The Dr. Rear Bag is a top of the line 1,000 yard competition rear bag. It 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. Our exclusive Bumble-Bee Leather which is much stiffer than most leather aid in stability and helps prevent "rounding" of the bag over time. The standard spacing between the ears is a 1/2" triple stitch but it can be changed to fit any stock up an 1-1/2" wide. Available in three different ear styles and materials: Bunny(1-1/2"H), Mid (2"H) and Rabbit (2-3/4"H) in either Leather, Cordura or our popular Super Slick Silver Material. The Slick Silver material is a great option for shooters wanting a smooth alternative to baby powder or silicone spray. Made in the USA 100%. Base size measures 6"W x 8"L. Bag weight with Regular Sand is 13 lbs. and Heavy Sand 19 lbs.
