The Dr. Rear Bag is a top of the line 1,000 yard competition rear bag. It's used by many champion benchrest and competition shooters alike. It is 4" tall to the bottom of the ears and slopes downward towards the eagle. This bag has extra long ears which helps the gun track incredibly well and an integral doughnut bottom comprised of 4 layers of stiff leather to provide a rock solid base. The exclusive Bumble-Bee Leather is much stiffer than other leather which aids in stability and helps prevent "rounding" of the bag over time.
