Yeah, I had a CVA Optima Pro and the sight was cracked when I bought it. An easy fix though. Just called CVA and they sent me a piece of the fiber optic. You just heat an end and make a tiny button so it won't come through the hole, push the piece through the holes, cut it about 1/16" past the last hole, heat and make a a button on that side.

The problem with making a button is you're making the sight bigger. I use super glue.

No, i don't believe you are correct. When using the fiber optic sight, one doesn't see the button. What you see is the light transmitted through the fiber. What is seen is the diameter of the fiber whether or not there is a knob. The knob doesn't play a roll in what the eye sees whilst sighting.
Also, using super glue is detrimental. The glue interferes with the light getting into the fiber optic, thus the sight doesn't appear as sharp or bright. |
Not sure why light wouldn't show through the button? Not that important to find out. FO sights are still blurry for me. I sort of line up the blurry colors.
Not sure a spec of super glue would even have time to penetrate. If it does penetrate at all. |
I normally use a butter knife and heat it up and lightly touch both ends. It does swell them slightly but nothing thats horrible mind you.
Time to take ol Slapper out and try some 250gr Thors in her with 90gr 2f Goex. Pretty sunny out so i most likely will just shoot 75 yards and see how she does. |

Coating the fiber optic tube makes it not so transparent on the ends, and dulls what one 'see' when sighting. It also hinders light from entering the sides of the tube. The super glue bond will eventually fail. The button, if done correctly won't fail, unless it is banged/busted. The super glue bond will eventually fail. |
I never keep a gun long enough for that. :p

Thats one thing i love about that hiviz set up i bought, you can change out the front sight easily if it breaks!
|
The heating and forming the button is how I was told to do it from CVA tech. And the fiber just fit thru the holes in the sight so the button does not have to be very large. Just slightly larger than the normal diameter of the FO.
Anyway, I normally put white out on my red fiber optic sights. Reason is the same as Muleys. The red appears to be a blur or double image for use old farts with poorer eyesight than our younger counterparts. |
