At only 11oz, the Channel Lock gives you the most versatility you can get from any piece of hunting equipment. Its offset multi-channel design is like no other support bag on the market. It allows the shooter to use opposing channels to lock the bag into place when shooting from blinds, fences, shooting houses, rocks, logs, branches, and rails of ladder or climbing stands. The opposite channel creates a groove to seat your rifle with rock solid stability. Makes an excellent rear bag and is handy as a cushion, glassing and even a pillow for that midday nap.
