I recently had the opportunity to use a product made from Kopfjager Industries. Kopfjager Industries makes field portable rifle rests that will assist you in shooting more accurate under field conditions. The rife rest that I was using was the Reaper Rest. I mounted the rest on one of my tripods and did a little shooting with my 5.56 rifle and my 7.62 rifle. This rest will work with a bolt gun as well as gas gun. I was very impressed with how well this product worked. Its light weight and portability makes it something that every serious tactical shooter or sportsman should consider having in their inventory.
