Wider and heavier than the Rock BR but with the same precision windage and elevation adjustment system, this 1000 Yard model is a great choice for long-range shooting. The large 18" footprint base and 24 lb weight create a rock solid shooting platform. Designed for large, heavy rifles with wide forends, this rest will accept all Caldwell Deluxe Front Rest Bags. Perfect for 50 BMG shooting. Includes a 5" wide 3-lobe bag.
