Are you sure your front sight is actually new, and not used?

If someone was using it as a 1,000 yard gun, it could easily have a filed-down front sight post. This is pretty common, so that the shooter doesn't have to put on 25+ clicks of elevation, keeping a normal stock weld, too. Note that folks do this only when they've got a gun that is dedicated to that one firing line.... they'll have their normally-sighted 200/300/600 yard gun, too.

Might not be the case with your rifle, but hey, you never know. A well-executed filing job and you might never know, other than the fact that you've got a little stubby front blade.

anybody know the actual height of a stock front?

 

Yes there is they are typically used for a scout type rifle sai and sei sell them. I am experiencing something similar with my rifle. I am bottomed out with nm front and rear sights and I am holding a 100 yard zero. I was told I need a taller sight. You seem to be experiencing the opposite maybe you need a shorter front sight. I can't think right now I am having trouble with my computer and I am in the middle of reintalling my keyboard and mouse software. Geometry is not on my mind right now. I will give it some thought but I am sure someone else will check in

 

If you are shooting light handloads, you will impact high. Try a different load too.

 

Hi Seaweed...

Sounds like you got it right (front sight too short so you're hitting high). And, SAI does sell a taller front sight, which I use on my Bush rifle. But it is significantly taller.

You may also want to also try other standard height front sights to see if it will help.

These are pics that I took of the taller sights that I purchased from SAI.

I hope this helps some.

Aloha,

That is one tall front sight. Any advice on where to look for a taller sight will be appreciated. Right now I'm going to the gun room to check out the ones I have already and compare them. Thanks

 

I have a taller NM .062 front sight that I'm willing too trade it mic's in at .583 base too the top of the blade, the std hight is .547 anyone interested?

 

Taller sight?

I'm with Tony Ben on this one. If you are using ammo with a light charge they will hit high. The reason being the bullet going slower leaves the barrel later then a normal round. Being later the muzzle is higher in recoil. If you follow me. Check the ammo before going to all the trouble of finding a taller sight.

 

Impact

Similarly, if you use a lighter bullet, and a higher powder charge, the impact can be as much as two inches low. Because the bullet exits sooner than a heavier projectile does, and does not face the forces of recoil and muzzle flip.

 

Chinese M14 front sight blades are usually much,much taller than USGI sight blades while retaining the standard USGI overall sight height.

 

The ammo is Port milsurp, and it holds tight groups out of this and other M14-types I have. No problem with the others shooting high. Another guy has the rifle right now,and I need to get it back to measure the sight blade height.

I'll keep a lookout for a Chinese front sight. Thanks.

Phil, what would you want to trade for the front sight?

 

check your PM

 

You will save yourself a huge headache if you just go with the front sight made for the 18" barrel. Why not nail the problem and put the correct part on the gun?

 

I measured the front sight, it is at .551. I did notice that the rear sight would not go all the way down (where the aperture curves down to the receiver it was hitting the receiver and would not go all the way down). I compared it to other apertures on my other rifles and it would not go as far down as those.

I compared it to other apertures I had in my parts bin. Some of those were relieved on the bottom so they would go lower, some were not.

I ground off the bottom of the rear sight aperture and it goes down to where I believe it should go. Now back to the range.

 

It could be the stock.

My S.A. Scout came with a heavy S.A. walnut stock. It grouped two feet high at 100m with the rear sight bottomed out. My problem was I already had a high front sight.

I put it in a G.I. synthetic stock and viola, problem solved. It now takes about 8 to 10 clicks of elevation to zero at 100m.

 

Good grief! SAI doesn't know how lucky it is this board's here, for the sake of its customers.
