Rock Rivers are few and far between right now. They are very hard to come by. I had some parts ordered from them to build another upper, and I gave up waiting an cancelled the order. I found the parts from a Rock River dealer online and got 'em in 3 days from him.

Steve is a pleasure to do business with, and if his items are in stock you will have them in a few days on your doorstep. I've ordered 3 Rock Rivers from him now, and as soon as he gets in what I'm looking for, there will be another one coming from him.
