To Peep sight or not ?

[ElDiablito]

Where can you buy a Gehmann PH510? From what I understand the Parker Hale model is needed to get the 7x32-40 threads for the Williams peep. I have been trying to find out what the diameter is because not much “room” for clearance on my Knight.

Ordered mine with the PH thread adapter on eBay

Gehmann 510 Rear Iris/ Aperture .5 - 3mm

The sight includes a new system of aperture control operated by varying the pressure of a steel tube against the central aim point.

I didn’t know you needed an adapter, though it makes sense.

From Creedmoore Sports:
Threading is 9.5mmx1. Not available in 10-32.

Maybe you can find an adapter?

Actually this looks like the correct one…

This iris is for use with Parker-Hale or Redfield sights and has laser engraved indications.

I run the gehmann with a 17ah front and can shoot amazingly well with it to 500 yards with swiss 2f and a 420 no excuses bullet.

The parker hale is what you want for the williams fp series.
