Maybe a bored package stuffer played a prank.
Or someone went home, started searching their pockets for their Frammis spacer, and realized they lost it at work.
Serially folks. I have opened that picture in hi-res. I honestly would like to know what the heck is thaat thaang and why was it in a Ruger rifle package.
" I added it to my bad idea box as it would most assuredly have scratched the rifle something terrible."
I have received those gun safety locks of various styles. If used as directed, a lot of them would damage the finish or have potential to damage extractor, ejector, loading port or cartridge lifter if used as directed. (Seriously. I am supposed to open an 1892 action and thread a cable lock through the loading gate and out the ejection port? That lock still is still in its envelope in the box.)
There was a mandatory lock included with my M6 Scout but I could never figure out how it was supposed to work to prevent opening a hinge-action -- I guess the law mandated including a lock with every gun whether it was functional or not. I do use one of the cable locks - to secure my bike to my porch rail to deter any kids from the temptation of taking a joy ride (temporary lockdown not overnight storage). Right now it's just me and my cat, but I have lockable storage in case of visitors. Either
