2-3 clicks below the "200" yard range marking - use this to establish a working 100 yd zero. Mk 2 "L" Flip sight - marked for 300 and 600 yard ranges - applied to mid-war rifles from most factories as a cheap expedient - often changed in service for the next highest available precision / complexity sight as they became available. Mk3 fabricated rear sight assemblies and components are available - coming soon in the listing or ask for current stock. As indicated, marked F for Fazakerley, B for BSA, P for Poole Arsenals, N67 for Singer, CA / LB for Canadian Arsenals / Longbranch.Singer were the design originator of this sight type and produced the first units in the war - early, desirable and rare! The No4 Rifle and No 5 Carbine Adjusters Screws are different - different pitches of thread to deliver 2 MOA clicks on the different sight radiuses of each example. Shorter total threaded length on the carbine screws also.
Screws come complete with their corresponding threaded nut - universal fit into the hole in the cursor. Clickers featured a spring and plunger - or ball as available - I supply 2 balls in one order because "boing whizzz" happens. Spring and plungers / balls should be assembled with graphite grease - helps them "stick" during assembly giving you a chance!Lock pins act on a groove on the adjuster screw shaft but still allow it to rotate and act on the trapped clicker assembly - have fun and be patient! I offer rebuilt sights as listed - stripped down to base components, inspected for fit and finish, reassembled with graphite grease and tested to function as it should.
