Hello everyone. I'm in the process of putting together a DMR upper. I have been collecting parts for a while and now I am about to buy the railed forearm. I am not too concerned with building a mil-spec upper as much as building an accurate high quality rifle. I have looked at all the usual suspects and I am at a loss. What are you guys sporting? Pros and cons please. As always, I appreciate any input. Cheers, Splean
