Check this out! its the RHINO RAIL SYSTEM for Remington shotguns. http://www.youtube.com/watch?v=NbtiG2xlY0c. These things are sick and surprisingly light only 22 oz.! They are very hard to get and can cost up to 400.00 email me if you want one and a WAY lower price. I only have a very limited amount left...they will go fast! [email protected].
