Fixed Line Sight for Bren

[browningautorifle]

At longer ranges it's called the cone of fire and beaten zone and all machine guns have it. I don't think the Bren threw them around too much even from the later barrels. It never had the reputation even after changing to 7.62. With the mortar the pattern is called the "Probable error and dispersion" or the 85% zone. That is 85% of the rounds land close enough together to be effective. This sight could be employed on the Vickers, 81mm mortar as well so one class on this sight could teach three weapon courses the use of the same sight. To be honest, I'd think the static roles would be handled by the Vickers and the Bren would be used more in the lighter roles. But that's how the sight would be used.
