The Lyman Series 17A Target Front Sight in the 17AHB configuration is a no-nonsense piece of hardware built for folks who take their target work seriously. Machined from a solid piece of steel, this front sight is designed as the natural running mate to a Lyman receiver or peep sight, giving you a crisp, repeatable sight picture that holds up shot after shot. The .404-inch height on this model fits low to the barrel, and the black finish keeps glare down when you're settling in on the bull.
The real story here is versatility. The 17AHB ships with eight interchangeable inserts that lock into place with a threaded cap, so you can swap between aperture and post styles depending on the light, the distance, and how your rear sight is set up. Aperture-style inserts let you center the target dead in the middle for near guesswork-free aiming, while post options give you a familiar picture for faster work. Being able to tailor the front element without buying a whole new sight is exactly why shooters keep coming back to this design.
This sight is built to drop into a standard 3/8-inch dovetail slot, which makes it a straightforward match for a wide range of rifles and Lyman muzzleloaders. It's a favorite for old military rifle matches, small-bore target guns, and classic rimfire trainers where a quality front sight makes all the difference. People have mounted these on everything from Mossberg target rifles to compact rimfire pack guns, often pairing them with a Lyman micrometer rear for a complete precision setup.
At the end of the day, the 17A Target Front Sight is a durable, mechanical solution with no batteries, no fiber to fade, and no fuss. Solid steel construction and a simple insert system mean it just works, which is about all you can ask from a front sight.
The 17AHB comes complete with a set of eight interchangeable inserts. The set includes both aperture-style and post-style options, giving you a range of hole sizes and shapes to match your target, lighting, and rear sight. They lock securely in place with a threaded cap and swap out in seconds.
This sight is machined to drop into a standard 3/8-inch dovetail slot, which is common on many target rifles, rimfire trainers, and Lyman muzzleloaders. If your barrel already has a 3/8-inch dovetail, it should slide right in. It's worth double-checking your dovetail dimension before ordering, since this .404-inch height model uses the standard 3/8-inch cut.
The .404 inch is the sight height, which is how tall the sight sits above the dovetail. Front sight height needs to work together with your rear sight so your point of aim and point of impact line up at your zero distance. Lyman offers the 17A in several heights, so this .404 model is the shorter option that fits low to the barrel.
It's built for exactly that. Lyman designed the 17A series as the companion front sight for their receiver and micrometer rear sights, so the aperture inserts give you a clean, centered sight picture through a rear peep. That combination is a proven setup for target shooting and vintage military rifle matches.
