The Box Gun

About: I love Knex.

Look at my Panther Pistol

This gun has a great new concept. The connector (In this case happens to be an orange) goes down the barrel in the connector's middle hole, and you pull it back, let it go, and it slings it. It shoots about 40 ft. This gun does not have a trigger, feel free to comment for trigger ideas. Please comment and rate.

    i had an idea like this a few years ago, but it was actually a ram and it fired huge blocks of knex. the only problem was the trigger. that and the fact that it kept denting my wall.
