Selling my HPA Evo with a Wolverine Gen2. Comes with an Orga Lex barrel, prommy purple bucking, maple leaf flat hop nub, 6 mid caps & one high cap. Selling due to fund a new project. The empty mag detection doesn’t seem to work due to possible trigger board problem but never bothered me as i just took the mag detection lever out of the mid caps. Can sell with orginal barrel and hop setup if preferd.
