Thank you for those, that's what I thought it would look like, one more thing if you look at the fore wood from the top is there cut outs or grooves where a top wood would have clipped on ?

That does not look to be standard barrel length, but you could order non standard lengths like extra long or short, if you ordered a short barrel it would most likely be fitted with a Carbine barrel which are 20 1/4in measured from the front ring & different profile to a cut down rifle barrel .

Not a normal front sight, if I get time I will try to put some up .

Sling Hook eyes are standard on nearly all (ever factory rifle I have seen) for sling fitting .

If the rear sight is mounted more than 2.5in forward of the front ring it is most likely a rifle barrel cut down, also I have never seen that type of military rear sight on a factory sportier .
