Boost the height of your rear bag with the Edgewood Rear Bag Spacer. Often times a 'higher' rear bag may be necessary to get 'lower' on the target, effectively bringing your muzzle height closer to the ground. We see this from time to time across the country at ranges that are built flat or you're shooting a bit downhill. The Edgewood Rear Bag Spacer is available in three sizes to fit Edgewood bags currently available: Original, Mini-Gater, and Gater.
