There is a full report on all of the sight blade variations if someone wants to resurrect it for Armenj. But, using a few words Arms, sight blade deflection is perfectly acceptable so long as the edge of the sight blade overhangs OR is level with the edge of the foresight block band - which yours is.... just!

Armourers are taught to accuracy test and zero rifles without a sling with the left wrist resting on a sandbag. That way, the rifle is free of all outside interference. Obviously at the big Field and all Base workshops, we had the special buffered Enfield Rest

I know some disagree with me here on the use of ammo but to test it first.initially for accuracy and zero (not necessarily the same thing) you must use the standard military Mk7 ball ammo. If it means that you've got to put yourself out to find some, then so be it.

Repeat after me 20 times.......... I know my car will run on chip fat, but to test it, I must use the correct diesel fuel
