Built by a pro, and can hit 4 joules with a 200 PSI regulator!!! I have hit targets at nearly 400 feet with .48 gram BBs!!! With the HPA setup the FPS is fully adjustable. Everything works like new. Serious inquiries only please. What you see is what you get including 1 mag. More pictures, and shooting videos available upon request. Shipping not included in price. Currently only looking for Wolverine HPA units or complete Wolverine HPA guns. Local trades preferred (34614, Central Florida). Long distance trades can be done, but you ship first and I will send trade once received and inspected. I have quite a few listings, check out my profile to view them all.
