This is the same front flip-up sight KRISS builds into their Vector and Defiance platforms straight from the factory, so you're getting a genuine OEM part rather than an aftermarket copy. It's a polymer-bodied backup sight designed for MIL-STD 1913 Picatinny rails, and it earns its keep by staying out of the way. Folded down, it sits right around a half inch (12.7mm) above the rail surface, which means it tucks cleanly under a red dot or LPVO without cluttering your sight picture.
The standout feature here is the adjustment. You get 50 MOA of elevation travel and 5 MOA of windage, dialed in 1/2 MOA clicks with a large, textured knob you can turn by hand. That wide range is intentional, since it lets the sight cover all sorts of height-over-bore and sight radius setups across different AR builds and calibers. Tactile and audible detents give you positive feedback both flipping up and folding down, so you always know where it's locked.
Mounting is straightforward on any standard Picatinny rail, and KRISS calls for a 2 Nm (1.48 ft-lb) torque spec on the clamp screw to keep it planted. Sight adjustments are figured on a 14.5-inch sight radius, and the front post measures 1.5mm across the top, giving you a clean, defined aiming point. At half an ounce, it adds almost nothing to your rifle.
This is a smart pickup whether you run a KRISS Vector, a DMK22, or a standard AR-15 that needs a reliable set of irons behind the glass. It does its job quietly, folds away when you don't need it, and gives you a real aiming solution the moment your optic goes down. Pair it with the matching Defiance rear flip-up for a complete backup setup that mirrors what KRISS ships from the factory.
Yes. While it's the OEM sight for the KRISS Vector and DMK22, it mounts to any standard MIL-STD 1913 Picatinny rail and is designed to fit AR-15 platforms. The wide 50 MOA elevation range lets it accommodate different height-over-bore and sight radius setups, so it adapts to most builds.
No tools are needed for adjustments. The large, textured elevation knob turns by hand, even with gloves on, and gives you tactile and audible detents so you can feel each click. You will want a wrench to torque the mounting clamp to the recommended 2 Nm when installing it.
Folded down, it sits about a half inch (12.7mm) above the rail surface. That low stow height keeps it tucked out of your sight picture, so it won't clutter the view through a red dot or magnified optic when you're not using it.
Yes. KRISS offers a matching Defiance low profile rear flip-up sight that pairs with this front unit for a complete backup iron setup. The rear features dual apertures, a 1.5mm and a 4.5mm, for different lighting and shooting conditions.
