I own a DR200, looks just like yours except I bought a scope mount (90.00) for mine.
I have put over 2000 rounds through the gun. I seriously don't know what it would take to jam the thing.
Supposedly the trigger, hammer, disconnector etc is a concern for some, since replacement parts are scarer than hen's teeth. I have heard that a complete replacement of the trigger parts with AR15 parts will do the trick.
Kinda on the heavy side, but if things go bad, I am grabbing the DR200 not my bushmaster.
Bumps like nobody's business too! There is a photo of yours truly bumping a DR200 with Mojo's Beta mag floating around somewhere on the web. I love the gun. 650 with 5 mags is a fine price.
