I have one for the Scorpion. I am underwhelmed enough that I probably wouldn't buy one for another platform. It's fun, and it's slightly better than the CZ's stock trigger, but it still isn't a auto subgun.

I haven't checked too much on the MPX version (which is the AR version?), but the Scorpion version does suffer from some malfunctions (based on online chatter) and has a spring that wears out quickly causing it to just be a semi again. I do know that any thoughts I had of getting one for a full size rifle or an AR pistol are gone.

I have a friend that has one in his AR-15 and he loves it. I shot it the last time I was at his place and it was a lot of fun. He hasn't had any issues with is that he's mentioned. After shooting his, I am going to get one for my AR-9.

they seem to work in everything but the mpx. it wouldnt work on semi in mine but it did run on binary. i dropped it in my colt lower and it does work great with my cmmg 9mm upper and cmmg drop in 22 conversion.

I just bought one, on general principle. Haven’t yet installed it, so no real comment.

I have a friend who has the Fos...(whatever it’s called - the “other” one). He seems to make it run nicely. I cannot. I have fired his a number of times and seem to stop the trigger press before the binary aspect engages. It then ends up resetting the second shot with the second pull (so doesn’t fire on the press). THAT is just weird! I have an auto-bolt but decided to try the Franklin just to see if it’s better/different. Comments elsewhere (on some survival/prep sites) seem to favour the Franklin because of not needing the auto-bolt.

I have one in my CMMG MKG45. The trigger feel is better than mil-spec. It very rarely malfunctions but the safety/selector switch requires a lot of force to manipulate. I usually lift my hand from the grip to move the safety.

It's the newer one purchased a few weeks back.

Called today; the Franklin website phone #.

Thay said; "since the MPX, is not MIL SPEC, we give it a 50% chance on it working"

so basically, theydont want any responsability on the matter if it DOESENT work..

50/50? hmmmm... i get it, the dont want returns or hassles...

But , does it really not work?

I had the Franklin Armory Binary when they first came out in 2 different AR15’s. They both ran good but they were not in a **** rifle. Just my experience.

If the manufacturer does not stand behind a trigger for the MPX, it likely means they have no confidence that it will last in an MPX. The fact is that the MPX destroys trggers due to high bolt speed under recoil.

But....the MPX bolt can be slowed down by heavier recoil springs and/or a an adjustable gas plug. The adjustable gas plug usually works best with the port opened up. ILWT is the source of this gear. I use their heavier recoil springs. Service is usually fast and reliable.
