Center hold front sight width and gap

[miacdc]

This has been discussed before, but I can't find the answer from old posts.

When using center hold for 10M AP, what is the preferred front sight width, 5 or 4.5mm? What is the preferred gap, narrow or wide?

The only way for you to get the answers to your questions is to try all the possible combinations and use what works best *for you*. But, my bet is you can use the standard front sight (4.5 mm?), vary the gap to several different widths, use each width long enough to reach a conclusion, and you will have your answer.

This, like everything else, is a very personal thing. There is no one way to set things up.

Wide rear gap, front sight apparent width of the bull.

front sight width of the black bulleye, is it 4.5mm (standard) or 5.0mm?

It depends on your eyes, fatigue,what shooting lens you use and the range light level.

Not aiming at the centre I wouldn't know for sure.

I would suggest however that the gap between the sights would want to be about the size of the black.

The width of the front sight would therefore still want to remain the the 1:2 or 1:3 aspect so would need to be fairly narrow i.e. 2.5mm

Good luck

It also depends on the length of your arm. Also, the apparent size of the bull will change depending on whether you are looking at the bull or the front sight, due to the change in the focal length of your eye.

You may wish to have about as much white showing on each side of the rear notch as half the apparent width of the front sight.

I personally like the 5mm width, but it ain't no big deal.

Written by a young man. Some of us are so old that our eyes no longer focus so there is no change in focal length. Others have had plastic implants to replace natural lenses with cataracts. Those implants are, for the most part, rigid and single focal length.

Lucky those who can still worry about changing focal length... :-)

The Norwegian text may be challenging, but the picture tells it all:

this is a bit controversial, but the guy is a respected NSF coach.
He has recently written a semi-official handbook that promotes the same idea. The frontsight needs to be about 7-8 millimetres wide for this to work, i.e. DIY :-) . I tried this myself for a while, it worked OK, but I have later used another "system" that is just as unorthodox.......

It is obviously one way of doing it, and no doubt it may work for some people. I would however suggest that that method is sub optimal for the vast majority of shooters and will result in a greater degree of errors because you neither tell exactly how high or how left / right the sights are. As always, try these things out if you think they may help you and give it a few sessions to evaluate it objectively.

Why would a large front sight for center hold not telling you "how high or righ/left", resulting in more error?

I don't get that.

[Doral]

He was assuming that front sight would get "lost" in black bulleye.

But if you use center hold regularly, you would know that is not the case.
