For precision shooting, my front rest is a Bald Eagle with windage adjustable top. Turn a knob and the top moves right/left. The bag that came with this rest is leather and screws to the rest top. It is somewhat adjustable for fore end width but works best for +/- 3" wide fore ends with flat bottoms. I also have a #3 cordura front bag that works well with BR rifles. My current rear bag is a Protektor leather bag with owl ears and 3/4" thick leather base around the perimeter. This bag does not rock (like a rocking chair). I use heavy bank sand from Sinclair Int'l. more later
