Pretty cool shooting bag - Armageddon Gear Fat Bags

This bag is very versatile. I recommend watching some videos on different ways to use it. There is a bungee with a carabiner to clip it to your belt. This allows you to change rapidly. You can squeeze the bag under either arm to get a more stable stance standing or under the rifle from a supported position. There are also ways to use it on the prone or sitting positions. The velcro straps allow it to strap to the bottom of your rifle's forearm. It is very light weight which is good on many situations. You can't change the fill because the bag is sewn shut. Its a pretty good bargain for this bag.
