So Geissele had an MCX trigger but no MPX trigger for a while, and finally came out the the MPX trigger, just in time for their black friday 30% off sale. I bought both and finally got them today (conditions of the discount are waiting up to 8 weeks).
I can definitely say, at this price (like $100 off on each) they are worth it. Both are 2-stage about 4.5 lbs total. The break is a little less crisp than Geissle AR 2-stage triggers, but much better than a standard MPX mil trigger and the match-duo trigger in the Rattler.
The Geissele MCX and MPX triggers are essentially the same, both with the sheet metal bridge that backstops the hammer on recoil. The only different I can see is the disconnector on the MCX is blued tool steel while on the MPX it is coated in a silver friction reducing plating.
Not sure if the replacement higher power recoil springs on the MPX trigger are really needed, but Geissele says they reduce bolt speed and help prevent hammer failure. I may experiment with them, but I want something that can shoot any ammo, including weak WWB 115 grain.

Hmm …. That’s what I get for ignoring Geissele’s nonstop emails advertising their discounts and that showed up every hour or so before Christmas. I didn’t know they offered a trigger for the MCX. Will have to consider it nevertheless.

They’ve had their MCX trigger out for a couple of years. Their MPX trigger is relatively new. I picked up one a few months ago, during one of their sales, which seem to happen about every major holiday. To be honest, I don’t think the new trigger is better than the two stage Timney AR-9 trigger that I had in my MPX before.

I'm not sure what timney you had in there. but the original one I had in my mpx (681 as originally recommended by Timney) didn't survive. I later got a 683 and hate it. I haven't seen my MPX geissle from the black friday sale, but I'm hoping its way better than than the Timney one. we shall see...

I am running Hiperfire triggers in my two MPX's. I have had them in a couple of years and they seem to be holding up just fine. I have a little under 2000 rounds through each of them.
I ordered 2 MCX and 1 MPX trigger on Black Friday. Still don't have them yet. If they are as good as my 9 other Geissele triggers, they will be worth the wait.

I was thinking about a Timney trigger upgrade, could you please expand on why the 681 didn't survive and why you hate your 683?
Regards
