Front sight clarification...

[Brian Dick]

There are four types of front sight blades in eight different heights. Mk.1, Mk.1*, Mk.2 and Mk.3. Both split, Mk.2 and solid, Mk.1 front sight bases will interchange but you need the split front sight blades, Mk.1* and Mk.2, for proper tension in the solid, Mk.2, front sight base.

Buy a copy of Skennerton's S.A.I.S. No.2 which has the Illustrated Parts list and shows all of the differences. EVERYONE who owns a No.4 should have this booklet!
