Smitty,
Like I said from an earlier post, I also own this same gun. The answer to your question is No. Well, I guess with enough money you could do just about anything, but just take my word for it and forget about "converting" it into a DM.
Let me tell you something else. I also own a few remington with the DMs and I do NOT like the Remington DMs. They tend to rattle and make noise. Some gunsmiths say that Remington could have put in O-rings to solve this problem, but...Oh well.
