Well it is almost impossible for SSD to export parts outside EU so that s why they dont sell parts to USA.
Childers, copes and other are not importing flats, they are importing 80% bent blanks from Poland, these have no rails, the flats folk use are made here in the US
I think the interest is there. But from alot of comments I've read in the past, alot of guys dont want to pay $5k for a repro semi only MP44 clone. If there were a semi only receiver available who really knows how many parts sets are stashed away in closets that will either get sold for alot more than it was originally priced at. Or how many would be built into working semi's. To bad SSD or whatever they call themselves these days dont sell just parts stateside. Without a source for parts, affordable reliable parts, it might be hard to sell just a receiver.
I think I'd have to disagree re demand for receivers. Many guys that want to build up a 44 might very well have a parts set. My thinking is that the lack of a receiver or enough left of a destroyed one for one to rework is the reason for parts sets that are not built. I don't know that much of anyone is thinking they'd be wanting to buy a bunch of PTR parts to build on a US rec. I'm not brainstorming complete rec. in any event, just the sheetmetal shell to go with the rec. blocks soon coming.
The big question is that since the tooling to stamp out that shell is so costly, not having any way of knowing whether enough would sell to justify the cost makes it worthy of much hesitation. I suppose one could collect healthy deposits until enough were gotten to justify starting the tooling. NOT,NOT, NOT, all of us who have been around the gun world a while know how those kind of deals have gone with years of delays, unkept timelines, lost money, PO'd depositers etc.

I dont really follow what you are in disagreement with regards to my post. I reread it a few times and dont see where what you wrote disagrees with where I was going.
