Older style hpa system Full auto and safety selector 3 mags, 1 m16 style, 2 ar15 style Only issues are that the rear sight is missing and that one of the mags needs a check ball to keep the bbs in the mag I have not tested this gun as I don't have the right connector for these older style hpa ends Folding stock Has a recoil feature similar to gbb rifles Taking offers or possible trades
