I'm looking for ideas on replacing the front sight on my TC Omega. Soon after I bought the rifle I put a Williams peep on the rear. After breaking the fiber optic tube up front three times (it does not take much), I filed the front sight down to just leave the post. While this works fairly well in hunting situations, it is a little "blocky" for fine sighting on the range. I would like to replace the front iron sight and need suggestions. Any body else done this?
