I did the 15 minute trigger job last night and tried it out today. I don't have a trigger pull gauge but I could tell a substantial difference and my groups were much better. EM 4 Doublestar carbine w/ 16" chromelined barrel and Nikon 3x9x40 scope at just a little over 1" 5 round groups at 100 yards. All rounds fired perfectly w/ no problems what so ever. I use it for a coyote rifle and I usually call'em in fairly close and don't shoot anything more than 200 yards and most of the time much closer than that so it's pretty well set now for my needs. The trigger broke fairly clean before the trigger job but the pull was just plain heavy. Now it's much lighter and break clean as a whistle. Thank you Sniper for the link. You saved me a $120.00 that I was about to spend on a 2 stage NM trigger. I'm going to go calling in the New Mexico desert tomorrow. I'm really liking this little rifle now.
