I have a Marbles tang sight on my Lever Action Silhouette rifle. It developed a problem - the clicks are uneven - 15 clicks up doesn't always put me in the same place. So, I contacted Marbles and the immediately responded. I'm sending the sight back for repair or replacement...now that's customer service!
Thanks Marbles - I'll tell everyone how you help me get it back on target. I've gotten used to our "throwaway" society - its nice to find a company who stands behind their products.
