Shin Sung 9mm

[PellMaster]

I picked up a Shin Sung Fire 202 9mm rifle this past weekend. I would like to put a moderator on it ,but I don't know what adapter to use. The barrel is threaded, I found 1 nut at the local hardware that fits the threads, but it obviously was out of place and is an oddball size. The threaded barrel measures .45 inches in diameter. If anyone knows what size or where to get an adapter I would appreciate it. I will post some pics shortly.

It could be one of two threads:

The best way to tell is use a dial caliper and thread pitch gauge. You can also bring it into a machine shop and they will measure for you.
Don't bring in the endcap only for measurement! Tolerances are too loose for an accurate reading.

I appreciate the advise. I contacted DonnyFL, but they were no help. I found a nut that threaded on the barrel, but it took a lot of looking. It wound up being an M12 x 1.00 thread. Apparently it is an unusual thread pitch for M12. I wish I had the end cap,it is missing, that is what prompted the search in the first place.

I've been down this road before. You are correct regarding Donny. They'll move heaven and earth to identify the M12x1 thread is for a firearm to not make one. Make absolutely sure with a thread pitch gauge and dial caliper. Then get Neil clague to make you an LDC for direct attach. You will also need to measure the distance between the tube and thread. He doesn't make adapters or accept returns. Of course it is ideal to make a M12x1 -> 5/8x18 for cost savings and compatibility, but I don't know of anyone who makes them to order without charging $200.

Neil Clague Shrouds and LDC's

The LDCs are first rate. I can assure you of that.

I have a friend that is a retired airline machinist. He has made a few things for me before, as you can see from the pics I need to extend the barrel out past the fill port before putting a moderator on it.
