This is the steel version of the OEM rear flip-up sight that comes standard on the KRISS Vector and DKM22 platforms, and it fits AR-15 style rifles with a Picatinny rail. What sets it apart is just how far out of the way it gets when folded. It sits a mere 14.22mm (about .56 inch) above the rail surface in the stowed position, so it disappears under an LPVO or red dot and won't crowd your sight picture. When you flip it up, it locks into place and gives you a clean, dependable backup.
The dual aperture setup is the workhorse feature here. You get a small 1.5mm opening for precision and bright-light shooting, plus a larger 4.5mm aperture for faster target acquisition and low-light situations. Both fold down completely flat regardless of which one you have selected, so nothing hangs up when you want it out of the way. The whole thing is machined from steel, which a lot of folks prefer over aluminum for backup irons since it holds up to abuse and keeps zero.
Windage adjustment runs off a large, textured knob that's genuinely easy to turn, even with gloves on in cold weather. It offers a wide range of windage travel for dialing in your zero, and adjustment works out to roughly 0.75 MOA per click based on a 14.5-inch sight radius. Installation is straightforward: mount it to your rail and torque the screw to no more than 2 Nm (about 17.7 in-lb) so you don't overtighten.
If you're running a KRISS Vector, a DKM22, or an AR-15 build and want a rugged folding rear sight that ships from the factory on the real deal, this is that exact part. It pairs naturally with the matching KRISS front flip-up sight for a complete iron sight setup or serves as a solid backup behind your optic.
It's the OEM rear sight that ships standard on the KRISS Vector and DKM22 platforms, and it mounts to any standard Picatinny rail. That means it works on most AR-15 style builds as well. As long as you have a mil-spec top rail, it'll clamp right on.
When stowed, it sits just 14.22mm (about .56 inch) above the rail surface, which is exceptionally low for a folding rear sight. It tucks nearly out of view, so it won't interfere with a red dot or LPVO mounted in front of it. Both apertures fold flat regardless of which one you have selected.
It has a wide range of windage adjustment handled by a large, textured knob that's easy to turn even with gloves on. Each click works out to roughly 0.75 MOA at a 14.5-inch sight radius. Elevation zeroing is typically handled by pairing it with a matching front sight of the correct height.
This is the steel version, which many users prefer over polymer or aluminum for backup iron sights because it stands up to hard use and holds zero well. KRISS also offers a polymer variant, but this DARSBL00 model is machined steel with a matte black finish.
