Threaded outer barrel for hicapa

[KBoy76]

I’m struggling to find a threaded outer barrel for my Army Armament Jag Precision x Taran Tactical Combat Master, so I can run a tracer on it. A helpful guy on here recommended getting a 5.4 r601 outer barrel which has the threading. However I can’t find one of these in stock anywhere, so wanted to ask if anyone else knows of other alternatives?

Any advice would be greatly appreciated.

Thanks in advance
