Bisley 12 Gauge Trip/Alarm Mine including 5 Blanks

Restricted Item. Over 18 only
 
An awesome, low cost and VERY effective booby-trap which is very easy and quick to set up.

Originally designed for security measures for farmers, they are a great way to alert property owners of trespassers.
 
Simply secure to a post with the firing pin facing towards the ground using the screw holes, remove the firing washer from the chain and attach it to a line where you will issue the trip. To load pull back on the firing pin and put the Safety pin through the hole. Pull back again and load a 12 gauge shortie blank into the hole facing down. Finally, locate the washer in the ridge in the firing pin and carefully remove the safety pin. Your mine is now armed.
