Sorry to reply so late, been busy. Like you may already well know now, the Phase 5 is one piece. All 7075 aluminum. The BHO is a standard BHO that you would get from BCM, Colt, DD, LMT, GandR, etc. The extension is securely attached. No glue. I don't care for the logo or the crazy cuts in the lever, but if you don;t like the idea of a bolted on BAD, then the Phase5 is your lever.
