Specter (sight)

The Specter was developed by Raytheon Six Sigma Product Development Team under Raytheon ELCAN Optical Technologies for the United States Naval Surface Warfare Center to fill the requirement for the "SOPMOD rifle kit SU-230/PVS Articulated Telescope NSN 1240-01-533-09039", development was started in 2003 with the goal to fix the general issue of transition between long range engagements/operation to short range engagement/operations(CQB) that would leave the soldier vunerable while switching optics. The solution found by ELCAN was to merge a telescopic sight with a red dot sight by using a rotating lens one side at 1x magnification the other in 4x that could be rotated by the turn of a lever. Development was finished in 2006 where it won the bid 9-1 and was adopted as the SU-230/PVS. Since more models have hit the market.[1] Such as the stripped down Specter OS line developed as a cheaper alternative to the more expensive DR line developed for SOCOM, it lacks the capability to switch magnification making it function more as standard prism sight.

SFOV4-C1 reticle made for the Specter OS 4x

The optic has 2 standard reticles both are a cross, feature a range finder out to 600m for 5.56x45 and 800m for 7.62x51, where they differ is in the bulletdrop design where the one called CX5395/CX5396 uses circles to denote the range, while the other called CX5455/CX5456 uses lines and also features lines for windage.[2]

The OS line features two different reticles one is the SFOV4-C1 similar to the CX5455 except featuring a "+" as the center of the reticle, the other reticle for the OS line is an ACOG like type reticle with a chevron in the middle known as CX5755

The Optic is fitted to the rifle with an A.R.M.S locking levers to a normal picatinny rail (MIL-STD 1913 rail) 70mm from the shooter eye. The optic is zeroed at 100m range the azimuth/ windage is adjusted by flathead screwdriver on the front right of the optic and the elevation is adjusted on the elevation at the back of the optic. The optic is capable of illumination, it can be turned on as a reddot or it can illuminated the entire reticle for night use. Illumination is turned on by turning the illumination dial on the left of the optic and the battery is located within the dial itself.

If the optic is a Dual Role(DR) model it has a lever in the middle that can be depressed and then pushed/pulled to switch between to set magnifications.[3]

The Tri-Role(TR) is the more unique optic in the line although operation remains mostly the same except the changing of the magnification now happens on the dial on the left of the optic, it can only have a red dot as illumination and features a different mounting solution.
