Lightening the markII trigger pull

I'm new to the site but I figured a way to lighten the trigger pull for non accu trigger markII's is very simple if u have the parts. All you have to do is replace the stock spring with a ar15 front sight detent spring. There are detailed videos on YouTube that show how to disassemble the rifle but all you have to do is cut the spring in half or you can cut a little at a time to tweak it personally I cut mine two loops longer than halfway if that makes sense and it works perfect. I also polished the sear and the contact points on the trigger and lubed them just a little. The springs are about the same size and you dnt have to alter anything that would void your warranty by drilling and if you choose you can swap back to your stock spring. I figured this would help somebody out there that wanted a quick fix for the heavy trigger let me know if I can help.
