Other people are dumb - Manticore Arms Snakeskin Panel For Transformer Rails 3 Pack, Black

These are meant to be used with the manticore arms transformer handguard. The handguard is configurable to swap out sections with either panels or mlok / keymod slots. This is why it doesn't come with any hardware. You are supposed to use the existing hardware that is supplied when you buy the handguard. You can use them with any other handgurds, but you have to purchase the hardware yourself.
