Hey Guys,

I was at my local gun shop yesterday and saw a GSG-5SD on the wall..... long story short.... it came home with me! Neat little rifle! I am not sure why I wanted it.....
I just did!  

I have a .22 can that I would like to use in this rifle... but I do like the way she looks with the fake  SD can... If I was to do the SBR route with her,
I would like to mill out the front of the fake can and thread  my real suppressor inside the fake can.... Has anyone done this.... I think I read that it was done... or
eluded to... but I am not sure. Is there any reason not to? If so any pics?

Thanks !

This Thread Is Useless Without Pictures!!!

J/k pics would be nice. But congrats on your new purchase. I love my GSG 5 and I think you will too.

WOW I want one now.  The standard one looks lame, but the SD looking one is very cool.

Hey Guys,

O.K... I'll try to get a few pics tomorrow.... I just did a detail strip.... interesting piece! Looks like it is going to be fun to work on! Next I will try a light trigger job!
I am not sure if I like the titanium finish.... I am thinking black duracoat would be more my cup 'o tea!

If I should I go the SBR route I noticed that the barrel is too skinny for a 1/2 x 28 thread job, so I need to get a replacement ATI  barrel , have it cut to 10 7/8" (Give or take!)
and have the barrel end threaded, and an adapter made to "step up" the barrel to my Suppressor's 1/2 x 28.......

Does anyone make an step up adapter ? And If so what thread pitch would be best for the barrel... Something pretty  fine I bet.....

Any thoughts???

Thanks!
Fred

P.S. one more screwy thought....if the fake supressor was perminately mounted in place, giving the " overall  length" of 16"  would not a SBR be uncessary........ no matter what the "internal" barrel length was.........
 
                                                                                             
                                                                                                  (I bet that won't fly....but it is worth a try!)

I have one of these also.

As for shortening the barrel in the shroud to attach a suppressor to, first you would need to take the fake can off to access the barrel.  Next, the fake can would have to be permanently attached to prevent the need for SBR stamp.  The problem you have now is that even the "shroud" or fake cancould be considered a real can now,  This holds true even if you mill off the end of the fake can to slip the real can into it.  The next problem is tightening and loosening the real can with the fake can on the barrel.

Your next best option is to have a can permanently attached.

Or cut the end off of the fake can and form 1 it and put your own guts in it and permanently attach it.

Hey Wes,

Yeah, it does sound like a bit of a  messy one....from a legal standpoint........You would think that as long as the "Barrel Assembly" is at least 16" long it should not be an issue.... but I have a feeling ATF will say it is a Barrel that must be 16" long, not a barrel assembly.  I may call up ATF and ask them for an opinion.... that might be interesting..... How would this really be any different fron a 14" AR barreled upper with a muzzle brake/flash hider permanently attached to make it a legal 16"?

From a logistics standpoint it sounds easy enough.... the toughest part would be the drilling/milling of the aluminum  endcap of the fake suppressor to the 1" diameter of my real can.....
(A Tac 65 rebuilt by Elite Iron...),  if the real can should somehow get stuck........ it is easy enough to remove the barrel.... push the whole assembly through the fake can, (even if it is permanently attached to the front sight base),  and fuss with it clear of the fake can.......

I would imagine that if I did this and wanted to shoot it without my suppressor attached, I would have to install a 1" diameter fake can into the SD fake can, to keep from messing up the larger fake can.... I'm not really  so worried about pressure....... as much as the mess!

What does everyone think..... Will ATF Go or No-Go  this project.... It does sound like a cool idea... I am just not sure if it is worth all the form 1 hoop jumping.... (That and I have a Krinkov to build up and form 1 !)

Thanks

I would imagine that if I did this and wanted to shoot it without my suppressor attached, I would have to install a 1" diameter fake can into the SD fake can, to keep from messing up the larger fake can....

I think your best bet is to buy a dedicated suppressor for this weapon that either fits in the fake can and permanently attach it or sbr the rifle.

Hey Wes,

I asked this question On Uzitalk, and the general consensus is that so long as the fake can is permenately attached and over 16" in length it would be good to go.....
I think I will call ATF's Tech Branch and see what they have to say.... It may be an issue if the fake can is threaded into the front sight/cocking tube, which is in itself
"readily removable" from the receiver of the GSG-5....unlike on the MP-5, Cetme, HK94, Ect

I may be dreaming but it would be nice to do this without having to go through all the headache of a Form 1.....

If this works and ATF gives it's blessing.... does anyone know who makes a step up adapter from the barrel size to 1/2 x 28? The barrel is too skinny to thread to 1/2 x 28....
it actually fits inside the threaded end of my suppressor.... so that is a bit of a problem!

Thanks!

That is correct,

As long as the fake suppressor body is attached to the BARREL permanently (Pinned, welded, high temp silver solder) it is considered an extension to the barrel just like a flash hider would be.

For example Tactical Solutions 10/22 barrels:



Wes is mistaken about the fake can being considered a suppressor. If the device does not depress the db level, it is not a suppressor and a hollow open ended tube is not going to suppress db.

No different than a golf ball launcher or a KX3 with or without it's cone.

All I have been saying is that the barrel and anything attached to it must be of a minimal length of 16".  If the barrel itself is less than 16" and does have attachments, those attachments must permanently attached to the barrel.  If you are planning to attach the fake can to the barrel after the barrel is cut down the end of the fake can will need to be opened up so that the diameter of the exit hole is the same as the ID of the tube.  Any reduction of the exit hole from the ID of the can "could" result in redirection of gasses and a "potential" sound reducton.  Just remember that the fake can, tube, etc. must be permanently attached the BARREL and not to the receiver if the barrel is less than 16" and thaose attachments must bring the barrel length to at least 16".

Hey Guys!

Thanks for the advice.... I think I have it now.... just blind pining the threaded section of the fake suppressor to the threaded front sight/cocking tube
likely won't cut it, because the barrel would have "free travel" within the front sight mount.... the barrel, the fake suppressor, and the front sight mount
all must be permenately attached to each other, hence one unit,  to make ATF happy! I only include the front sight mount, because that is the easyest place
to attach the fake suppressor to the barrel.

And point taken about the fake suppressor, maybe drilling vent holes in the muzzle end would help to show my good intentions of not trying to make an
illegal suppressor out of it.

I do believe..... I have it now!

Thanks!

Jerad:  You can take the KX3 off you list as a device that does not reduce db levels at all.  It is pretty amaizing that Noveske was able to get the ATF to classify the KX3 as a flash hider when (from all the tests I have read) does in fact lower the db level 2 to 5 db depending on barrel length.  The inner removable cone really acts like a one cone baffle.
