Airsoft blank grenade

thingiverse

Update 1-3-24: I redid the entire spoon and hammer design, made the spoon much thicker to accommodate the stronger spring. I also made the hammer pin further down as to get more of an edge strike on the primer as well as extended the hammer to make it easier to lock the spoon in place with the pin. You'll understand once you try pulling the hammer back. I made a few variations of the top shell, in various different sizes to include a shotgun primer (expensive) and a bigger hole to allow the use of a modified airsoft barrel for reinforcement for the blank (kind of sketch using only plastic to hold back a blank). I'll upload once I sort through everything.Airsoft grenade that uses .22 caliber blanks as a "flash" bang. Use outdoors only, DO NOT THROW AT PEOPLE. USE AT YOUR OWN RISK.The top for an 8.5mm airsoft barrel is to reinforce the internal area and decrease stress to the plastic. IT IS NOT A BARREL TO BE USED TO FIRE ANY PROJECTILES. Use of level 1 or 2 blanks ONLY.The reason for 3 different styles of hammer:One is 6mm to be used with a 5 pound AR15 trigger hammer springOne is 6.5mm to be used with a 3 pound AR15 trigger hammer springOne is blank to use other styles you may come acrossThe bottom of the hull is intentionally left open as to not cause fragmentation.Check local laws on legality of this item. Some states/countries may frown upon even owning one of these such as the United States. AGAIN!!! USE AT YOUR OWN RISK!!I assume zero liability for any injury/all injury that may result from the use of this device.Happy printing!This is not a firearm, nor any part of a firearm or destructive device. It is designed as a prop and is not intended to be used in any form of illegal activity.
