I Found the original package for my sight and its a
Toxonics TG-M-503X
Top Gun 50MM
Tooless-Micro-3X-Lens
It comes with the Threaded Pin Guard Housing.
You are proabably looking at an upgrade for your existing sight I assume???
Hoyt also sells this same exact sight made by Toxonics but its done in the Copper Color of last year model hoyts limb pocket color and they slap the Hoyt name on it and you pay extra for that Hoyt name on it[:'(]
