This is my new knex gun - The MFP9S V1.5
No bullet guide = No friction = More speed and power
Same ram rod
Same kind of mag
Different mag pusher - you have to push it up manually, or, you can have an elastic band.
It's not much different from the original but it has increased power and range - but - decreased accuracy .
Step 1: The Barrel
This is simple, you just take off the end of the barrel, and replace the edge of the inside with different parts!
Step 2: Mag Pusher
