ANM2 semi build concept

So far, I've not seen a 30 cal ANM2 semi build. Biggest issue is there simply is not enough room to install a semi disconnector like used on the 1919. Sear also trips by pushing UP not pulling down like on the 1919.

I've spent better part of a month learning Fusion 360...

Then I modeled an SA lockframe for the ANM2. This may be clear as mud to everybody else. The idea here is the yellow block can hinge forward 0.125" to act as a disconnector. The SA trigger bar (red) has a square catch that will hit the sear if the trigger is pulled. Not shown, the SA sear will need a matching square catch.

I was going to model all the parts, but I am just too damned slow at modeling. got enough done to machine the parts I will need. We will see, but the parts should fit right the first time. I am leaving an extra 20 thou on the trigger bar in a couple spots for final tweaking. Same with exact location of the green stop block.

The first pic shows the existing FA lockframe. Next pics are of model. Second pic has one of the plates removed for better visibility.

so far, this is just ideas. Not sure when it will get built. Also, if somebody else has a better concept, I'd love to try to model it.

Always good to see ideas out there for this. There have been one-off semis done. I had pics of one years ago, but while I could see the denial island design, the pic I had left the trigger/sear design to the imagination. There are a handful of us with kits, and based on that the market is small. But you never know when things might change on that front. Keep us up to date, Karl, and I am also putting some thought into this.
