Knex Sniper With Mag

This is my Knex sniper i built with my brother. It is about 3 ft long and has a good range of about 40 ft with 1 rubberband.
Here are the pros and cons:

     Pros
     - high power
     - light for its size
     - easy to load
     - has a mag
     - sturdy
     - has storage mag too

     Cons
     -hard to keep bullets from falling out of the storage mag
Should i post??????????
