Yup,
Both mine pictured above came with the stock 5rd internal mag and trap door. The AICS units come with their own DBM kit pre-installed. It was between these or the JAE-700 from J. Allen Enterprises...
The JAE-700 is a great set-up, but there is a freakin mile long list of options to sort through to have one built. The AICS are simple, straight forward, and I'm really partial to the thumbhole grip anyway...
