New williams sights. - Williams Gun Sight Western Precision Muzzleloading Sight, Standard Inline Set

I've used Williams sights on a some of my lever actions and all of my muzzleloaders. Love the old sights. The new ones seem like lighter material was used to make ? As far as fit and quality is good. Haven't had them in the field yet. Curious to see how they hold up to every day hunting. The old ones are bullet proof. Aperture rear / globe front.
