I've owned both, still own the M92 (soon to be SBR). I do wish I wouldn't have sold the Draco and just kept both. the Draco has a chrome lined bore, standard 14-1 ak threads, ability to use standard akm handguards, and I did notice that the rear trunnion on the Draco is thicker (for drilling and tapping). I also noticed in my case the fit and finish was better on my Draco then my M92, I have a couple deformed rivets on my pap it doesn't effect function and there perfectly flush it's just a looks thing. That being said I love the M92, so much so I bought it's little brother the M85PV. The krink resemblance just does it for me, and if I'm going to sbr something I prefer a barrel a little shorter then 12''. If you have any specific questions post them, you really can't go wrong with one or the other, my only advise would be to look the pistol over carefully before you buy it.
