    it a good design
    but, i missed out 2 small blue bits and when its under 16 bands on power it just blew up when i shot it ;(

    No, this gun almost never blocks and the mag doesnt block either !
    the only problem you can have is that the pushpin falls apart if you use to much rubber bands but you can shoot very fast without blocking :p

    yeah, thats a problem you can have with every gun :p just use less rubber bands or add duct tape to the fireing pin to hold the peaces in place


    Reply 7 years ago on Introduction

    yeah indeed ! if you dont use any ammo your fireing pin wont be slown down and will deconnect.
