Hi all,

I have a No4mk1 that I want to lower the point of impact so I can put the bullet to POA at 100m. I currently have the tallest front post available for Lee Enfields. I still need to get about a 1/4" higher on the post. Its shooting approximately 5" high at 100m.

Any solutions here? Im not a welder, so I cant weld an extenstion to the front post and grind it down.

Thanks

You sure you need a whole 1/4"? I had to make a taller pin for my Mosin for the same reason. But just adding about 1/16" was enough. Too much by a little in fact.

And just to confirm you ARE using the rear sight with it folded down and using the short range peep hole? I believe that the flipped up movable peep starts out a lot further.

1. Ya, I roughed it out by putting a piece of hockey tape on the front post and cutting it off until I got to the height i needed.

2. Yes, folded down with the ghost ring
 
Is the rifle in military configuration or a sporter?

If it is military configuration - try and avoid making any permenent modifications that will affect the value, especially doing something like buggering up the rear sight (which depending on the Mk. can be rather pricey these days).

For a sporter, you could build up the front sight with something like epoxy or solder and then slowly sand it down until you end up with your desired result.

Which variant of the rear sight are we dealing with? Mk.I milled micrometer, Mk.II two position battle sight (300 and 600 yard), Mk.III stamped sight with sliding adjuster or the Mk.IV which is basically a Mk.III, but different... I ask, because the larger battle sight on the Mk.I/Mk.III/Mk.IV are 300 yard sights - so, to hit a target at a shorter range you need to aim down; 8 inches for 200 yards and further for 100.

You could soft solder an extension to the top of the front sight and then dress it down as required. A 1/4" extension does sound excessive. There is a formula for calculating the additional height required. Off the top of my head, it is the distance between the front and rear sights in inches divided by 3600 (100 yds. expressed in inches) times 5. If your sight radius were 25 inches, the required extension should be about 0.035 inches, or a little over 1/32 inch.
I have found that approach to be an effective way to correct elevation issues without making any permanent alterations to the rifle
 
If you are target shooting at round 'bulls' making the point of aim dead center works.. but holding on the bottom of the bull works too.

If you are hunting I think it is better to have it shooting high... and you don't have to cover your animal with the front sight to hit where you want.

A gunsmith can build up your front sight.

Its a commercial sporter. I wont hurt it any more then it already is, dont worry.

Its the No4Mk1 with the milled micrometer. I know that I need to aim lower I dont want to do that while hunting. Hence asking an easy way to raise the front sight.
 
Your choices quite limited - the battle sight was apparently 300 yard-ish with 174 grain @ 2440 fps +/- 40 fps (at least on an original No. 4). Might gain something by swapping to lighter / heavier bullets than you are using now, but lowering rear sight isn't really an option, which leaves raising front sight, as you know. (By the way, on most Lee enfolds, the flipped up aperture sight at its lowest setting is marked about 200 yards - closer range than the battle sight) Can be done by building up with solder, silver, perhaps epoxy, perhaps solder attach a metal extension and file to desired height. If you can't do yourself, likely will have to pay someone else. Don't think there is an Amazon.ca or Cabela's solution.

Im going to try the solder suggestion i think. Thankyou
 
What are you shooting? My enfield I'd have to set to 500 yards on the sight to hit with winchester super X 180g at 100y. With my current handloads I set to 125y and it's hitting good at 100y.
I'd be weary of some of the factory ammo. It'd may be way under pressure for manufacturer's liability shooting it in 100 year old rifles.

When you flip up the micrometer sight is the bottom flat or stepped lower in the middle? Someone here posted about the same problem and they filed the lower side of the sight flat to allow it to drop further and lower the point of impact, purists were angry but it did work. If you can’t raise the front sight look and see if you can lower the rear sight micrometer.

That "short range" peep is zeroed to 400 Yds. :)

Grizz
 
There is the possibility of finding a tall commercial front sight and with the judicious use of a file, modifying it to fit the military dovetail.

Thats an interesting idea I could try

I have a couple of front posts, I may see about epoxing a small length of copper wire to the top of the post (lying flat) so that from the shooters eye it appears as a "bead" on top of the post.
 
Take a short front sight and grind blade level to the base then cut a slot where the blade was. Hacksaw blade probably right width for the slot. Then make new sight and tap into slot and silver solder or other means to keep in place. I’ve seen old Winchester’s that the front blade was broken and this was done. Lol even seen pennies used as front sights. People did what they had too. A lot of them lead soldered in place but not nicest looking but worked

^ This looks like what I would do. In my junk drawer I have some old commercial front sights. A tall one of those would be about the height you are looking for.

The other thing you could do it buy one of those simple little Lee Enfield rear sights with the two holes in it (long and short range). Use solder to fill in the small hole (long range) and then drill a new hole, much lower. This would then be your 100 yard aperture. The other hole (what used to be the lower one) would then be your long range aperture.
