Got roped into this..no one was making barrels..so yeah.. it's expensive an there's a list but first barrel is ready so time to come up with a semi design. We have the only to spec an print barrel on the market. Here's some progress.
Fluted jig was fun..each rib is a different dimension an degree of timing.

Damn it, I did not need to see this. I’ve been eying the kits for sale telling myself I don’t need one.

Well I'm sitting here looking at the parts.. thinking.. looking like striker fired should be fine, will need dual springs. Now the question of big round striker hitting firing pin..or big firing pin with a sear inside a milled bolt..hmm

Great. Now I just learned about another gun that I need.

Needs more filler, more clean up. Etc but progress has been made. I believe I can make a striker that rides inside the bolt an avoids the center placed ejector.

Now you need the French cravat!

This is such a great project! Never even seen a pm12 in person.

Now the real fun... These have a semi selection..but gotta make it so you can't play swap a hoe with parts an make a mg again.. denials and mods of this overly complicated fcg is gonna be fun. I already got several ideas but will have to mock it up an test everything.
