Lyman 17 ATC Features The Lyman 17 ATC front sight is machined from a solid piece of steel giving it the rigidity and durability needed to stand up to recoil and field use without shifting or wearing loose. Its height is measured from the bottom of the dovetail to the center of the aperture ensuring a consistent reference point when paired with a compatible rear sight. The sight fits 3/8 inch dovetail rifles and muzzleloaders making it a versatile option across a range of traditional and modern platforms. Its Black finish keeps glare to a minimum during aiming which matters for both target shooting and hunting use. Eight target inserts ship with the sight including two post inserts at .050 and .100 inch widths one .062 inch bead insert and five aperture-type inserts for fine precision work. Each insert locks securely in place with a threaded cap so shooters can swap configurations without tools slipping or inserts coming loose during use. This range of options lets one sight serve multiple disciplines from peep-sight target shooting to faster field acquisition with the bead or post inserts. The Lyman 17 ATC Rifle Front Sight is available for sale at GrabAGun for shooters who want a durable adjustable iron sight for their dovetail-equipped rifle or muzzleloader.
