CZ Comp Rear & 1mm FO Front Sights POA VS POI
« on: December 12, 2008, 10:09:04 PM »
I hope this is the proper spot for this.
I put the CZ Custom Shop recommended set of these sights on my Production CZ 75B about 5 months ago and have what may be a dumb question.

On a "Bullseye" 25yd pistol target, Where should the Fiber optic rod be positioned in the rear sites to hit center of the X-Ring?  Or better yet; where should the FO Rod be positioned to hit center of the USPSA head shot "A Zone"?

My 'Normal sight pic' is to put the TOP of the front sight Level with the Top of the rear sight and expect the bullet hole to be exactly split in half by the line formed (ON A PERFECT SHOT). 

I'm Shooting HIGH with my normal sight pic, which puts the top of the FO ROD even with the TOP of the rear comp sight  .  I have to bring the FO ROD about half-way down the notch on the comp rear sight to get a good POI.

Yes, I have adjusted to this, because I like the target acquisition speed , but I lose some time adjusting my normal sight picture.
Where there is a "no-shoot' covering part of the A Zone horizontally, I really have to slow down.

For fun, I challenge our RO to shot shells at 15 yds.  I usually hold my own, but I'm down two Cokes since I put on the new sights trying to 'guess' how to align them.

I appreciate your input.

even with the FO front sight...the top of the front lines up with the top of the rear sight..
if you line the FO with the top of the rear..you will shoot high..

I am trying this  modification to a 7.5mm high FO front sight. I stoned off the top of the sight to be able to line the FO up wih the top of the rear.


anyway that is my experience with FO front sights..and the main reason I have stuck with plain black.

Thanks eerw--  The metal at the top of your stoned-off sight must be mighty thin in the center above that FO rod, or is the FO rod flared enough to come up to the top of your sight?

On fast shots I don't see the black metal above the FO rod.

With my sights aligned the same as your pic, I would be 3+" high at 7 yards.  Where do you want your bullet hole with the sight pic you show on the FO sight?

They do sell a taller front sight--another $35

on this FO front sight I used the one for the Tactical Sport..which is 7.5mm high..by stoning the sight down to match the height of the 6.5mm front sight,  I am able to make my POI at the top of the dot.

yep. its thin..you can actually see the fiber through that post..

That's my goal too, but I don't think this sight is tall enough.

OK, here is what I ended up doing. 

I first tried holding the rod verticly and heating the end with a soldering iron.   OOPS Not a clear even ball.

I then tried holding the rod vertically and using heat from a Bic lighter.  OOPS,  Heat travelled too fast on 1mm rod.

Finally I put an old razor knife blade in a pair of vice grips and clamped the VGs in a vise so the blade was flat and level.  Using the Bic I heated the blade (HOT) and eased the end of the rod down vertically onto the hot blade.  SUCCESS,  it formed a nice even flare.

I cut the rod to leave about 1/16 out the front of the sight.  I then used the reheated knife blade to 'flatten' the forward end.  SUCCESS it was in nice and snug with a brilliant red circle at the shooters end.

There's probably a better way, but this worked fairly easily with good results.

eerw:  Thanks for the tips and the good pics .
