This is a feeler as I am not sure if I am ready to let this go but this hobby makes you want to try and test new things. This is a Ernest Owned gun that I bought from him it's a mk2 that has been upgraded to some of the m3 items like the 720 plenum, acorn valve knob all installed by him. I put the trs rail and the Saber Gen 2 arca rail on. It's a .30 700mm and 580cc bottle with a new superior liner Ernest dual transfer port carbon liner sleeve, fx barrel clamp and tensioner not installed it can include. Will come with 2 mags one with an orion insert. I also have a slug A and a superior heavy liner available pick and choose are take them all if we can work out a deal. This is a 100-120FPE gun. Any questions just ask. What am I looking for honestly I don't know uragan, cricket tactical, no electric triggers but open to see whats out there let me know what you have.
