ATTENTION VENDORS ! ! ! 50ea. Bulk Pricing ! ! No shipping cost. I cover eBay, PayPal, USPS shipping and Insurance cost. These are a DIY alarm system or what ever you choose to make. All have been cleaned (tumbled for 6hr), checked and have not been modified in any way since I have had them. The pictures are typical of the ones you will get. If you require a picture of the ones I will send just let me know and I will provide. Ask any questions prior your purchase, since they are "SOLD AS IS". You can check on YouTube what some are making out of these. Since I have not made any modification to any of them they are being sold as scrap. As pictured, you will see all spring and hammer is in the cocked position. If you modify and use a primer, the primer will produce a spark and flame so keep it away from anything that might catch fire. The will be shipped in the lowered position with out wire in them. Takes very little time or equipment to modify to make trip wire alarms. At this price and a little effort they make a high profit on sales at Gun Shows, Flee Markets or at your shop. Perfect for early warning systems and GREAT for paintball and airsoft games. They allow you to stop that Run and Gun game and really enjoy the sport. They are ideal for protecting the gardens and flower beds from deer. The 209 primer set up is cheap. Primers are about $3.00 for a 100ea. primers. They were cocked as a demo only. They are getting harder to find these without modifications. I reserve the right to use larger shipping containers for multi orders. Thanks and God Bless.Update: This is information passed on to me by others that have bought and used. During used they did not use anything to keep the pin from falling out. Results, lost pin. A quick fix to prevent this is tape, hot glue, JB Weld or even replacing the pin all together with a split pin / cotter pin or small bolt and nut.. The split pin / cotter pin is an easy replacement.  Just so you know.
