The Rock BR will help you discover the true potential of your rifle and ammunition. This high-quality rest is designed for the most accuracy-minded shooters around - Bench Rest Competitors - but everyone who wants the best from their rifle will benefit from the advanced design, precision machining, and finely engineered features of the Rock BR. The rest weighs a satisfying 15-1/2 lbs, thanks to its cast-iron base. Fine elevation adjustments are made from a large-diameter rotating wheel that glides on a set of ball bearings. Coarse elevation adjustments are made with a locking collar. The Rock BR's windage-adjustable cradle lets shooters make fast, smooth horizontal adjustments to handle wind shifts - especially appropriate for shooters using wind flags. The cradle features a sturdy bag tensioning system for excellent forend support and increased stability and accuracy. The Rock BR includes a free three-lobe synthetic bag that works especially well for flat-bottomed forends. The cradle has specially designed slots that allow users to quickly install or interchange any of Caldwell's Deluxe front Rest Bags to fit round-bottomed shapes. Every feature is designed to help you shoot more accurately - this is truly a rest that any quality-minded shooter will appreciate. Patent pending.
