its based on the clothespin triger from carbon.
i will use it in my new gun the SFTB (Small Far Thanx Boltsniper).

to load a clip, just push the 2 clothespins in, and slide the mag in.
the mag will be hold because it has got 2 holes in it.
to remove the mag just push the 2 clothespins in, and slide the mag out.
