I recently purchased six perimeter alarm tripwire devices from Fith Ops Co. at a cost of $30/ea. for a total of $180. These are devices which fire a 12Ga. blank shell when the trip wire is activated. Of six purchased, NONE worked or could be modified to make work. As supplied the firing pin is too blunt and the firing pin spring is too weak to fire the primer. I modified the firing pin profile, installed the strongest spring that would fit and tried every brand of primer available. All without success. Calls to the manufacturer went unanswered. Take heed and don't make the mistake I did.
Thanks for the heads up, John!

I have thought of making something like that with a rat trap.

I bought some dummy grenade triggers off of Ebay that use a shotgun primer as the noise maker, you should be able to find some there...

you can add tension to that spring by shimming up the butt end with bolt washers or a nut - about a 3/16 >>1/4 inch is usually max for procedure ... if you add anything to the striker bar try a sawtooth picture hanging bracket - line up your device under the spike - putting all that tension into a more concentrated point of contact helps >>>> wouldn't guarantee anything setting off a primer ....
the whole thing about any of these devices is that they are only an alarm warning - scare the crap out of someone for a second ... if you want to take it to the next level - same type of triggered striker device - but use a fuse liter cap instead - fuse burns to a pack of Black Cat firecrackers ... it'll draw return fire ...
