View Full Version : Suppressing a PS90
March 7, 2011, 07:48 PM
I'm considering a suppressor for my PS90. The problem I see is that in addition to the suppressor stamp I don't see a way getting around an additional SBR stamp. The PS90 only makes the minimum dimensions, both barrel and overall, by the use of a pinned flash hider. If I take the flash hider off to mount a silencer I'm immediately in SBR territory. Does a pinned silencer get me around that, and would just the 2 min of SBR while I'm assembling it get me in legal issues?

Basically, there is very little way to do this without involving a gunsmith who works with NFA items. Yes, for those few minutes of having the FH off, if the barrel is still on there/able to fire, it's an SBR. Annoying, no? :barf:
In any case, it's worth getting the SBR stamp in addition to the silencer. It's a great little SBR, it cries out for you to do it. :D

Don't think you can find factory loads for a suppressor. You will have to get into reloading.

You could probably get a suppressor with a QD flash hider that will make the minimum length, and have that pinned on.

I'm not looking into a "silent assassin" type suppression that requires subsonic rounds (so I'm into reloading) just something that can be fired indoors without leaving everyone's ears ringing. But we seem to all agree it's a $400 for the 10" barrel +$500 for the suppressor +2 x $200 for the stamps project to be done right. What, with a $1500 gun, makes it a serious investment thing.

If the barrel comes out of the P90, then they can cut it down, crown it, thread it, and weld a suppressor on the gun, if that's really what you want to do.
However, it's worth having the two stamps. Best kind of stamp collecting, if you ask me. ;)
Also look into a "one suppressor fit's most" kind of setup. The Liberty Mystic, for example, is a 9mm can that is user serviceable, and can be used with .22, 9mm, .223 for limited use. You can find it on THIS PAGE (http://www.libertycans.net/mystic.html).
They don't list the 5.7 specifically, but I think if you talk with them, you'll find it will do fine on the 5.7.
