I am planning on putting a rear aperture sight on my K31,Problem is the receiver is wider than your average bear its .750 approx from the rec. left side to the CL of the bore! I'm looking for a sight that would come close as possible to being centered.Abit off center is OK as long as I still have a few min. of right windage available after its zeroed.Are there any sights that would work for this application from the past or present?


Thanks,Tim
