This is the knex version of the M41-A from the movie, "Aliens". IT has a 5 shot mag. a ram rod puller that comes off the side and many other features. Please note this is my first ever BIG gun build so its not the best. Range is about 25 feet +, but if you add more bands it could go farther. This was requested by Hedgehog0 and he will be working on a grenade launcher attachment for this shortly after I post the instructable. Thank you for looking and please comment and rate.
