Barrel thread on my Virtus is 1/2x28. , Is this the same as 1/2 UNF? I am so confused on these suppressor sizes.
Virtus suppressor
- Thread starter Sublimemoon0000
- Start date
Yes it's for my Sig Sauer Virtus,, is it not 1/2x28? I watched a YouTube video from Airgun Detectives and they said it's 1/2x28.
Just curious, I'm still new to all this PCP stuff , I appreciate the help

1/2x28 is a firearm suppressor thread. You don't want to put one of those on an air rifle. If you did it would require a tax stamp from the "three letter agency" that can't be named.

Go to Donny FL & see their adapters. There might be one for your Sig.
I checked, here's the link:

I checked, here's the link:
SIG MCX VIRTUS 1/2X20 Adapter
Note: Remove the factory thread adapter and measure for the proper thread size. (If the thread size is smaller than 9.6 mm in diameter you will need the version 1.5 adapter) You have to remove the factory threads first. The factory thread has two flat sides where they can use a wrench to turn it...

From how I understand it I believe you have it backwards. A 1/2"x28 adapter in and of itself is not illegal. The possesion of the adapter in combination with a muzzle-threaded PB firearm can constitute intent to silence a firearm even if the silencer you possess is not intended or designed for a firearm.

My point was owning a suppressor with a 1/2x28 thread needs a tax stamp whether or not you have a gun to put it on. You could certainly argue intent, but I wouldn't advise it.
My comment was not about the adapter.
Apologies if my comment was confusing. Looking back I see I was not clear enough with pronouns.

OK, got it. Yeah, 1/2"x28 on even an "airgun use only" silencer is definitely a skiddly-don't.

Ok wait...so...the threads that are on it stock are 1/2"x28 , according to several websites. I have found a few mock suppressors with those threads, available for purchase between $40 and $100., Seems legal these are air gun websites I found them on. So your saying I have to have that adapter 1/2x20 , to make it "legal" ?

To own a 1/2"x28 threaded muzzle airgun: LEGAL
Possession of an airgun-use-only silencer with 1/2"x20 threads: LEGAL
Possession of a 1/2"x28" to 1/2"x20 adapter: LEGAL
All of the preceding are legal to own by themselves or in combination.
You risk AFT issues if in addition to the above legal items, you ALSO own a PB firearm with standard 1/2"x28 threads. In that case you now have the ability to install the otherwise legal airgun silencer on the firearm. Whether or not it holds up or grenades on your first shot is irrelevant. That is where you risk trouble because AFT could claim you had "constructive intent" to silence a firearm.

thank youSeems like getting the adapter and a 1/2x20 threaded mock suppressor is the way to go. The adapter is $30 and I can get many a different variety of mock suppressors, more so actually, for the 1/2x20 thread .
Thanks guys
Thanks guysUpvote 0
I don't see any problems with a Donny adapter and moderator as the 1/2x28 threads need to be removed 1st. (See link above).

If our airguns were threaded to accept silencers that fit powder burners, we would probably have to jump through the same hoops and pay the tax as if we were trying to be considerate to others by quieting down our .22lr's or other firearms.
As it is now, airgun silencers won't fit firearms and visa versa.
I think it was a smart move.

Not sure I’m following your logic. You think that the Virtus, using 1/2x28 TPI on an airgun was a smart move? Typical airguns threads are 1/2x20.
I think it’s weird that they would use the 1/2x28 threading that is common for powder burners.

I would have to agree , they should have made the threads 1/2x20 like all the other airguns. I dunno if they wanted extra "realism" ,or what the reason was, but those threads on the Virtus are very much 1/2x28. The gun arrived today and I put an old muzzle brake on it I had for a different gun, threads being 1/2x28. I think it was not a smart move on sigs part.
