So, thank you Dawson for making the .100 x .145 Fiber Optic front Sight that pins in just like the OEM HI-VIZ.
The HI-VIZ is ok, but too wide for the rear OEM Sight. The rear notch on my Factory OEM 63-5 is .123 wide & the HI-VIZ front is .125. This is not a good combo for me.
So, now I have a better front sight in that is also able to manually change F/O Rods to different colors (you can't do this on HI-VIZ Sights, because the tubes are coated with plastic)!
Now, I can have some daylight between the rear & front. The shape and placement of the dot is more like a Ed McGivern old style too, where the bead was small and at the top of the sight. If old Ed was still alive, I believe he would put this sight on his 63-5, or 3" 317.
The dimensions on the OEM HI-VIZ are .125 wide and .150 high. The Dimensions on the Dawson is .100 wide and .140 high.
Anyhow, just letting you Folks know that there is a great option now for your 3" barrel 8 shot .22LR Guns.
Oh, $39.00, no tax & free shipping.
