The original #13 Rabbit Ear Rear Bag was invented by Protektor Model founder Basil Tuller in 1938. It is 2-5/8" H to the bottom of the ears then tapers downward slightly toward the eagle. Each ear is 2-1/2" tall and has a single stitch sewed in between them. We recommend using this style ear with most common hunting stocks used today. The taller rabbit ears allow shooters to use the squeeze technique to adjust elevation while shooting. This high quality top grain leather rear bag is for shooters to use while sighting in rifles or shooting ranges up to or slightly over 200 yards. The base size measures 5" W x 6 3/4" L. Made in USA 100%.
