The Rock BR offers all the features found on other, more expensive bench-rest quality rests including coarse and fine elevation adjustments (from 5" to 9-1/4") and finger-tip windage adjustment. The cradle is supported on ball bearings, and the cast iron base has a 15" footprint, bubble level, adjustable forend stop and bag tensioning adjustment. At 15-1/2 pounds, the Rock BR gives you the stability you need to shoot the tightest groups possible. Accepts all Caldwell Deluxe Front Rest Bags and includes a 3" Lobe Bag (unfilled).
