Ergo Rear Squeeze Bag
The Ergo Rear Squeeze Bag by IST Designs and available from CrossTac is replacing my old USGI sock filled with sand as my rear stock bean bag for shooting rifles off the bench or in the prone position (when using a bipod or front rest). The Ergo is constructed of a unique one-way stretch, tough, rubberized material that stretches vertically when you squeeze the bag (when it’s on its end). The Ergo has an oval cross section, and measures approximately 5.5″ long x 4″ wide x 2″ thick. The Ergo can be used in all three postions – flat, on its side, and on the end.
