PSG-1 Silencer Adapter
 

G'day,

I have a PSG-1 silencer adaptor that doesn't have threads on the exterior, just threads to connect to the barrel. What sort of supressor does this thing adapt to? I didn't find any PSG-1 specific supressors and of course there's no docs with the rifle.

As far as I know PDI is the only company that makes the adapter for the PSG-1 but it has 14mm CW threads. Check out Redwolfairsoft.com and see how it compares to the one you have. The only other possible solution is to find a silencer that attaches with hex screw.

sounds like the old type of set screw silencers...

Before japan realised threading was a good idea.
