Hakkotsu Thunder B CO2 Sound Effect Review

Back around xmas I received the thunder B grenade system(Thunder B). They're main purpose is to produce large amounts of noise. They do a good job at that! They resemble the sound of a .22 long rifle round but deeper. They're generally used as flash-bangs for distraction. When I use them I fill them 1/4 of the way with flour to create a flash. If I could take 4 paint grenades or one of these onto the field, I would defiantly take these.








If you purchase one I would recommend placing a penny in the bottom of the CO2 chamber cap so the CO2 is Pierced better:

I will have a video of one or two going off either tonight or tomorrow.

are those even allowed on a paintball field?

I have heard of some fields allowing them, used alot by hard core mil-sim too. I would get some but I dont like the having to replace the shell everytime. Going to try to come up with one of my own and see how it works.
