Saw one in too hard basket repair room at my retailer recently. On first impressions it appears to be above board in terms of weight and feel, but totally put off by one rather small, bad 
in the ointment.
It is the very abominable excuse of a guide lug - very loosely mimicking the bolt head/extractor of the real deal. Secured to a very flimsy metal strip that gets notoriously hooked up against the guide rail housing causing it to lift off and separate. Ironically the housing features two screws to remove - something that is not featured on the real deal…foreshadowing perhaps? 
Shame DB had to skimp back (no doubt part of planned obsolescence) on this. But honestly for $850 that is not even gas, features no stripper clips and doesn’t fit the full 10 rounds - NO DEAL!
