FB-34

Flashbang/less than lethal Grenade.

Use with a flash powder/flash mixture of your choosing. (Potassium chlorate/perchlorate + aluminum powder, potassium chlorate perchlorate+ magnesium powder, or any other popular flash powder mixes out there.) to create a loud report and a bright flash.

The top and bottom portions are meant to glue/epoxy into a 1.5" OD steel tube with a wall thickness of 0.065". (Or 38mm OD tube with 35mm ID.)

The perforations on the bottom cap are there to allow the bottom to rupture first and relieve pressure as to avoid DDT and end up turning the steel tube into shrapnel.

If steel tube is not available, there is also a plastic tube in the download pack to use.

Note: This is still a pretty good sized flash powder charge, and can definitely still hurt people, so don't use this for something like airsoft or milsim. It's only "less than lethal" because it's not specifically designed to produce dangerous frag.)

Striker driven via. rubber band or 270 degree torsion spring.
