The older buckmasters used to essentially be the Pre-Monarchs, of which I own quite a few, and they are EXCELLENT SCOPES! Today, the newer Buckmasters have even better glass, with 92% light transmission. While I love the Monarchs, Elite 4200s, Leupold VX-IIIs, and Zeiss Conquests, these scopes noticeably cost more money. As such, you will be hard pressed to find a better scope than the newer buckmasters for the money.
