Primary Arms Slx RS 10

New for 2022, Primary Arms announced the release of a new micro red-dot sight, the SLx RS-10, which joins the current trend of micro optics for pistols. With a housing made from 7075 aluminum, the SLx RS-10 is robust despite weighing only 1.07 ozs. without the battery installed. The battery port can be accessed through a gate in the side, negating the need to remove the optic from the host firearm when changing batteries.

On the bottom of the housing, the SLx RS-10 features a Docter and Noblex styled mounting footprint, allowing it to attach to pre-existing mounts which follow that pattern. Using a 3 m.o.a. reticle, the brightness can be adjusted with rubberized buttons on the left side of the housing. The brightness can be adjusted from a range of daylight bright, all the way down to a night vision compatible setting. It has a suggested retail price of $200.
