Here’s my Weaver Kaspa 3-9×40 Scope Review

The Weaver Kaspa 3-9×40 exceeds expectations in some ways, and falls short in others.

In this review, I’ll show you why I think this might be a perfect starter scope for all you would-be hunters out there.

Let’s dive in!

Glass Clarity & Reticle

The clarity of this scope is pretty good. It’s crisp, clear, and bright. It won’t be as clear as a WaWa Zeiss or Leupold, but it’s better than what you get with a Bushnell or Sightron.

The reticle is not illuminated, but the 40mm objective lens brings in plenty of light.

The reticle on the Kaspa is glass-etched, and comes in Dual-X and Ballistic-X options.

A lot of people experience a pretty intense holdover with this scope. I found the same thing in my tests. I found myself aiming several inches above target to acquire a shot.

Eye Relief & Eye Box

The eye relief on the Kaspa 3-9×40 is 3.81-4.37 inches. This is definitely a plus on the Kaspa. More wiggle room for kickback is usually a plus.

Field of view is somewhat narrow compared to many other similar scopes, but that’s to be expected for something in its lower price bracket.


Weaver is typically synonymous with quality scopes. There are a couple of things that deter me from using this particular model, but one major advantage of the Kaspa 3-9×40 is it’s durability.

This scope is extremely rugged and durable. It’s shockproof, waterproof, fogproof, and has fully multi-coated lenses. Whatsmore, it’s pretty lightweight considering all the features it has. This goes to show that durability doesn’t always mean you have to lug around a scope that’s just as heavy as your rifle.

Elevation & Windage Knobs

The knobs on the Weaver Kaspa 3-9×40 are pretty easy to use. Max adjustment for wind and elevation is 50 MOA.

If you’re familiar with how to adjust a rifle scope, then you’ll see that the knobs on the Kaspa are a win for ease of use. They’re smooth and easy to adjust. They also have an indexing feature that allows you to zero in on specific yardages.

However, the major issue with this scope is its inability to stay zeroed properly. Out in the field, it just moves too much. The zero is unreliable. This is a major issue, especially for all you hunters out there who don’t have practice shots to make sure you’re aiming accurately.

Parallax & Magnification

The parallax on this scope is fixed at 100 yards.

The adjustable magnification on this Kaspa is 3-9x, which allows you to effectively use the scope in most situations.

Mounting & Rings

The Weaver Kaspa 3-9×40 is a scope that’s easy to mount. Mounting it on the side of the receiver allows you to get a good cheek weld without any trouble.

However, if you intend on mounting this on a bench or bipod, you may have some trouble getting a good cheek weld that’s stable and doesn’t shake all over the place.

For your convenience, the Weaver Kaspa 3-9×40 comes with both high and low rings as well as a sun-shade cap.


The Weaver Kaspa 3-9×40 is pretty affordable. You can expect to dish out around $100-$120 for this scope, which is a great price for the value it provides.

Is the Weaver Kaspa 3-9×40 for you?

The Weaver Kaspa 3-9×40 scope definitely has some great features. However, its inability to zero properly is definitely a downside.

In my opinion, it’s a great starter scope. If you are someone looking to get involved in hunting for the first time, this might be a good option for you. I wouldn’t recommend this as a scope for an AR-15 or anything tactical. It’s designed more for the hunter.

I recommend it for the amateur hunter because it’s lightweight, durable, easily mountable, has great glass clarity, and is easy to use.

  1. I bought one of the new, Chinese-made Weaver 3-9X scopes for about $50. The crosshairs broke free (rotated about 15 degrees) before the rifle that it was mounted on was ever shot! On the other hand, I have a couple of vintage Weaver scopes (a K3 and a K6W) that were made in the USA over 50 years ago that are still going strong. What a travesty to a great legacy.

  2. I purchased the Weaver Kaspa + Savage Axis 308 cal. RTH combo from Dicks sporting goods in 2018. While shooting just the other day 4/2023 the cross hair glass broke loose inside the scope tube and now I have a non functional scope. I have literally fired 100 rounds from this rifle and apparently this model Weaver scope can’t hold up to the recoil. Zero stars rating from me. I have a a vintage weaver scope K3 specifically that’s still going strong. Sorry Weaver but your company just isn’t what it used to be.
