a friend of mine just recently purchased a Enfield No.4. we are both new to this rifle and when we took her to the range on sat we noticed that the rifle was firing quite high at a 100 yards, about a foot too high to be exact.

after inspecting the rear peep and front site we were unable to figure out if there was a way to adjust for elevation.

are these sights adjustable? how might we fix this problem?
 
Is it the flip type aperture sight with two aperture holes, one on each tab? If it is, I think they were calibrated to 300 yards and 600 yards.

You can't adjust them, but one thing you can do is track down a micrometer rear peep sight and replace your old sight.
 
The Lee Enfield #4 Mk 1, has 12 different front sights available to adjust your elevation to give you the appropriate point of impact with the type of ammunition that you are using. The problem these days is to find additional sites and also to find the tool to remove the old sight.Gun Parts Corp in the US will have additional front sights. I made my tool out of an old screwdriver. I flattened it then cut a groove to undo the screw.

This is one of the best .303 sites on the web http://www.303british.com/
Hope this helps.

thanks for the info guys. we had a great time at the range despite the sight problem.

im gonna have to look for one of these for my self.
 
It is instructive to remember that mathematicians designed the sights for most military rifles. Someone decided that infantry soldiers would engage the enemy at long ranges and the cavalry would close and finish them off. So, most rifles used in WWI have sights capable of firing at huge distances, like 1200yds. The closest distance those rifles could be adjusted was something like 300yds, and most had an round-top wedge shaped front sight post. Aimed at the visible part of an enemy in a trench, every single round went safely over his head. By 1939 the British were a little smarter, but old attitudes die hard. Your No.4 is only meeting specification.

The front sight on a No.4 is numbered. Larger numbers are taller, and will move the point of impact lower. On the front of the sight block is a wierd screw head. File, grind or hacksaw a screwdriver with the reverse shape of a conventional screwdriver to adjust or replace it.
 
I had my No.4 Mk2 out today and it shoots very low. I set up a clean target at 165 yards and I had to adjust my rear sight up 17 clicks to hit dead center. The rear sight is now reading 500 yards on the vernier adjuster(graduates to 1300 yards). With my battle sight (larger aperture) it is shooting low by almost a foot at 165 yards.

This leads me to think that the front sight is way too long (high).

My Front sight seems be a tad too high. It has an "F" and a "06" stamped on the top. Other than that is shoots great and is reasonably accurate.
 
From what I have seen, not all #4's have the odd clamping screw for the sight - take a look first before you worry about it.
I stole this from somewhere, not sure where. I usually include the URL when I archive so I can give credit to the author.

Elevation

All adjustments are made to the front sight beginning with elevation, because to correct up or down the front sight may have to be replaced with a different height. It makes no sense to get your windage on, only to have to replace the front sight to correct for elevation.

Zeroing at 25 yards, using the micrometer sight set for 200 yards, the Mean Point of Impact (MPI) should be 3/4 of an inch (plus or minus 1/2 inch) above the point of aim (POA).

Zeroing at 100 yards the MPI should be 3 inches above the POA.

Remember there are nine sizes of foresight available, each being .015 of an inch different in height. Each change of foresight to the next size, up or down, will change the MPI, up or down, 1/2 inch at 25 yards and 2 inches at 100 yards.

To correct high impact, replace front sight with a taller one, to correct low impact use shorter blade.

Examples:
Using a rifle fitted with a .0 front sight and firing from 100 yards, it produces a five round group 4 inches above the center of the bullseye. Then replacing the sight with a .030 blade will drop the MPI 4 inches, or

Using a rifle fitted with a .075 front sight and firing from 25 yards, it produces a five round group 1 inch below the center of the bullseye, then replacing the front sight with a .045 blade sight will raise the MPI 1 inch.
 
No.4 front sights- "who has sights"

Pops,

There should be different sight heights available. 0 would be lowest, I don't know how high they go.

Where would be a good place to buy some different sizes of front sights for my N0.4????
 
Bro you need a taller front sight
See what you can find on ebay
even better contact Queens Medalist in the parts forum he has a bunch for sale

2' at 100m is extreme
You need a significantly taller front sight.

Oh and by the way
0 is not the shortest sight. You can go into negative figures on front sights as well.

Go to the next HACS show in Burnaby. Ron Tyson runs a table with a bazillion small gun parts. He might have something.
