Hey Folks. 

I have here a JLS RX4. A Fairly rare beast. Difficult to get hold of. Used for one skirmish and is in great condition. 

The bits of the Outer barrel you cant see were shaved down for weight relief on a lathe. A very professional job. 

It sounds amazingly quiet, perfectly shimmed.

It is quite fussy with mags. It prefers standard Stanag Highcap M4 mags or Midcaps with low strength springs (Mid cap syndrome has always been a problem with these). I can include a midcap mag with it which feeds fine if half full. 

£210 picked up from my place in Central London. Postage will cost £15 extra. Priority will be given to those who can pick up first.
