UTG® 4.2" ITA Red/Green CQB Dot with QD Mount, Riser Adaptor
The UTG® 4.2" ITA Red/Green CQB Dot with QD Mount, Riser Adaptor (model SCP-DS3840W) is a compact close-quarters combat sight designed for fast, intuitive target acquisition on rifles, shotguns, and pistols equipped with Picatinny rails. This 1x optic features a crisp 4.0 MOA red or green illuminated dot, unlimited eye relief, and a robust 38 mm aluminum tube for reliable performance in a wide range of shooting environments.
Built as part of UTG’s Instant Target Acquisition (ITA) series, this CQB dot sight is ideal for shooters who need quick aiming capability with lower demand for pin-point precision. Instead of lining up traditional iron sights, you simply place the illuminated dot on the target and press the trigger. With its quick detach mount, riser adaptor, and dual-color illumination, the UTG 4.2" ITA Red/Green CQB Dot offers a versatile, value-packed solution for close-range applications.
Key Features of the UTG 4.2" ITA Red/Green CQB Dot
This optic is loaded with features that make it stand out in its class. At the core is a non-magnified 1x optical system paired with a 4.0 MOA dot, giving you a clear aiming point without magnification. The dot can be displayed in either red or green, allowing you to choose the color that offers the best visibility against your background and lighting conditions.
The ITA CQB dot uses high-tech emerald-coated lenses to improve clarity, maximize light transmission, and reduce reflections. Combined with the wide field of view and unlimited eye relief, you get a bright, clean sight picture that supports both-eyes-open shooting and fast transitions from one target to another. This makes the UTG 4.2" ITA an excellent choice for defensive carbines, tactical shotguns, and dynamic shooting scenarios.
Red/Green Dot Reticle and Rheostat Brightness Control
The UTG 4.2" ITA Red/Green CQB Dot offers a single 4.0 MOA dot reticle that can be shown in red or green. A side-mounted analog rheostat dial lets you finely adjust brightness to match ambient light conditions. Instead of fixed brightness steps, the rheostat provides gradual, near-infinite adjustment, so you can set the dot intensity just right for indoor use, low-light environments, or bright daylight.
Lower illumination settings help minimize blooming and ghosting around the dot, which can improve perceived precision and make it easier to place shots accurately. Higher settings ensure the dot remains visible against bright backgrounds or under harsh lighting. The combination of dual-color reticle and flexible brightness control gives you a versatile aiming solution adaptable to many different situations.
1x Magnification, Wide Field of View, and Unlimited Eye Relief
This UTG ITA sight is a true 1x optic, meaning it does not magnify the target. That design is intentional for CQB and close-range use, where magnification can slow down target acquisition and reduce situational awareness. With 1x magnification and unlimited eye relief, you can comfortably shoot with both eyes open and maintain awareness of your surroundings while keeping the dot on target.
The wide field of view helps you track moving targets and quickly shift focus between multiple threats or steel targets. Parallax is set at infinity, which helps reduce perceived dot shift across common engagement distances. For rapid shooting drills, home defense setups, or fast-paced competition, the 1x, wide-view configuration of this sight is a major advantage.
QD Picatinny Mount and Smart Riser Adaptor
Mounting flexibility is one of the UTG 4.2" ITA Red/Green CQB Dot’s biggest strengths. It comes with a smart riser adaptor and a quick detachable tactical mount featuring an adjustable cam lever lock. The mount attaches securely to standard Picatinny rails, and the QD lever allows you to remove the optic quickly for cleaning, transport, or switching between different setups.
The riser adaptor adjusts the center height of the sight so you can achieve an optimal sight picture and, on many AR-style rifles, co-witness with standard iron sights. With the riser installed, the center height is set to give you a clear view over the front sight post while still allowing use of backup irons through the optic. If you prefer a lower mounting height for shotguns or other platforms, you can remove the riser and use the base mount alone.
Durable Aluminum Construction and Flip-Open Lens Caps
The UTG ITA CQB dot sight is built around a 38 mm aluminum tube, providing a strong yet reasonably lightweight housing. The compact 4.2" overall length and moderate weight make it suitable for carbines, shotguns, and pistols without overwhelming the firearm’s balance.
Flip-open lens caps protect the front and rear glass from dust, debris, and scratches when the sight is not in use. They are easy to open with a thumb flip when you need to bring the optic into action. A cleaning cloth is typically included to help keep the lenses clear, and the construction is rugged enough to handle regular range use and most field conditions.
Battery System and Illumination Controls
The UTG 4.2" ITA Red/Green CQB Dot uses a CR1620 3 V lithium battery housed in a side-mounted compartment. This location allows you to change the battery without removing the sight from the firearm, preserving your zero and saving time. The rheostat dial and color selector are positioned for easy access while maintaining a compact footprint on the rail.
Because the sight uses an analog brightness adjustment, you don’t have to click through preset levels. You simply rotate the dial until the dot appears at the desired brightness in either red or green. This simple, reliable design suits shooters who prefer intuitive controls over complex digital interfaces.
Compatible Platforms and Typical Applications
The UTG® 4.2" ITA Red/Green CQB Dot with QD Mount, Riser Adaptor is compatible with any firearm that offers standard Picatinny or similar rail space in the appropriate position. Common platforms include AR-15 and other tactical rifles, defensive and hunting shotguns, pistol-caliber carbines, and pistols equipped with rail sections for optics.
Typical applications for this sight include close-range defensive setups, home protection carbines, tactical shotgun configurations for law enforcement or security, dynamic competition shooting, and training scenarios that prioritize speed on target over magnified precision. It can also be used on airguns and airsoft replicas that share common rail systems, offering the same fast aiming benefits in those environments.
