No, I hadn't concidered that, it might be the way to go as it doesn't need to be as stiff as the original as it will be supported by the trigger housing. I was thinking about taking two pieces of angle iron and welding a spacer in the middle to get the gap for the mag release. Its going to get welded to the front of the 1-3/4"x1" square trigger housing so it doesn't need the raised edges on the original to retain the stock.
I was thinking about the remington setup more for the suomi set up where the trigger has to be set back from the hammer. As you noted the hammer might need a little more mass as the 1100ect firing pins are lighter than a ar15 pin. Although the firing pin head is smaller on the remingtons and they seem just fine with the side to side play. It still looks like it would be a good choice though.
Chief, now you got me thinking. The 742,7400,7600 hammers are shaped a little different and look like they have more mass in them for the harder rifle primers.
Somebody out there who isn't using the original trigger pack (and maybe other unused small parts) for this project want to donate one for a dummy Suomi project?
I thought I'd repost the pics of the barrel bushing I'm using since they were lost with the upgrade. I made the barrel bushing long enough that it will go back to the step up in the bolt. This will be similar to the way a suomi receiver is and will limit where an empty case can jam in the action. When I get around to making a semi suomi I'll make a barrel like this one and cut the barrel jacket lugs into it. I plan on attaching the ejector to the bottem left side of the mag well opening in the barrel bushining. Other than that I made a barrel extension and threaded the barrel for 5/8"-18tpi. I have the magwell opening almost done and will get a pic of it up when I finish it.
anybody have some left over suomi parts they would 'part' with at a cheep price? I'm not asking for a barrel, specifically interested in the trigger group, going to disable it for a dummy gun so rough or missing the internals is probably okay too....anybody?
I'm going to be using my trigger group for a striker fired suomi build. Sorry I can't help.
Anybody else want to part with some small parts? Trigger pack?
could sombody please post what size tube for the reciver was used on the SGN9. I did not get that issue and do not know what tubing to order. thanks
