I have one on my SBE Steady Grip (The shotgun wedge) and really like it. Have only hunted with it for one season so far but works perfect. Going to order a couple more for several other turkey guns I have just to give me a little raise for my FF3 and my Tru-Glo iron sights, the exact reason you are trying to achieve. I think they are awsome and I think seem like they will hold up pretty well.
