Check my Sipriani Rifle too!
This is the first ever knex time bomb on the site!
It has a range of 3.5 ft.
The timer is about 22 seconds with two 64# rubberbands tied together.
Pros:
-strong bottom
-block trigger system
-pretty good range
-can keep up to 23 white rods in the spreader
-uses a firing pin
Cons:
-spreader isn't strongly attached to the bottom
For short:
It's a recommandable time bomb.
If you have any questions or problems please contact me on my orangeboard.
