This Adaptor base Will fit onto a 3/8" rail on your rifle. This is then secured using the bolts to prevent it moving and causing inaccuracy. Made from a durable metal the Adaptor has an extended weaver rail on top. This allows accessories that use a weaver such as lasers, torches and scope to be attached.
Measuring 187mm in length the adaptor weighs 119g. This not only makes it easy to transport but means you don't feel the effect of the adaptor on your rifle allowing you to continue hitting precision shots.
