Can't seem to figure this one out.  Every since I replaced my M11 internals with some of the Lage lower parts, my gun is no longer select-fire.  Full-auto only.  That being said, the issue is more likely the user (me) as these guns (I have two.  More on that later) and they are both doing the same thing.

M11/9 #1 -  Ran 100% when I replaced the almost all of the lower parts with the Lage lower internals.  When I got M11/9 #2, I decided to upgrade the trigger to the select-fire Lage trigger.  I don't know what I did, but now there no tension on the improved trip.  It just floats there.

M11/9 #2 - This is where the issue lies.  When this one transferred, I decided to upgrade all the internals with the Lage stuff as well.  I wish I didn't, as I have no reference with a stock gun to compare it to.

I took a picture of the internals before the good-idea tools came out.  I cannot seem to pinpoint what is going wrong.  These guns are simple-stupid like an AK-47, but I am loosing the battle.  I have tried to look up build videos on YouTube, both ones that talk about specific parts or others that show the complete restoration of a similar one (Mac 10).

So I've had it with myself.  I don't have the capacity (active-duty head injury) to scientifically troubleshoot this.  I have done what I am capable of thinking this through (visual-learner).  It just makes no sense to me that there is no tension on the trip.  The trigger(s) have tension and is 100% responsive when pulled.  Just no semi-auto.

Contact Richard. I believe he has a different disconnector for SA that is larger for cases like your. Some Macs are just looser or on the other end of the tolerance scale.

That will provide tension to a trip flopping around?

I have not had your issue, I still have the original PS FCG in my M10/45, but have read several people with SA issues in their Macs with the Lage FCG. All contacted Lage and got their issues sorted out quickly.

I think this topic came up on the uzitalk.com forum too.  I think Lage got them squared away.

It did but before it was posted here. The latest one I remember on Uzi I think was solves before this post too by Lage.



Would be cool to hear the outcome vs being ghosted like a one night stand.

Did you purchase the competition full auto only parts, by chance?
