Peep Sight For Thompson Center .50 Cal

[Chizzy]

Hello:

I have a friend who lost the rear peep site from his Thompson Center ML. I don't know the model number, it is a very short barrel, .50 cal, break breech (to load the primer).

I believe it is a Williams peep sight with a Williams fire sight on the front.

Does anyone know what model of Williams peep sight would fit a Thompson Center ML?

Thanks in advance for your time.


Regards,

Chizzy
