Vic continues his Surplus Zone series with a look at the British SUSAT sight, principle by Britain on the SA80 and by Spain with the CETME Model LV and AMELI. In this episode Vic shows us how to refit a SUSAT with new elements.
The Sight Unit Small Arms, Trilux was developed in the late 1970s by the Royal Armaments Research Development Establishment. It is a 4x optic which uses a radioactive tritium light source, for use in low light conditions, which due to radioactive decay has to be replaced every 8-10 years.
The SUSAT is still in use with the British Army.
