    Ok... how does the system work? the trigger isn't even in the pictures... I have no idea how anything works. (Great body though. p90 is my favorite gun)


    Im trying to make a p90 it has a removable mag that holds 30-35 rounds, it is in the same place as a real p90 but i dont know how to make the bullets fall into the chamber, any help here?

    I have an idea! leave an open piece at the end of the mag put a light rubber band on the gun then put another mag under it pointing down and shake shake shake!

    hmmm..............that might work, i will try that! exept i already destroyed it, im going to try to build it again!

    depends, is the mag going to be on the top or the bottom? if from the bottom, then try something that pushed the bullet into the mag. if at the top, then the bullet should fall into the mag. are you using tan clips for you mag?

    the problem is, is that its loaded in the same place as a real P90 so the bullets are pushed in straight up then they would have to drop into the chamber, i might use a mech similar to DJ Radios
