Rubber Band Triggers - a notch above

Nearly all of the rubber band guns I have seen involve rather cheap plastic or wooden triggers, or even worse -- strange finger-twisting ways of releasing a rubber band to fly on it's erratic way...

Well, there are some exceptions to that, but let's settle by saying they are not "mainstream".

Back to mainstream, here is a more common example of a wooden and plastic repeater:

They may have an "ok" trigger pull, but it has several problems:

1. They are typically cheap, flexible plastic.  *
2. Pulling the trigger must rewind the whole spool slightly before release
3. This causes a much varying trigger pull, and
4. The trigger kicks your finger forward when pulled as the wheel rotates.

These problems would be totally unacceptable for a real firearm, which is not a toy.  It's time to make rubber band guns the same way, so the only "toy" thing about them is the fact that they shoot rubber.

* Note, if it were "Glock" style plastic, that would be a whole different story.

How can this be improved?

1. Need the vision to improve
2. Solid engineering
3. High quality materials
4. Advanced manufacturing techniques

As an example, here is a set of triggers made for M6-001:

What can be taken from this?  Simply that most rubber band guns, to date, have not had serious engineering or manufacturing techniques applied to them.  For them to become a serious sport, this needs to change.

Until next time, and as always, have a great day!

The Right Rubber Bands

One of the bigger problems with rubber band guns is their ammo.  Provided that a rubber band as a smooth release from a gun, it will leave without much problem.  However, that is where the problems start...

Rubber bands are typically made by extruding tubes of rubber, and slicing the end of the tube off to make each rubber band.  Because of this manufacturing procedure, rubber bands have a rectangular cross section.

Furthermore, most rubber bands have a high width/thickness ratio, making them rather "flat".  In our observations, this flat design catches the air in unpredictable ways resulting in two negative effects:

1. The rubber band decelerates rapidly because the width to mass ratio off, resulting in too much air friction with not enough momentum to carry it for a long distance.
   
2. The rubber band veeres off course erratically, resulting in a severe loss of accuracy.

From observation and testing, the most sensible rubber band for a rubber band gun would minimize this "flatness".  

The Heavy Duty Answer:

A rubber band with sufficient wall thickness, and minimal width would be ideal.  Despite searching high and low, we were not able to find suitable rubber bands, so we worked with a rubber band manufacturer to make a batch of a more ideal band.

4.5" long, 1/8" thick, 1/4" wide, very sturdy.

As it may be apparent from the picture, this rubber band flies very far, very straight, and very hard.  In fact, any doubts about the need for eye protection should be gone by glancing at this picture.

Thanks for reading, and as always, have a great day!
