Review on 🔍 Easy & Rare Find: Hard Find Fastener 014973472795 472795 - A Unique Solution for Your Fastening Needs by Viswanath Lopez

Essential for building an AR rifle and keeps the locking spring and pin from flying all over the house. I've used this on 5 builds and haven't had a single spring or mount. Since you get a pack of five I gave two away to a family and one to a friend and kept two for myself. Both the ones I left worked fine and I would buy them again, but as long as I don't lose the two I left I should be fine.
