Anyone use these? I came across them at Walmart - and surprisingly fit the rail on the C9Comp. My intent is to fix a tactical light not a laser, but was unsure if the target caliber on the package is a red flag - e.g. use this on a heavier caliber and the assembly is liable to fall apart. Thoughts? I guess I could order 1" rings online that don't specifically call out the .22 cartridge.
