Wondering the same thing, love my DB-15 but i want to go bigger, been looking at a couple different AR-10s and wondering why a DB-10 is almost half the price of a CMMG or PWS. It kind of raises an eyebrow for me. Looking at a CMMG because i love the FDE color choice on the stock and grip where diamondback is just black and im afraid the magpul wouldnt match up with diamondbacks color if that makes sense.
