I have the DPMS oracle (.223/5.56). I am about to order a 15" free float quad rail for it but before I did I had a question. Will the gas block be in my way or will I end up having to order a new one of those as well? It sits fairly low compared to the 2 piece rail I have on it now. but I do not have it in front of me to really look at it since I am at work.
