Sig Romeo 7 VS Aimpoint Pro – Differences

  • Pro is lighter than Romeo 7.
  • Pro has a total of 10 brightness settings while Romeo has 7.
  • Romeo uses an AA battery. That increases the weight of the sight by a bit.
  • Romeo 7 is way smaller than Aimpoint Pro.
  • Romeo uses low-dispersion glasses in their lens.


Sig Romeo 7: The lenses on Sig Sauer Romeo 7 use LD glass. LD stands for low dispersion. This type of glass can work with less amount of light and make a brighter image. Their image processing is better than regular glass used by other brands. They provide vivid color accuracy with accurate reading under bright or no sun.

You also get an adjustable brightness setting on the sight. Alongside windage and elevation adjustments, brightness adjustment is also a good thing to have.

The lenses on this sight are fully multi-coated. They are scratch and waterproof. Glass etched reticles won’t move from recoil or accidental drops either.

Aimpoint Pro: Aimpoint uses a fully multi-coated lens and nitrogen-purged housing with their sights. The job of nitrogen purging is to ensure there is no moisture inside the scope. It also prevents moisture from leaking inside and fog the sight from inside. The outer exterior of the sight is IPX-rated. Making it submergible. Doesn’t necessarily mean you should do that.

While it doesn’t use LD glass, it’s still bright under the sun or no sun. It can also benefit from an NVD.

Clearly the superior glass here is in Romeo 7. But don’t count the Pro out of the fight. Even without LD glass, Pro makes up with a more adjustable brightness setting. You can easily hunt during the night with this sight.


Sig Romeo VII: The housing of Romeo is constructed from 6061 CNC aluminum. The machining is perfect and there are no visible anodization issues present on any of the sights. The same type of material is used in guns, aircraft, cases, and many other places. It’s durable and lightweight. Making it an ideal choice for sights. Rest assured, this sight is here to serve you for a long time. Don’t throw it under a running bus and you will be fine.

Aimpoint Pro: Pro is a patrol rifle sight. Meaning it also uses a tube just like Romeo. The tube is made out of aluminum. While Aimpoint didn’t disclose the exact variant of the aluminum, you can feel it’s not cheap when you touch the sight with your bare hands.

It’s definitely made out of high-grade aluminum that is also used in aircraft. It will outlast the warranty provided by Aimpoint. Yes, it’s that much durable.


Sig Sauer Romeo 7: Quality won’t mean much if the sight fails to perform simple tasks on the field. Thankfully, that’s not the case here. Romeo 7 performs excellently. You need to calibrate the sight to make it perform according to your needs. That might require some practice and getting used to.

Once you do, you will love every bit of this sight. It’s highly accurate with great bullet tracking. Recoil won’t harm the reticle of the sight either. Making it quite easy to place on the target right after shooting.

Aimpoint Pro: Aimpoint has delivered up to the mark products for years now. Their PRO series has great sights under the belt. Patrol sights will always have a tough place to fight for in the market. Aimpoint dominates the market by providing better performance over other options.

It’s highly accurate and gets extremely bright during the low light.


Sig Romeo 7: The height of Romeo is 56mm. The width is 51mm and it’s 119.4mm long. Making this a small sight compared to many other sights in a similar price range. One key difference here is, it’s heavier than most other sights in this price range.

Aimpoint Pro: Height of the Pro is 81mm. It’s 72mm wide and 131mm long. Overall, it’s way bigger sight than Romeo 7. It will depend on the user whether the size difference makes a huge issue or not. You still have enough space on the rail to put a magnifier or NVD in front of the sight.

Smaller sights are better for most hunters out there. But bigger guns can benefit from a longer and bigger crossbow in size. It will utilize the rail more and balance the weight better.


Sig Romeo 7: Surprisingly Romeo is much heavier than Aimpoint Pro. It’s smaller but heavier. As they say, a smaller package contains a bigger explosion. While it’s certainly the heaviest among the two, the weight balance is quite nice. It doesn’t feel toe or front heavy. Sure, depending on the battery you are using, the weight will feel different. But it will still feel balanced all around.

Aimpoint Pro: The weight of the Pro is 330 grams. That’s light considering just how big this sight is. Weight distribution on this is also quite nice. It doesn’t feel overweight on one end and lighter on the other. There is slight extra weight near the center back of the sight. But it’s not noticeable by that much.

If weight is your main concern, Aimpoint Pro eyes closed. If 20-30 grams of weight doesn’t make that big of a difference for you, Romeo 7 presents a valid argument.

Otherwise, it’s a hard-fought battle that nearly results in a stalemate. Both are good options for different budget people.
