I needed a rear bag for shooting off the bench. I shopped around and found this bag on Mile Highs web sight? I figured if it didn't work I could use it to collect brass. When I received it I filled it with some cat litter I keep my truck during the winter and out to the range I went.
Works great I was able to line my scope on target squeezing or releasing my grip on the bag. The biggest well-made and the zipper looks heavy duty. You won't be disappointed
