In the early 1990’s FN Herstal had started work on the FNP90 they came to Ring Sights for an integrated light weight sight, over 90000 HC14 sights were produced by Electronic Optics.
These sights were NVG compatible with tritium night illumination.
For the US secret service, a special unit powered black telescope was developed with a black anodised metal housing this again had tritium dual illumination and NVG compatible. A version has now been specially designed for the Civilian PS90. This has a dual graticule, day Black or Green electronically illuminated but no tritium and sold through Kingsview Optical.
In the Mid 1990’s The army air Corp were looking for a sight to put on the M3M for door mounting on the Lynx, Ring Sights developed the LC40 -100 with IR illumination built in, this product is still in service on all UK forces Helicopter platforms for use with the M3M M134 M60, The sight now has a Variable beam Target illuminator VBTIL.
Propelled grenades due to their looping trajectory are difficult to fit with sights and still see the entire range. Ring sights developed with the help from ITDU a sight for the British army for the IMI bullet trap grenade, this was used on the SA80 and fitted around the Susat sight approximately 15000 supplied.
