Default Lee enfield no1 rear sight

Can anyone tell me if the adjustable rear sight of a no1 mk***, will fit on the mklll*? Being able to adjust the rear would be nice in lieu of Kentucky windage

The nomenclature can get a little confusing, but the No. 1 Mk III* designation did not come until the mid-1920s after the SMLE Mk III had been simplified into the Mk III*. Among the differences was the change to the non-windage adjustable rear right. So for sure a windage adjustable sight from a Mk III will retrofit onto a Mk III*. If you are specifically referring to the rear sight from a Mk I***, which is an updated bolt-charger SMLE, I can't say for sure.

Thank you gentleman, my mklll*, is a 1917, groups great, sub 2", on a good day, the planets align, and my over the hill eyes, are particularly sharp. It hits off to the right a bit, which drives me nuts.

If the windage is off, it's easy enough to drift the front sight post, which is the way it was done in service.

I do a bit of load development, so adjustable sights are a benefit

The No.1 *** should indicate that it was updated to the same standard as the No.1 MkIII so it should work with just swapping out the leaf and slide. The No.1 MkIII* was adopted during WW1 not the 1920s.

I have a few early Lee Enfields and have restored a few over time.

There is a windage rear sight for the Mark 111 which is called the backsight ,these were modified during the early part of WW1 to be fixed so that the windage is not working. Once in awhile you can still find a rear sight for the Mark 111 with windage.

In the Lee Enfield world, nobody would even think of installing the first variation of the backsight leaf on a Mark 111 while Mark 111 backsight leafs have been installed on the Mark 1*** rifles with the Irish CR serial number prefix

The rifle design itself was adopted in 1916, but the nomenclature Rifle No. 1 Mk III* was not used until about 1926. Prior to that the rifle was referred to as Sht. L.E. Mk III* (Short Magazine Lee-Enfield). The point I am making is that there no rifle was called No. 1 MK*** as referred to in the original post. I assume the OP is referring to a SMLE Mk I***

I put a windage adjustable rear sight on my Lithgow No1 MkIII* for CMP Vintage matches. Eventually I took it off because there was too much play in the rear leaf portion of the sight. I decided that I’d be better off using “Kentucky Windage.”
