Thanks for the heads up. I emailed LaRue this morning about MPX compatibility, received the following reply: "We do not recommend our trigger to be used in a 9mm rifle/pistol from any manufacturer." Looks like my search for a decent trigger for the MPX continues...

Meh. For $87 right now I'd be willing to try an MBT in an MPX, and if it didn't work simply use it in one of my other ARs. Meanwhile, Timney's MPX trigger is getting good reviews. I'd still be tempted to try the MBT first just for the cost savings though.

ETA: since I'm seriously considering an MPX for a "truck gun", I've been doing some reading on the purpose of the trigger bridge - bolt velocity on the MPX seems to throw the hammer back a lot harder than on a standard AR, resulting in the disconnector getting beaten up by the hammer and eventually causing problems, so Sig came up with the bridge to prevent the disconnector from being abused. The rear top surface of the Sig disconnect is lower than the rear top of a standard disconnector, so it might require some judicious filing to shave down a regular AR disconnector to match the Sig OEM disconnector specs. I'd probably experiment with that on a standard AR trigger group first & see how it worked, and if successful then I'd carefully work on the MBT disconnector if necessary.

(I don't have my MPX yet, so this is all in theory for right now. I'm loving the MBT in my other ARs though, so I'm hopeful this can be made to work).

The trigger bridge on mine is definitely getting some love from the hammer during cycling. The HK416/417 also use a trigger bridge and for the same purpose. The bridge does it's job well, so i see no reason to remove it and/or monkey with standard AR trigger groups that would be no better than the factory Sig trigger. I'd rather deal with a shitty trigger than one that goes rouge one me. As for the MBT, i'm 100% certain it would work in the MPX. I'm just not sure for how long.

Just for clarification, I was trying to say that Sig is using the trigger bridge to stop the disconnect from taking a beating. I didn't mean to imply that Sig came up with the trigger bridge idea, as rereading my post seems to imply. I've never used a 416 or 417 - I had a POF piston rifle in 5.56 about 8 years ago that didn't have a trigger bridge. I wonder if HK's piston system is different enough that the bolt velocity is greater, or if they're just being cautious?

Anyway, I agree that the MBT would work just fine (in the short term) in the MPX. My first hand experience with the MPX is limited to a sample size of one (my buddy's gun), and while I liked almost everything about it, the trigger on that was comparable to a low-end budget AR home build. Meaning it sucked. Once my MPX is in hand I'm going to do some experimentation with an ALG ACT disconnector (since that's cheap to replace) and if successful I'll look into modifying a G2S or an MBT disconnector. Either one of those (or even the ACT) should be a vast improvement over the stock MPX trigger.

HK being HK, it's probably typical German over-engineering. As for modifying disconnectors, if your goal is to get the Sig trigger bridge to fit and work with triggers other than the stock MPX trigger, you'll likely need to modify hammers as well, as the shape of the MPX trigger is unique, allowing it to both be stopped by the bridge and allow the bolt to cycle properly. Other triggers may bottom out on the bridge and prevent the bolt from cycling, or not stop the hammer soon enough and still pummel the disconnector. But i reckon this is a technical discussion, and subject for a thread other than this one.

O.K., guess I worked a good, sweating, damned near falling to my knees, dizziness hard core kind of guy, so if you'll sell me that Colt Python, I think you'll be able to make us whole again.

I tried, but for some reason you have to live in a handful of states. MN is not one.
