This Aluminum Rest Set is a complete set front and rear setup for sporter and varmint stocks. The #3F Wide Owl Ear Front Bag is for use on the mechanical front rest. This bag was designed expressly to handle larger rifles with flat forends up to 3" wide. The famous #13B Rabbit Ear Rear Bag is 3-3/4" H to the bottom of the ears then tapers downward slightly towards the eagle. Includes a single hard bottom for added stability. It also has reinforced sides to keep the bag from bulging over time. 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. The new Protektor Model Aluminum Rest #60 is a lightweight and durable adjustable front mechanical rest proudly made in USA! This model has the standard top which adjusts vertically.
