For my own curiosity, I decided to measure out the sight radius on all of my Milsurps. I'll list them from shortest to longest. I measured roughly to the nearest 1/2 inch.

M91 Carcano Cav. Carbine >>> 15'

Steyr M95 Carbine >>> 16'

Mosin M44 Carbine >>> 16 1/2'

SKS >>> 19'

SMLE >>> 19 1/2'

VZ 24 Mauser >>> 20'

Vergueiro 1904/39 >>> 20'

M38 Swede Mauser >>> 20 1/2'

M1 Carbine >>> 21 1/2'

SVT-40 >>> 22 1/2'

Swiss K31 >>> 22 1/2'

Swede AG42B >>> 23 1/2'

MAS 36/51 >>> 23 1/2'

FN 49 >>> 24 1/2'

M1 Garand >>> 28'


As I acquire more rifles, and therefore get more hands on time with a greater variety of guns, the little details interest me more and more. I believe in a global industrial mass war, it generally only mattered that a conscript infantry soldier had a rugged and functional rifle. However, as modern day shooters and collectors, we can really appreciate the small details.

Looking only at rifle specs on paper can be misleading. Only by handling and shooting specific guns do you learn their true user attributes. Mosins, Enfields, and Mausers all use 5 round stripper clips, but it only takes a few rushed reloads to see one system is far superior. Likewise when shouldering a Garand the sights seem to pop naturally into alignment, while I find I have to really 'scrunch' down on an M1 Carbine stock to align the sights. Finally, one really must volley off a 'mad minute' to appreciate that amazingly fluid and well positioned Lee Enfield bolt compared to a clunky Mauser.

Granted a lot of that is subjective, so lets get back to something we can measure, sight radius.

The carbines, naturally, come up much shorter, although I noticed that some certainly had room to stretch them back further on the barrel. I suspect they simply mounted the sights where it was easiest and most economical to do so.

Most of my rifles fall into the 'short', or 'universal' rifle category, and the standard seems to sit right around 20 inches. Take note the miniscule M1 Carbine has an impressive 21 1/2 inches thanks to a rear sight mounted at the back of the receiver. This would become a popular mounting point, and you can see it in my collection on the MAS-36, FN 49, and most impressively on the huge 28' radius on the classic Garand.

It is noteworthy that the Soviet SKS stuck with a more forward, barrel mounted sight. Likewise the AK would carry on this method.

Feel free to add to the list. I'm certainly curious about the sight radius on many of those full length, WWI era rifles.
 
Since we are talking sights, I should add a bit on my experience actually using these various sights.

First and foremost, the M1 Garand sights are down right superb. They seem to align naturally, have that beautifully long sight radius, and a clean and well sized aperture. Probably the best all around. I often group my Garand better than my bolt actions, and I think this is largely because of the sights.

The FN 49 and MAS 36 both offer a long radius and an good aperture. Both good sights, although the MAS 36 aperture is fairly large, as is the front post. Great for fast shooting, but not as precise.

When it comes to standard military open sights, my preference is a nice square u-notch and square front post. The K31 sights, for me, are the best of the bunch. The square angles just seem sharper and more precise, it's rather hard to define. A close second is the Vergueiro.

The Lee Enfield sights, and those "barleycorn" Mauser sights are rather low on my list. They just don't seem to be very repeatable or precise for me.

Likewise that Carcano sight, better left unmentioned haha.
 
Here's a few more:
1) Pattern 14: 32"
2) Charger Loading Lee Enfield (used in WW1): 23.25"
3) Mosin M1891: 27"
4) Turk and Spanish M93 Mauser: 25.5"
5) Martini Henry Mk II: 22.25"
6) Snider 3-band: 32"!!!!!!

My favorites for shooting are Lee Enfield No. 1 leaf sights and Mosin 91/30/ SVT 40 leaf. I find the P14/M1917 and No. 4 sights are hampered by the junk protecting the front sight- not a nice, easy to repeat sight picture. In any case, none of them are target sights. Put a Parker Hale vernier rear sight and tunnel front on a No. 4 and now you're talking.

Here is some more with a bit of a WWI focus, when there is two numbers it means depending on which rear sight setting used (for example the battle sight and adjustable sight on the Swiss K1893 Mannlicher are different).
Swiss Vetterli M70 Cadet 24-3/4"
Swiss M1897 Cadet 19-1/2"
Swiss K1893 Mannlicher 16-1/2" or 18-3/4"
Bulgarian M95 Infantry Rifle 26-1/4"
French M1907/15 Berthier 27-3/4" or 25-1/8"
Portuguese M1904 25-3/4"
Italian Vetterli M70/87/15 30-1/8"
Commission Gewehr 1888 24"
