The Williams™ 66708 WGRS-Black  Receiver Peep Sight is specifically designed to fit the Thompson Center Black Diamond.

This Williams™ WGRS-Black Sight Set 66708 fits the following firearms:

  • Thompson Center Black Diamond

The Williams™ Fire Sight Set 66708 DOES NOT fit any other firearms than those listed above.

  1. This sight is well made ... review by rick on 6/26/2017

    This sight is well made and very simple to adjust, very high quality

  2. Excellent sight but hard ... review by John on 6/26/2017

    Excellent sight but hard to sight in because of where the set screws are, under the peep. Which has to be removed to loosen the screws for elavation or windage. This is OK for the shooting bench but in the field it would be risky.
