Luger with threaded barrel

The thread size may be 1/2 x 28tpi...The same as an AR-15/M16 flash hider. Many suppressors are threaded this size. If you have an AR, try the flash hider on it.

You can also look through your bolt can and see if you have a bolt with that pitch [1/4" UNF 'fine' thread is 28tpi] and then just measure the diameter of the threaded portion of the barrel...If it is .496" [just under 1/2"] then it is a 1/2" thread...

There was a guy on eBay (or was it GB?) selling threaded Luger barrels a couple months back...
