no.5 micro sight on a no.4?

[Peter Laidler]

Can't dispute what you've got in front of you Max except to say 'well, I'll be jiggered.........' At least I was partially right in that some No5 screws are only rolled half way down and on the No4, each click is approx 1MoA.

I'll look in the tech library and see what the score is

Querie solved. Who has the up to date No5 rifle parts list including amendment No4? Can't see the date but the front cover will be annoted WO-3111. Amendment No4 will be shortly after Amendment No3 dated May 1953. New page 7 (plus loads of other new pages that include the Grenade projector (an extremely rare item if eve there was!), the genade sight that was the same as the No4 and the shoulder pad and the now obsolescent short-thread screw and nut discussed above This amendment also shows the two screw bayonet grips and the now obsolescent Mk2 backsight with the usual WSE annotation.

My 40-BWS No5 has the No4 fully threaded screw/nut backsight
