel tool with a pollishing mandrel, and compound work well for smoothing machine marks, but be advised, this will not reduce sear engagement/creep, but just mask it. One must be careful to not take to much away, so that when the bolt is cocked, and the safety is moved to fire, that it fires without pulling the trigger, when the safety is moved to the off posistion. Like I have said, this is surgery for someone who has experience.
