i have a basically stock tokyo marui hi capa 4.3 with a mag adapter. all that’s basically upgraded is it is perfectly short stroked to have an insane trigger response and very snappy shooting. It has been very lightly used and cleaned after every use. no parts show any signs of wear. i love this thing so much but i need money for my new build. message me for more pics are any videos and i will be happy to send them.
