USGI M203 Insight Technologies PSQ 18 Sight, Picatinny Mount

Description

These are Insight Technologies PSQ-18 Day/ Night Sights for the M203 grenade launcher. The PSQ-18 gives the user a single sighting solution allowing them to utilize their underslung M203 grenade launcher regardless of time of day or lighting conditions. The PSQ-18 features iron sights for day sighting, IR laser for night sighting, IR illuminator for nighttime PID, dual analog & digital range scale (shows elevation for ranging) and a picatinny rail mount. Starting at the iron sights we have a fixed front post with elevation adjustment. The rear sight has windage adjustments as well as two different sight apertures to choose from by simply flipping the desired one up. The IR functions have 3 settings: laser only, low laser + illuminator and high laser + illuminator. A selector switch located on the bottom of the device allows the user to select the desired mode. A Crane plug port is located on the bottom of the device next to the battery compartment, use of a Crane compatible pressure switch is necessary in order to operate the PSQ-18 as there is no on body activation switch. The lasers can be zeroed/ adjusted via 2 adjustment screws located on the unit’s main body. The PSQ-18 features a digital and analog range scale. Due to the low velocity of 40mm rounds one must angle the launcher to achieve the desired distance. A simple rotary knob located on the bottom of the device allows the user to adjust the angle of the sight in order to have the proper sight picture and angle on target. During daytime hours the user can make these adjustments by referencing either the digital screen or the analog gauge, at night when or when visibility is poor one can make easy adjustments by reading the digital screen as they turn the knob. The PSQ-18 utilizes a picatinny mount for attachment. Due to the odd configuration of the PSQ-18’s battery compartment an additional picatinny riser must be used to mount it to a picatinny handguard. A single CR123 battery powers the device and is placed within a compartment on the right side of the device. So whether your building a clone rifle that used one of these or simply wanna be able to “BLOOP” at night the PSQ-18 is for you.

*These units DO NOT have a visible laser, a night vision device is required to see the IR laser.*

**These PSQ-18 units require a Crane plug pressure switch to function, device does not have an external activation switch**
