I really like the DD Omega Rails. I now have a 7" and a 9". As you said they go on easy, and really lock up solid. Good price, good product, good people.

I also like running a Surefire G2 or G2L in a VTAC mount ot the top rail. It is light, inexpensive, and works very well. The VTAC mount pulls the light in nice and tight against the rail so it's closer to the bore, and lower in profile to keep it away from barricades and other obstacles. I really like the looks of VLTOR's new mount too. It looks like the VTAC but is made of aluminum instead of plastic, but is priced accordingly. Although I have had no durability issues with the VTAC as of yet.
