Seems like just about everywhere is outta stock. Thats a good indicator that Mega hasnt made any recently.

For Single Stage, the ACT trigger is Sweet, if you insist on lightening the pull some more, some reduced power JP springs will give you an extremely light, crisp trigger for less than $80 for the pair.

The only reason I wouldnt use the JP reduced power springs is if you shoot a lot of 5.56 surplus.. supposedly they have hard primers and once in a while a round may not fire. I would think .223 is no problem with those springs.

My ACT has the stock springs and the pull feels like 3 or 4 pounds. I should have it measured next chance I get. It feels terrific.

ACT with stock springs is great. I might do a rifle with the low power springs, but 95% of my centerfire ammo comes out of a Dillon.

Its not the pull I'm concerned with. It feels like a smith and Wesson sv40. The second sigma. Just gritty.

If you have a chance to break it down take the trigger and sear out and send it to me and I'll do a stoning on it and that grittiness will go away. I don't advise anyone doing this at home unless you have the training and jigs to do this job and end up with a safe trigger after you install it. Shoot me a PM and I'll give you the address.

The problem with doing trigger jobs on milspec parts is only the outer surface of the parts are hardened. Once that surface is removed, the softer metal is exposed. Trigger may last a long time or only a couple hundred rounds.
I have been using the JP trigger group for years and couldn't ask for more. That being said, the Hyper-Touch "C" trigger is slated for my next build.

I have done hundreds of "Smooth &Tune jobs" on AR's. The only time you run into cutting thru the case hardening is when you take too much off. The trigger and sear have a flat surface that has burs on it. You don't touch the "flat" surface you only address the burs. This is accomplished with a 4000 grit stone, a jig, and a 15x microscope. If you have the training and the proper tools it is easily accomplished. You can't cut length of pull or applied weight by doing this. Only smoothing the trigger pull and perceived weight should be adjusted. If you want any thing else out of your trigger you'll need to get a specific application trigger (Geissele, Timney, or a whole host of other manufacturers).

Not doubting that you do a fine job. The OP was asking about "diy" triggers. The average kitchen table smith doesn't have the stone, jig, 15x scope, or know-how. It's very easy to ruin parts.

I agree that's why I wanted to clarified what it takes to do a safe and quality trigger job on mill spec parts.

And yes I got the point. Im not touching it. Gona ship it to a Gunsmith and have it polished.

I still do many of my own. Never a problem

I've got a Geissele SSA-E on the way. I can't wait to get it out on the range in a few weeks.

I installed it on Wed night and ran it at the range on Thursday. All I can say is wow, I am really impressed and very happy with this trigger. It could be a little bit lighter on the second stage, hopefully it will wear in a little and lighten up.
