Knex Barrett 50 Cal

This is my new k'nex Barrett 50 cal.
Pros
50 foot range with two rubber bands
True trigger
Looks awesome
Comfy handle
Scope
Accurate
Removable mag
Cons
Stock is a little flimsy because I had to rig because I ran out of small green/black rods
Bipod sucks

This took me forever so tell me what you think and some suggestions to make it better.
Depending on how many people like it depends on if I post instructions.
Thanks for making this my first gun to reach 1,000 views!
