If that's the Eagle model, I have one on each of my precision rifles, and also one on my tac shottie. I think they're great. Give you a bit of elevation off the stock, which usually puts your eye in a better place vis-a-vis the scope. They can be snugged down pretty well so they don't shift. They definitely take the snap out of heavy loads in the 12ga, and they are alot warmer in the winter than a cold rifle stock. Only downside is that you have to remove them to run a cleaning rod through the rifle, but they're velcro so not a big deal. I tend not to put too much crap in the one on my shottie since I find it unbalances the gun when I mount it.
