Getting deeper into finishing an RO727 clone (yes, I know its A2), but I spend literally all my time here in the retro forum and my fellow retro heads are just an endless wealth of information. That being said, I'd like to do my 727 like in the below posted pic, which is fitted with an OPS inc 3rd model suppressor (i think). My question is does / has anyone made a FAUX OPS inc can or have the can's actual dimensions.? Building a fake can is possible as I have a lathe and bridgeport milling machine at home and I'm in need of a new project. Any help or comments from you gentleman is greatly appreciated.




 

I've inquired before and never found anything satisfactory.  I'm very interested if anyone has or makes one.  
Worst case, I've got an airsoft version I can measure for outer dimensions.

Yeah, I think I've seen it before, but couldn't find the thread anymore. Whats the airsoft version made out of? Does it have the knurled gripping, markings, etc? I really don't want to spend the $ on a real one, thus, the idea for a fake slip over.

 

I'm sure it's aluminum.  Nothing I'd want to put on my actual gun.  But yes, it's got the knurling, and markings of some sort (can't remember if they're correct or not).

I'm in the process of making a fake can for my rifle.





Maybe we can share what we learn

ETA:
Looks like maybe all you need to do is by the King Arms Ops Airsoft Can



Maybe it won't take many mods to get it to work. Looks like they have several models including the 3rd

If I keep this up I'm gonna become known as some kind of airsoft junkie lol. Actually don't own any airsoft rifles, but dang if some if the stuff hasn't become useful in retro builds.

 

It used a special locking mount.

Awesome e link and build with the KAC can! Maybe I'll buy the airsoft (gulp) version for reference and see what can be done. Thanks for posting that! Gives me hope Maybe I'll start looking at attachment methods in the meantime

 

So, I'm no machinist, but I've thought about how to make this before, while complying with laws about what is/isn't a suppressor.  I'm pretty sure I'd want something that could be disassembled to prove it's not venting anywhere.  I'd also want something I knew I could snug up on my barrel to be fairly secure.

None of this is modeled to any specific dimensions, but is just to show the pieces I was thinking about.

Red= Threads
Green = Gun Barrel
Blue = Barrel Extension.
Cyan = Rear Mount
Magenta = Sleeve
Purple = Cap

Originally I thought it would be useful to include a support flange on the barrel extension, but that may be moot given the rear support of the mount.  Either way, the intent would be that one could use a lock washer behind the barrel extension, and the extension would have wrench flats for tightening.  Same could be done for the cap.

That way, one could mount the extension to the barrel, ensure it's snug and not moving.  Then slip the sleeve over the barrel, install the cap, again snugging it down to the barrel extension, then slide the sleeve forward and screw it into place on the cap.  Finally the Rear Mount (which is actually two pieces held together with hex screws, I believe) can be put in place.

That is exactly what I did with my hel e4a I posted about above. Except I'm using a real .22 suppressor where you used a barrel extension, and I used a common rubber grommet for the end cap.

 


If I did not have the small suppressor to enclose I would have made one to slip over my A1 flashhider and mount to the rings on the back of the hider possibly using ball bearings for toolless removal.


 

woah! that is awesome CAD work! I'm gonna go ahead and buy the faux Ops Inc suppressor (full-size as that what it looks like in the pic I found). Too damn bad its coming from Asia, prolly will have to wait forever If were on the same page here (I hope we are) I agree with you on the possible need to machine some type of flange to go (perhaps midway?) down the tube to prevent wobble in the spaces between the tube and barrel.  I'll wait and see what I've got when it actually comes, at the very minimal I'll mock it up mounted with can for non-firing display purposes. Still its very cool what your guys have brainstormed already
