507K direct mount to a G48 MOS. Ameriglo rear sight came in. I like the view! Might have to put some black sharpie over the rear.

Is the built-in rear sight on the 507K useful?

@Clusterfrack All but completely useless I think.

I forget what front sight I had, but it shot to POA with GD 124+p (when it didn't nose dive, that is.). Optic was direct milled and mounted by Primary Machine just before they stopped offering that service, and I opted to have the rear sight cut incorporated into the optic because I was using a 507k.
