Mount Selecting Charts Find your rifle on this chart to determine the availability of extension mounts for your rifle. The first two columns indicate the standard front and rear mounts, while the last two columns indicate the choices for the extension mounts. The length of the offset is indicated for each mount listed. If there is not an extension mount available for your rifle, you might want to consider using extension rings, which can be found elsewhere on this site. If you have questions or if you cannot find your rifle listed, please send us an email with a good description of your rifle and we will assist in finding a solution for you. Our Extension Mounts are only available in Matte Black at this time.
