These rails allow for the attachment of various accessories to the forend or buttstock of your rifle. Rails include mounting hardware for attachment to MDT Chassis kits.

The longer 6.5 inch and 5 inch rails include a built-in QD Quick Detach Sling Swivel (flush cup) Socket, NO QD SOCKET ON THE 2.5 INCH MODEL

They are designed to be installed on the underside of the chassis system forend. MDT’s 2.5” rail is also well suited to be used as a monopod rail on our SRS V4 buttstock.
