Taurus 63 tang sight

[MH357]

I recently purchased a taurus 63 first one was shipped from factory when the QA inspector was sleeping anyway the second one functions perfect. I have not been able to get a tang sight for it. Taurus said they had some on order would take 3 weeks. When the three weeks were up I called back and got a different story of how they have not had them in a long time and may never. I can still find a few that fit the 62 and 72 rifles (online) will these fit the 63 also, I thank the long screws are what makes it for the 62 and 72 rifles, and believe I could use the screws allready on the gun for the 63 models. Does anybody know this or have a 62 or 72 the can measure, the 63 has a 2.2 inch spread CTC? Any idea? Marbles has one but thats almost half the price of the gun.

Thank Mike H
