I received my BCM upper with DD Omega 9 rail last night! Thought I'd provide some detailed technical reviews for anyone else considering this product. First up, PRO's Free hat!! CON's My danged lower hasn't arrived yet All kidding aside, the upper assembly and DD rail are rock solid, appear to be fit and finished as one would expect, and the mags and BCG I ordered as well were all packaged to protect against damage or dings. Very happy customer as long as I get my lower soon!
