Just got my evo3 s2 and I also want to do the hbi trigger spring job. What would be the best way to remove the trigger screw? My buddy suggested to use a soldering iron to heat up the screw, maybe loosens up Loctite a little? I even called hbi and they said use a good quality t handle Allen wrench. I’ll order the screw set also, for just in case. I’ll think I’ll end up stripping it. Thoughts? I’m confident on doing the install, I think the hardest part is removing that trigger screw.
A good T handle Allen wrench and be sure it's fully seated in the screw, did 2 weapons without a problem. Also be sure it is metric, some have not realized that and caused them problems. Yes order the screw set and replace the original. If your replacing the spring do yourself a favor and do the trigger also, saves taking it apart again. HIB offers some good choices, be sure to watch the video a couple time first.
