Abstract: A writing instrument includes a body, a nosecone, and an adaptor each being of generally hollow tubular shape. The body, the nosecone, and the adaptor each have a first end and a second end. The first end of the adaptor is configured to slidably couple to the nosecone second end. The second end of the adaptor is coupled to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end where the mounting end is removably coupled to the second end of the body. The writing instrument includes a locking mechanism configured to selectively lock the nosecone in a storage position or a writing position. In the storage position, the nosecone extends and covers the writing end. In the writing position, the nosecone retracts and the writing end of the writing element extends beyond the nosecone.

Abstract: The writing instrument includes a body, a nosecone, and an adapter. The body, nosecone, and adapter each include a generally hollow tubular shape and an inner surface, outer surface, first end, and second end. The first end of the adapter is coupled to the second end of the nosecone. The second end of the adapter is configured to slidably couple to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end. The mounting end of the writing element is removably coupled to a second end of the body. The adapter includes a track and the track includes a recessed channel in the outer surface of the adapter. The body includes at least one protrusion that extends inwards from the inner surface of the body. The protrusion slidably engages with the track of the adapter.
