FX make 2 semi-automatics. Semi -auto's are illegal in this country but not abroad nor elsewhere.
They are called the Revolution and the Monsoon, both have had teething troubles but generally are awesome rifles.

If you go to their website and watch the Download section there are 2 clips, The FX Challenge and the semi-auto show.

Both totally awesome vids.

If it was my choice i would have the Monsoon with a bipod and a NV rig in a.177 FAC flavour. Then i would just site myself around my busiest warren about 50m out with a slight breeze in my face and just wait for the crowd to appear.


But thats just me!!
