Which rear sight for No5 clone?

Max is right in thread 4.

Or...Jim was right in the first place...

Phil Rose in the UK has unissued No 5 sights - PM me and I'll send you his email address.

Thanks for the offer...
I do have a line on one here in the states... but if the deal falls through I'll let you know.

You're dead right BAR! Sorry about that. It's my age and lack of scholastic acvhievement in my early years reading class!

Incidentally, there are/were thousands of No5 backsights at the BSA works and later, the P-H works when it closed. P-H tried to utilise them and No4 sights for cheapness and just to get rid of them on the L81 Cadet Target rifle abomination. They only trouble was that after thay'd faffed around with them, cross treaded the axis pin hole etc etc and fitted them, they were no good as No4 or 5 rifle sights with the added bonus of being totally useless as L81 sights to boot. Alan XXXX, the desk officer involved with the acceptance trials of the L81 thing said he'd been told that both sights were a perfect match for the bullet trajectory using the long barrel and 7.62mm green spot target ammo. Mmmmmmmmmm

TCS-5, Thats a nice job you did, just shows all is not lost when seeing a cheap (I,m guessing it was cheap) sporter for sale.

Apex has the No5 rear sight. It's a wee bit pricey though.

Peter,
So are you saying there's no difference in the Mk1 and No5s sight except the No5 only goes up to 800 yds? But from 0-800 they are exactly the same? That is the marks are in exactly the same place up to 800 yds?

If so, how are they compensating for a shorter barrel on the No5 carbine? ....

Also seen an original No5 carbine with a No7 sight on it. What's the difference between the No5 and No7 sight?

Yes, $75 and from a private party in my state so there was no paper work needed... a double good deal.

Q1: What do you mean the Mk1 sight and the No5 sight? There is a No5 Mk1 sight and a No5 Mk2 sight. You've lost me
Q2: 'But from 800 they are exactly the same.........' You've lost me again. From 800 there ain't no graduations on the No5 rifle sight!!!!!
Q3: How are 'they'? 'They' don't! The specially graduated No5 sight is graduated for the trajectory and m/v of the shorter rifle characteristics and barrel harmonics
Q4: ..... phew...... No5 sight goes from 2 to 800yds (but you won't see beyond 80 or even 8 yards in the jungle believe me!) and a No7 rifle sight belongs to the .22" No7 rifle. This sight is a bog standard Mk1 No4 rifle sight BUT.... You ignore the 2 to 1300 yard markings on the face and set the sight to the 25 yard mark which is engraved on the left side during the conversion from .303 to .22"

Your rifle is a hybrid or good look-a-like compromise. So cutting to the quick, I personally suggest that you just fit a bog standard cheapo Mk1 No4 backsight and zero it in as regardless of the backsight the rifle will only ever be a good compromise at best.

Resurrected from no.5 micro sight on a no.4? topic in 2013 -

At least on these two examples (original sights), there appears to be a difference in screw diameter and pitch. Given the slightly coarser thread on the 800-yard sight, the "click value" would be some 10% greater than the 1300-yard sight if both were mounted on rifles with the same sight radius - except for the fact that the 1300-yard elevation screw is double-threaded, giving it an effective pitch approximately double that of the single-thread 800-yard screw.

On measuring the two sights shown, each click of the No.4's sight moves the slide .008" - vs. .0043" on the No.5's sight. Consequently, the 1300-yard sight gives very close to 1.0 MOA per click with the No.4 rifle's 28" sight radius while the 800-yard sight has a click value of ~0.66 MOA with the No.5's 23" sight radius and would yield ~0.55 MOA on a No.4 rifle.

This is what I mean... See the Mk1 micrometer sight verses the No5 sight?

Q2: 'But from 800 they are exactly the same.........' You've lost me again. From 800 there ain't no graduations on the No5 rifle sight!!!!!

You should read what I typed again. "But from 0-800 they are exactly the same?" Zero-800. It was a question not a statement.
You think you're frustrated? I haven't miss quoted you yet.

Q3: How are 'they'? 'They' don't! The specially graduated No5 sight is graduated for the trajectory and m/v of the shorter rifle characteristics and barrel harmonics

This is exactly my point. Thanks to Parashooter for the side by side comparison to confirm that from Zero to 800 these sights are not the same.

Your rifle is a hybrid ... So cutting to the quick, I personally suggest that you just fit a bog standard cheapo Mk1 No4 backsight ...

Peter,
Because you didn't understand "0-800" and miss quoted me, responding in a way that makes one feel like an *** or arse, I see no reason to try to answer any more of your questions.
And I know what my rifle is since I rebuilt it and I will put on the sight I see fit.

Thank you for your expert and friendly advice.

Now I'm beginning to understand why there are so many Lee Enfield discussion groups...
