Lee-Enfield No.4 Battle Sights: What's The Actual Range? A test... 

Bloke, I'm sorry to say that you have reached the peak of excessive nerdiness. I don't think it gets worse than having a large collection of No.4 rearsights!

"I am not that good at mental math I am an engineer", and then uses a Swiss Army Knife as a hammer, sounds about right...

I live in the US so the first chargers i got for my lee enfield were the craptastic italian ones. I just got some surplus unused Indian manufactured clips from an australian seller on e-bay and they are heavenly in comparison. Doesnt really apply here but i just figured you would want to know one of your american viewers got the good stuff. Lol

Kinda late to the party here, but I have 1943 Maltby No4 Mk1/2 that was FTR'd in 1956. It appears that while at Fazakerly for the FTR they replaced the barrel with a five groove, put new dark walnut wood on it and fitted it with the Fazakerly milled micro rear sight. It is a real good shooter and I am a Handloader so I load my own ammunition. I have replicated the Mark 7 cartridge with the Sierra Matchking 174 grain. The Mark 7 spitzer bullet had a muzzle velocity of 2440 fps with a Ballistic Co-efficiency of .467 G1 bullet type. The Sierra Matchking has a Ballistic Co-efficency of .499 G7(boat tail) Bullet type. Using a ballistic calculator and some testing I found that using a muzzle velocity of 2300 fps the Matchking replicates the same trajectory of the Mark 7 cartridge and allows me to utilize the sights as they were designed. With that all said, I can tell you that after following the sighting procedure to determine correct front blade sight height and getting it zeroed at 200 yards that it is indeed 3 inches high at 100 yards. The Fazakerly sight allows for 3 clicks down from the 200 yard mark on the sight. If I turn the sight down 3 clicks till it bottoms out it is dead zero at 100 yards which does confirm that each click is 1 MOA at 100yards. With the sight flipped down and using the Battle Sight(Ghost Ring) for the most part its zeroed at 100 Yards. I say that because at 100 yards there is some paralax with that large of an aperture and you have to settle on a mean point of how you are indexing the front sight post and sight protectors within the rear sight "ghost ring" or battle sight. I find the Battle Sight to be most effective at 0-60 yards. At that range it is dead on. Past 60 yards I use the flip up sight adjusted all the way down and then adjust it depending on the distance I am shooting. It is dead on. Hope this helps. Let me know if you have any questions. Thanks for all your great work on these iconic rifles!

Correction of possible Error - I may have said that the No.5 front sights are lower - they seem that way cos they're mounted on the flash hider (and I don't have one to measure) but looking at where the 100 yd shots fell compared to e.g. the Savage sight clearly they're not. If I did actually say that (and I can't find it back quickly, and I'm not going to go through the whole thing), Sorry. And it's not worth the hours to find it, re-encode and re-upload for that when it's a minor point.

This is making me want to video my 6 or 7 Swedish Mauser rear sight variants.

That is a majestic lockdown beard. Othias might need to be nervous about his beard power ranking.

When you have more sights for a rifle than a museum would have

How do the lock-down-beard fare against an enemy like a cheese fondue?

I was taught by a Canadian Black Hat WWII soldier that two clicks below mark (bottomed out) on the No4 and No5 is a 100-yard zero. I've played this out on the range, and at full bench rest, you'll not get a tighter group with any modern open-sighted rifle (except the imperceptible small margin for error in Mauser battle rifles, but the power of the 7.92mm at that range is high. Also, the harmonic jump of an Enfield with a bayonet attached or not attached will move your elevation considerably. I'll have to reread whether these Singer sights were calibrated based on the bayonet trials and whether it was the 4 Spike of 5 Blade. You made my day, Enfields are so ridiculously complex and if we're honest when buying milsurps, the time spent learning everything and troubleshooting is valued added to the purchase!

I fell asleep to this.

Bloke, my L-E No. 4 Mk II arrived two days ago so this video is right on time and much appreciated.

Been binge watching all your Lee Enfield vids... just picked up a 1917 SSA made MK3* in pretty good condition for roughly 46 pounds or $60 US, absolute bargin. Cheers from South Africa.

Love it, and I still think that no7 is my 'most converted rifle' on RU-vid!

Great work here by BOTR! Brigadier J A Barlow's "Small Arms Manual" first published in 1942, with numerous wartime reprints, gives sight details for most .303 arms. It confirms the logical plan that the cartridge determines the battlesight setting, assuming barrel length is similar (but noting the longer barrel Ross uses the same battlesight range).

This is great work! Thanks!

Extremely interesting! I have a No4MK1 with the flip 2 position Battle Sight and a No4MK2 with the milled one

very informative really enjoyed this video hope you get more info on this .you and your stay safe stay well all the best from Scotland when the next batch of patches up foe sale seen the ones you have on jacket

I like how you went up by 6 (an oddball number) but quite confident. I usually go up by increments of 5, then go a 3rd time with a guestimate of how many icncrements of 5 clicks in any direction I need to tinker the sights to be on target.

More lee enfield nerd engineering videos! As someone whos trying to make a .3d print 20rnd trench mag for their enfield this is exactly the content I dream of.
