Vortex SPARC AR vs Aimpoint ACO: Head to Head Comparison Review

We are headed back to the range for more testing with another Vortex red dot scope and a competitor.  This time we are looking at the Vortex SPARC AR vs Aimpoint ACO. SPARC stands for Speed Point Aiming for Rapid Combat and ACO for Aimpoint Carbine Optic.  These are both excellent red dot scopes. 

This test is our first encounter with an Aimpoint scope, mainly because of the price point on the Aimpoint products.  Aimpoint is a Swedish company and, while they advertise the Aimpoint ACO as an affordable model of red dot scope, the Aimpoint ACO typically comes in at almost twice the price of most other comparable red dot sights.

The adage, “you get what you pay for” may not exactly hold true in this case.  The reputation and our experience with Vortex optics certainly have left us thinking that quality and performance don’t have to cost twice as much.

Side by Side – Aimpoint ARC vs Vortex SPARC AR

The Warranty Issue

The warranty offered on a red dot scope can be a significant point in the decision process, especially if you are expecting to put a rifle scope into extreme conditions.  The importance of this decision is no different with a red dot scope. 

Vortex Optics Warranty

Vortex offers an Unlimited Lifetime Warranty on the Vortex Optics SPARC red dot scope.  The warranty is fully transferrable, and you don’t need to keep track of a receipt to make a claim.  The warranty specifies that:

  • If the optic becomes damaged the warranty will cover the repair or replacement
  • If the optic is defective, the warranty will cover the repair or replacements
  • The warranty is no-fault coverage.
  • The warranty doesn’t cover theft, loss, or cosmetic damage that does not hinder the performance of the optic.

Aimpoint Warranty

Aimpoint’s warranty is less generous and more restricted.  Aimpoint differentiates the warranty based on the use of the optic.  The two categories are personal use or professional use.  If you use the optic in competition, it is considered professional use.  The specifics of the Aimpoint warranty are:

  • The Aimpoint warranty covers manufacturers defects and workmanship for ten years when used for personal use and two years if used professionally.
  • Personal use is defined as use in a way that implies less exposure than professional use.
  • Professional use includes use in frequent competitions or daily exposure to military or law enforcement style situations.
  • The warranty offered by Aimpoint is not transferrable and must be accompanied by the original receipt showing the date of purchase.

Our take on the Warranty Issue

Vortex comes away in this category as the hands-down winner.  Users of the Vortex sights report that when a warranty issue arises, Vortex is quick to respond and helpful in meeting the expectations of the customer.  The unlimited nature of the warranty makes the Vortex SPARC a much better choice if warranty issues are your concern.

Construction – The Proof is in the Product

Both Aimpoint and Vortex use air-craft grade aluminum in the construction of the sight body.  It’s a dead-even tie in this category.

The next concern is the fit and finish of the sights.  Examining both sights gives no clear advantage to either.  The machining is precise, and the finishes are flawless—another tie.

Both sights use O-rings to seal the scopes and both companies nitrogen purge the scope during assembly—no clear advantage to either sight.

Batteries and Battery Life

The Vortex SPARC uses a single AAA battery for its power source.  Many people prefer the readily available AAA battery over smaller button style batteries.  The use of the AAA battery does reduce the expected battery life, but the availability of replacement batteries makes this a small tradeoff.

Aimpoint chose to use a DL1/3N battery.   The DL1/3N can be a problematic battery to find in the US.  There are substitute options on the market, but it is unclear how this will affect both the operation and the warranty if you substitute batteries.  The upside is the extended battery life of 10,000 hours of continuous use. 

Who Gets the Nod on Batteries?

For me, the choice is the Vortex SPARC.   I like the convenience of using a AAA battery.  The shorter battery life is not a concern for me.  I typically remove the battery from any powered scope before it goes back in the gun safe and a fresh battery goes in with the next use.

On the other hand, if I were carrying a patrol rifle in a locked mount or in a remote and hostile location where batteries may be a premium, the long battery life in the Aimpoint ACO is a definite plus. 

In this category, it is a toss-up depending on how you use your optic and where you may be at the time.

Accuracy – Putting Rounds on Target

Both red dot scopes will allow you to put rounds on target at reasonable distances.  Both feature a 2 MOA dot, excellent visual characteristics, and a good field of view down the tube.  However, the Aimpoint does gather a slight edge when it comes to adjusting your point of aim.

The Aimpoint AOC features ½ MOA clicks on the adjustments versus the Vortex SPARC 1 MOA clicks.  For this reason, we give the Aimpoint ACO a checkmark in the accuracy department.

Our Overall Takeaway

From a performance standpoint, either of these red dot scopes will perform admirably in the field.  We can find no appreciable difference in the capabilities of these two red dot scopes.  At this point, we have a neck and neck race

The significant differences that we consider are price and warranty.  From the price standpoint, the Vortex SPARC takes a considerable lead.  At about half the price of the Aimpoint, the Vortex SPARC delivers comparable performance and a much better warranty than the Aimpoint ACO red dot sight.

Based on our research and the comparisons, the Vortex SPARC sight is a definitive better choice.  We won’t disparage the Aimpoint ACO, but I can’t recommend that anyone spend two times the money to get the same features.

With That Said

It is still a personal choice that must make when choosing what red dot sight to mount on your AR platform. I hope that this review and comparison helps you make the best decision possible. If you have any comments, suggestions, or personal experience with these optics, please leave your comments below.  Our knowledge and experience are vital to broadening the understanding of others.
