ShinSung Career II 707 Moderator Adapter

I bought an m10x1 to 1/2-20 adapter from DFL, but the body of the adapter is too short and the space between the shroud & the tube is too little to let any of my moderator screw all the way down. Found a 3D printed 1/2-20 Male to 1/2-20 Female, printed it, and it is too wide for the channel between the tube & the shroud. Broke out Mr. Dremel, narrowed it down and wasn't happy with the result. Found a male-female on BestFittings.com (Brit) and paid through the teeth in shipping but it *should* work. 16mm which is the correct diameter.

Any other options out there? M10x1 to 1/2-20 is the required adapter.

Thanks,
Matt
 
The fill cover is about 1mm from the barrel end cap (16mm diameter). That unscrews and there are M10x1 threads on the barrel. The m10x1 to 1/2-20 Adapter screws on and you *should* be able to attach a moderator. However the adapter is too short and the moderator hits the fill cover.

Even with the foster fitting on my 707 2 .22 most mods will not fit. I have 1 that will and I think it was an Alan Zasdny mod. You can see in images that it has a threaded extended neck to screw onto barrel. I received it with the rifle and have no idea where to find one. Maybe someone on here can help you locate one. Hope this helps

Where did you get the foster fitting?

It looks to me that the m10x1 to 1/2-20 adapter you need is one designed to fit the Seneca Sumatra.
The nipple is long enough to get the 1/2-20 threads far enough out in front of the tube to screw on a moderator
If I were looking for one, I'd try AIr Venturi, (the Seneca importer) and would also do an eBay search for Seneca Sumatra.
Come to think of it DonnyFl probably makes one

You may even find a complete moderator for the Sumatra, built with long nipple, to go directly to the M10x1 barrel end
Also, If Neil Clague is still in business, he specialized in those moderators

That is the adapter i bought.
it is too short. needs about another 1/2 inch to clear the fill cover.
