1. They were easy to load
2. They were small
3. They were cheep
4. They looked easy to mod
5. They didn't have half bad power
6. They had gigantic air restrictors (AR), so they would fire even better without them.
I will show you how to do an easy mod to remove the AR and make the blaster fire better.
Step 1: Open it
First, undo all the screws on the cocking mechanism and remove it from the blaster. Then loosen all the rest of the screws and slowly remove the cover. This blaster is stuck together pretty well so you might need to apply some force to open it.
