“This MBA3 stock will not work on the Rock River Fred Eichler series II ar. The tube on the Eichler is a commercial tube. It did go on my mil spec AR's with no issues and its a great stock however I need one for my Eichler. I want to thank Jeff at Monmouth for the extra mile he went with his assistance and thank you so much for the hassle free return. I will be doing business with Monmouth in the future for sure.”
