The Rear Support System is a very easy to use product, it is very straight forward on how to use and it is made very well. We have used it mainly for shooting and sighting in a gun and target shooting when you need that extra stability. It is very lightweight and is very easy to store in a pack or on your side using the pouch with a belt. I first found this product when I took a client on an elk hunt and he pulled it out and I wasn't quite sure what it was, but after I saw him use it I got one for myself and it has improved my shooting while laying prone. I would definitely recommend this product to anyone that needs that extra stability while shooting.
