Description
The NCStar DAB is a no-fuss reflex sight built for people who want a quick, uncluttered aiming point without dumping a fortune into optics. It runs at true 1x magnification with a 25mm objective, so you get a wide window and unlimited eye relief. That means you keep both eyes open, put the dot on the target, and press the trigger. No hunting for the right head position, no shadowing at the edges. The housing is black hardcoat anodized aluminum, and at right around 4 ounces it won't weigh down a light carbine or a .22.
What Sets the DAB Reflex Sight Apart
The headline feature is the dual-color reticle. A multi-position rheostat knob lets you flip between a red or a green 5 MOA dot, with three brightness levels for each color. Red tends to disappear against dark targets or foliage, while green pops in daylight, so having both on tap is genuinely useful depending on your backdrop. The LED emitter is easy on the eyes, and the lens carries an anti-reflective coating to keep the sight picture clean.
Mounting the NCStar DAB on Your Setup
This is where the DAB earns its keep for a lot of folks. The convertible base swaps between a Weaver or Picatinny cross-slot rail and a 3/8" dovetail, which covers the vast majority of rimfire receivers and airguns as well as tactical-style rails. Owners have run it on Ruger 10/22s, Marlin 60s, S&W M&P 15-22s, and plenty of AR platforms. It ships with a spare battery and mounting tools, so you can get it bolted on and roughly zeroed the same day it lands on your bench.
Who Gets the Most From the DAB
Think of this as a plinking, small-game, and training optic. It's a smart pick for a rimfire trainer, a truck gun, a range toy, or getting a new shooter comfortable running a dot before stepping up to a premium sight. For fast, close-to-mid range work where speed matters more than tiny groups, the DAB gets the job done and keeps things simple.

Frequently Asked Questions
What rifles will the NCStar DAB fit?
The DAB uses a convertible base that switches between a Weaver or Picatinny cross-slot rail and a 3/8" dovetail. That covers most rimfire receivers like the Ruger 10/22 and Marlin 60, along with AR-style rails and many airguns. If your gun has either rail type, this sight will mount up.
Does the DAB reflex sight show both red and green dots at the same time?
No, it's one dot at a time. The rheostat knob lets you select either a red or a green 5 MOA dot and dial through three brightness levels for whichever color you pick. Being able to switch colors is handy since red and green each show up better against different backgrounds.
What battery does the NCStar DAB use and is one included?
It runs on a single CR2032 3-volt lithium coin cell, which is a common and inexpensive battery you can find just about anywhere. A battery is included in the box so you can power it up right away. It's worth keeping a spare on hand for range days.
Is the DAB a good choice for a .22 or a first optic?
It's a solid fit for plinking, small game, and training on rimfire rifles or airguns where speed and simplicity matter more than sub-MOA precision. Many folks use it as an affordable way to learn how a red dot works before investing in a premium sight. For close-to-mid range fun, it does the job well.
