| 释义 |
The SUIT sight is a 4× telescopic sight with tritium-powered illumination, utilised at dusk or dawn. The full name is the L2A2 Sight Unit Infantry Trilux. The sight is not designed as a sniper sight, but was issued to designated marksmen. The sight was mounted on the L1A1 Self-Loading Rifle or GPMG. UseThe sight is an optional optical sighting system for the British Army's L1A1 Self-Loading Rifle and was also used by the Australians and New Zealanders. The sight has a lever to change between a short range mode (300 meters) and a long range mode (500 meters). A similar unit known as the SUSAT was fitted to the SA80 series weapons. ReticleThe reticle of the SUIT sight is of unusual design. Unlike the traditional crosshair layouts commonly used, which are in essence a cross intersecting the target, the SUIT has a single obelisk-shaped post protruding from the top edge of the sight so as not to obscure the target. The reticle is tritium-illuminated for low-light condition aiming. The radioactive tritium light source has to be replaced every 8–12 years, since it gradually loses its brightness due to radioactive decay. ManufacturingThe SUIT sight has an aluminium body, into which the eyepiece, objective lens and prisms are fitted as assemblies. The SUIT sight was developed in the United Kingdom by Royal Armaments Research Development Establishment (RARDE) and is manufactured by Avimo Ltd., now known as Thales UK. SpecificationsSUIT L2A2
