Kriss Low Profile Flip-Up Rear Sight for AR-15, Steel Black

The Kriss Low Profile Flip-Up Rear Sight for AR-15 brings purpose-built simplicity to your setup. Originally engineered as OEM equipment for Kriss Vector platforms, this steel rear sight delivers the same rugged reliability and compact design that made it a factory standard. If you're running a modern AR-15 and want a backup sight that stays truly low and out of the way until you need it, this is a no-fuss option that doesn't compromise on adjustment range or usability.

What makes this sight stand out is its commitment to staying small. At just .56 inches when folded down, it tucks completely beneath most optics and top rails—no snag, no interference. That matters whether you're transitioning between optics on the range, stowing your rifle in a truck, or simply keeping your sight picture clean when you've got a primary optic running the show. The folded profile doesn't mean compromised sight picture: dual apertures give you options for different lighting and shooting distances, while a wide windage adjustment range lets you dial in precision without swapping parts.

The large, textured windage knob is textured for a reason—gloved-hand operation is built in, not an afterthought. Running heavier mitts in cold weather or tactical gear? You'll still make confident adjustments. The steel construction means this sight is built to take what you throw at it, from the range to the field.

Frequently Asked Questions

Is this sight compatible with standard AR-15 receivers?

The Kriss Low Profile Flip-Up Rear Sight is designed for AR-15 platforms and will mount to standard receiver rails. It was engineered as factory equipment for Kriss Vector firearms, so compatibility with other AR-pattern rifles depends on your specific receiver and rail system. If you're building or modifying an AR, confirm your receiver's rail configuration before ordering.

Will this sight work with my primary optic?

Yes. The ultra-low folded profile of .56 inches ensures this sight collapses well below typical scope and red dot heights, keeping it completely clear of your primary optic and maintaining a clean sight picture. It's designed as a backup or co-witness option that won't interfere with mounted glass.

Can I adjust windage with gloves on?

Absolutely. The large, textured windage adjustment knob is specifically designed for operation with heavy or tactical gloves, so you won't need to remove them to make field adjustments.
