Hand-held Shotgun ( V2.5 )

While attempting to make a bottom-fed magazine for v3 of my hh-gl series ( which seems impossible without making a shotgun) , I made two hand-held shotguns instead. While that may seem cool,my 10 year old (yes, 10 years) knex y connectors are breaking. Every other shot , one of my y connectors would break. :(


Ask for instructions at your own risk, this thing kills y connectors
