The Rifles Only Rear Bag you know and love, now twice as thick for added stability. It’s revolutionary design provides the shooter with the most stable and manageable rear bag to date. Square in shape with 2.5 “ inch side walls, as well as a new bead fill are just two of the features that set this bag far and ahead of other rear bags. We can’t begin to describe the incredible stability this bag provides. It’s about as close to shooting off the bench as you’re going to get.
