RE: Legal muzzleloading rifle scope in Kansas
Legal muzzleloading rifle for deer (early season) - muzzleloading rifles and muskets that have open or peep sights, including fiber optic sights, that do not magnify the target, project visible light, or electronically amplify visible or infrared light, that can be loaded only through the front of the firing chamber with separate components and that fire a bullet of .39 inches in diameter or larger.
The RED DOT would be illegal. They do produce an electronical light. Also there are brightness settings on most of them so they would be illegal. From reading the law you are stuck with traditional, fiber optic, or peep sights.
