I am new to the forum, so if this question has been asked over and over, I apologize. I recently purchased a 452 Scout for my 10 yr old son, who shoots on a competitive shooting team. He will need match/target aperture sights for a number of his competitions. I am struggling to find a front globe that will fit the 11mm dovetail slot. Also, I would really like to find a rear sight that attaches to the built-in dovetail base on the receiver. I have seen the Williams and Lyman rear sights that require tapping. Does anyone know where I might find a match aperture sight set that will fit the 452 Scout? I appreciate the help. Thanks.
