Common Knowledge or Received Wisdom?

[Peter Laidler]

Simple. If a Mk3 of ANY date was later fitted with a high fore-end at an Ord workshop, it went OUT with a high sider and the C-O removed. C-O's played no part in the Military Training programme. Same as if an adjustable type back sight leaf was defective. If parts available (always a big if during wartime he reassures me.....) always replace with current fixed type leaf.

While we're here, he also mentioned some other bits such as get rid of the large nose cap screw by countersinking and insert later flush fitting screw. And something that I'd never heard of. New backsight axis pins didn't have a head, collar and retaining pin. It was just a straight pin with countersunk ends that could be opened to retain - like the Sterling SMG butt axis pins!
