Selling my VFC mk18 with prowin and prommy tbb. Currently have the mancraft pdik all mechanical hpa engine installed and have drilled and tapped the gearbox for the perfect alignment. With a suppressor people cant hear you from 10ft away... it's pretty amazing. I'm only really interested in krytac but I'll look at any m4 with a btc mosfet. Ftf preferred but willing to ship.
