About The O-rings
All I request is a timestamped picture of your SPAS 12 (or LAW 12) just so I can feel better that these aren't being taken advantage of by people who don't need them. Take a picture of your SPAS with the date written on a piece of paper in the photo and send it to firstname.lastname@example.org and I'll send a couple your way. Free! Sending pictures or video of your SPAS 12 is always appreciated here, I'll always be happy to host SPAS 12 related images here for everyone to enjoy!
(Note: these are "in stock" regardless of what messages it gives you. Just email me, don't use the shopping cart for these!)
