The Holosun HS407K-X2 is a 1x open reflex pistol sight with a single 6 MOA red dot, built on the Holosun K footprint, which is the RMSc pattern.
No circle, no switchable modes, no solar panel. One large red dot on the smallest common slide cut, and everything else stripped out of the way.
The body is 7075 T6 aluminium measuring 1.6 x 0.98 x 0.95 in and weighing 1 oz, rated IP67 against dust and water and tested to 5000G, with a window of 0.58 x 0.77 in. A CR1632 loads from a tray in the side, rated for up to 50,000 hours, so a cell change never means unbolting the sight and re-zeroing it. Windage and elevation move 1 MOA per click with 30 MOA of travel each way, and twelve brightness settings split ten daylight and two night-vision compatible.
The X2 generation adds a lock mode that stops the brightness being nudged in a holster or a bag, and Shake Awake, which puts the reticle to sleep after the pistol has sat still and relights it the instant it moves. A 6 MOA dot is the coarse option: quicker for the eye to find at close range on a small pistol, but covering more of a distant target than a 2 MOA dot would. Note that there is no solar cell on the K series, so the CR1632 and Shake Awake are doing all of the work.
It mounts directly on hosts cut to the Holosun K or RMSc pattern, and on adapter plates machined to that pattern; an RMR cut needs a dedicated plate or a different optic. Switchable reticles on a similar body come with the HS507K X2 ACSS Vulcan, a full-size RMR-footprint alternative with Solar Failsafe is the HS407C X2, and more of the pattern sits in RMSc Footprint Red Dot Sights.
