Vortex Sparc AR 1x Red Dot: 

Simple—Fast—Effective—Point and Shoot. When you boil it down, those are the advantages of a red dot sight. And that’s what the SPARC AR delivers - all in a durable, lightweight, compact, and ultra-clean package. Digital rear-facing controls for power and dot brightness offer quick access and are viewable from the shooting position. 2 MOA dot diameter promotes a precise point of aim and automatically returns to last dot intensity used when powered up.

Unlimited eye relief and parallax free, the SPARC AR gets shooters on target fast. The SPARC AR is waterproof, fog proof and shockproof for ultimate durability. Unit automatically shuts off after 12 hours to prevent accidental battery rundown and operates using a common AAA battery. Duty rifle, home defense, recreation, the SPARC AR is built to handle all your red dot needs.



• Fully Multi-Coated ‒ Multiple anti-reflective coatings on all air-to-glass surfaces increase light transmission.

• Bright Red Dot ‒ Display is highly visible in daylight.

• Brightness Settings ‒ Provides 10 variable illumination settings—the lowest two settings are night-vision compatible.


• Nitrogen gas purging with o-rings-seals delivers fog proof, waterproof performance.

• Compact and lightweight single-piece chassis

• Waterproof ‒ O-ring seals prevent moisture, dust, and debris from penetrating for reliable performance in all environments.

• Shockproof ‒ Rugged construction withstands recoil and impact.

• Hard Anodized Finish ‒ Highly durable low-glare matte finish.

• Operating Temperature ‒ Rated from -4 degrees to +158 degrees Fahrenheit.


• Multi-Height Mount System ‒ Includes a spacer shim that can be utilized to provide two different mounting heights: lower 1/3 co-witness (40 mm) & absolute co-witness (37 mm).

• Non-critical eye relief for rapid target acquisition.

• 12-hour battery power with an auto-shutdown feature to maximize battery life (typical battery life is 300 hours at maximum brightness and 5,000 hours at minimum brightness setting).

What is the model number of the Vortex Sparc AR red dot optic?
cvjagman748 on Feb 10, 2019
Can anyone explain why it takes "up to 15 days" to ship an upper? Buy a lower, next day service. Buy mags, optics etc next day service. Do they store the uppers in carbonate and need to defrost them for human appplication? Are they cast in granite and need to be chiseled out by magical forest gnomes with special upper receiver hammers?

What is a SBR stamp? I am new to building AR-15s but am very mechanically inclined & really want to custom build my own but sort of budget friendly lol.
Jerry W on Feb 19, 2019
BEST ANSWER: It’s a "license" from the BATF. You need it if you put a upper under 16" on a AR lower. You don’t need it if you put a upper under 16" on a pistol lower. Do your homework and make sure you understand the rules before you start building.
Is this a kit or a complete upper assembly (minus BCG and CH)?
Ninja C on Feb 15, 2019
BEST ANSWER: Complete upper minus BCG and charging handle.
Is this considered pistol upper or SBR?
Robert M on Feb 9, 2019
BEST ANSWER: If mounted on a pistol lower it is a pistol. If mounted on a rifle lower you need sbr stamp
Is the "mbus" sight set, that comes with this, plastic or metal ? I have seen both.

Great buy and great price
Just based upon initial impression without shooting it yet; it looks great. Perfect fit and finish. Pairs well with the PSA nib bcg and I replaced the stock flash can with a micro kak can to get a more flush look. Looking forward to shooting it soon.

Sleek and Petite, yet bold and intimidating !
Fast shipping. Ordered it on 02/10, it shipped on 02/14, and arrived on 02/21. Purchased this based on Tactical Toolbox’s review. The pictures on this page don’t do the justice. Sleek and petite, yet bold and intimidating. Perfect finish and great quality for a reasonable price. Don’t pass up on such a great deal.
