1. Milspec has little to do with it. All my AR's minus one have a "mil-spec" trigger. 1 Bushy, 1 RRA, one Olympic, one Colt.
Two SUCK, two are SWEET. Luck of the draw, my friend. It has to do with the grinding job on the surfaces, the strength of the hammer spring, and luck.
2. You CAN do something about it. A good flat sharpening stone, and stone the surfaces on the trigger bar. Go easy! This will take out the gritty-ness, and smooth them up. I have done this to two of mine, and it has helped tremendously. I have been using CLP as a lube, but many others have recommended NECO MolySlide on engagement surfaces. I am going to try this soon.
3. I went with a Rock River 2 stage on my Varmint rig. GAWD is it SWEET! No gunsmith needed, no adjustments. Just pop it in (5 minutes) and go. For anyone wanting a do-it-yourself no nonsense simple upgrade for dummies, I HIGHLY recommend this trigger. Oh, did I mention it's only $85 from
www.sableco.netPersonally, I like the heavier triggers on my non-competition M4 type rifles. I feel they are safer, and do the job just fine. I just touch them up a little.
Your AR must be exceptionally bad, because the AK47, (yes, every single one I have ever shot on MANY rifles) just absolutely SUCK. There is no "break" Just more of a single stage of nothing but creep, until the hammer "slips" off the trigger bar. I'll take a default AR trigger any day.
