The shotgun accepts both 2 3/4-inch and 3-inch shotshells and includes three choke tubes for tuning pattern performance. An adjustable rear sight with an integrated Picatinny rail works with the blade front sight to provide a practical aiming setup, and the full-length barrel heat shield and side shell holder add useful functionality in the field.
