Hardpoint MK1 Carabiner Details The Hardpoint MK1 is the smallest of the Hardpoint series. A stainless steel-bodied carabiner with a wire gate, it is sized to fit on pant loops and similar attachment points. There’s also a webbing strap with a 1 in. strap pass-through and a split metal ring for keys or other small EDC items. It’s a handy little piece of hardware and good to have on hand.
