KWA VM4 ronin, in great condition with minimal wear. Has Ambi selector and stop on empty capability with the correct KWA mags. Gun comes with 1 K30/120 mag with extended follower and the stop on empty functionality. Wired to mini Tamiya, I find it I runs best on 11.1 lipos, although it has sat mostly unused, it was used in an event a few months ago but ran great with no issues. Known issues: Runs weird/ poorly on 7.4 lipos Wiring is kinda janky, it's how I bought it and it hasn't been an issue, but does look weird I am willing to rewire the connector to mini deans or xt60 on buyers request, and provide shooting videos.
