This is the upgraded version of the Excalibur I showed in my last instructable
Pretty straight forward design, holds 7 shots in the mag and the ram is easy to pull back cos its so short. The distance it shoots really depends on the number of rubber bands u put onto it so i cant really say.

You can see on the later steps how these two parts fit together
Step 7: Final Step
Shoots grey connectors. works best when the hole on the connector is towards the ram and the connecting bit is away from it.
