2. Best Crossbow Scope for the Money: Nikon Bolt XR

Nikon Bolt XR 3x32mm

Nikon is known for some of the highest quality optical equipment in the world. They offer dozens of specialized models for a wide range of budget. Nikon Bolt XR Crossbow Scope is one of their specialized crossbow scopes in the medium price range models.

Designed for shooting out to 60 yards, it has a fixed 3x power and 32mm objective bell. It is compact at only 8 inches long but is a little heavy weighing 11 ounces. This is a great scope that can be mounted on just about any crossbow for hunting.

Another great thing is the level of quality that you get with the usable reticle and design.

I recommend this scope to anyone who is getting started in crossbow hunting or anyone who needs a crossbow scope for general hunting.

It is legal everywhere crossbows are. It does a great job of providing a usable tool at an affordable price. You could easily spend double on other brands but not see any real up-tick in usability.



3. Best “Rangefinder” Scope: Trijicon ACOG

Trijicon ACOG Crossbow Scope

Though not a rangefinder in the common laser sense, the Trijicon ACOG Crossbow Scope has lots of features that make it one of the best in the market and by far the best range finding scope.

For starters, it is one of the lightest scopes weighing 5.89 ounces. For a young shooter saving on weight, that is incredible. The unit doesn’t need a battery but runs off a fiber optic cable design that has served the military for over a decade.

How it Works

The rangefinder works by using a simple cross hatch pattern that allows you to line up the animal and then measure the distance much like using a ruler. Then use the ballistically calibrated reticle to make sure the shot is true and clean, and let your arrow fly.

If there is a downside, it is the permanently affixed M16 carry handle mount. I’m not sure why they chose to design it like this, but there are adapter mounts to put it on a Picatinny rail or standard scope bases.



Factors to Consider Before Purchasing

If you’re in the market for a new crossbow optic, keep these few things in mind.


When you are shopping for an optic to top your new crossbow, start with your local regulations manual.

Carefully read the rules for archery hunters and the regulations for crossbow hunters. There’s a lot of overlapping rules in states that allow crossbows during archery season.

If electronic sights on vertical bows are banned during archery season, then an illuminated reticle or red dot sight on your crossbow will get you a nice fat ticket.

The rules are usually clear. But if they aren’t, shoot out an email to someone who can clarify. It can save you money and headache in the long run.


Point of Aim vs. Point of Impact

It’s important to remember right off the bat that crossbows aren’t rifles. The arrows they launch have the trajectory of a thrown rock, and most scopes can only predict where the arrow will go at one specific distance and closer.

Think of an optic on a crossbow like a single pin archery sight. Out to a certain distance, they work great. After that, you have a world of problems.


Weight, Bulk & Balance

The bigger the scope, the heavier it’ll be.

A big scope gathers light better. It is clearer to look through it but it has to be mounted higher. It can be difficult to get a cheek weld on the stock for proper shooting with a high mounted optic. Stick to a 1-inch tube no bigger than a 30 mm objective bell for optimal sizing.

The extra weight can be an asset though; crossbows are naturally front heavy because of the limbs. If you mount a scope low and to the rear, you can balance out the bow nicely and make it more comfortable to shoot off hand.


Types of Scopes

Red Dot Scope

There’s a certain kind of beauty in simplicity. That’s the ruling thought for red dot scopes. No magnification, no expensive ballistically calibrated reticles. Nothing but a clean, clear red dot ready to point the way to where your arrow will hit.

Parallax Error

The nice final point of red dot sights and why they’re so popular in the military is because no matter how you look through them, wherever the dot is the round will go. This is called parallax error.

It comes out when you see the crosshair of a traditional scope bend or a black circle around the rim when you look through an optic. Red dots don’t get that and for shooting out of a treestand or while stalking it can be a life saver on an awkward shot.

Red dot sights, where legal, are often the ideal sight for crossbows because they offer a darn tough and simple aiming system that makes it hard to miss.

Of course just like glass, you get what you pay for. So if you’re looking to upgrade the sight that your package came with, this might be an area to spend a little cash.


Magnified Scope

You have to determine where you’re going to use the magnification and how much you really need it.

Crossbows just don’t shoot very far but having a little magnification can help with things like trophy identification, threading the needle through a brush or picking out the edges of game in thick brush.

Importance of Magnification

If you’re older and still want to hunt, a magnified optic may be a requirement. The appropriateness of a scope with magnification is very much a case by case bases. But you have to keep in mind that more is often not better here.

The absolute maximum range of a crossbow is about 75 yards. If you can’t hit an 8-inch circle, about the size of a deer’s vitals, at 75 yards I kindly recommend you spend more time at the range.


Ballistically Calibrated Scope

Ballistically calibrated scopes are the ones with reticle designs that predict the flight path of an arrow. Believe it or not, multi-pin sights on a vertical bow are ballistically calibrated. You have a pin for certain distances and each pin is for a different distance.

BDC reticles are exactly the same, except you can’t adjust them so you can’t go outside the parameters that the scope was designed for or it’ll be off. If you get a BDC scope then make sure you memorize which crosshair goes with which range and practice, practice, practice!


Alternative Options

The market for crossbow sights is much larger than it was even five years ago. The major optics houses are making scopes for crossbows that are purpose driven and have special feature sets that make them go well with crossbows.

If you can’t find a scope you like and you can’t have a red dot, consider a rimfire or muzzle loading scope. Get one without a BDC and mount it up on your bow and run it.

Try to stay away from the cheap .22lr scopes because they break easy and collect water inside. But a premium muzzle loading or rimfire scope can be a last resort.


Finding the Right Scope for You

Sizing up a scope is much like sizing up a crossbow. The factors that have to be taken into consideration are the intended game, the shooter, and what ranges will the shooter encounter.

Of course, the bigger the game the more powerful the bow should be. This also means more weight and usually a greater challenge for the hunt. A scope that is lightweight and can be easily carried is suited here.

A younger or new shooter will also benefit from having a lighter scope but a bare bones approach at first is ideal. Select a scope that will allow the shooter ample magnification without hard-to-read reticles or difficult electronics sights that they’ll get hung up in the moment.

Think about who is hunting and what is being hunted before committing to a scope. Try to get hands-on with as many scopes as possible before you buy. That brand you’ve never heard of might be your favorite after actually seeing it.


More Helpful Tips

  • If you have rifles, mimic the scopes you have on your guns to make it simpler.
  • Have the features in mind — those you want and certainly don’t want. It’ll save you time in the long run.
  • Look for scopes that offer warranties, support and rebates to help you in the future.
  • Don’t be afraid to take advantage of the return policy if the scope isn’t the right fit.
  • Shop around to get as many demonstrations and hands-on trials possible with different scopes.
  • Learn to recognize the finer point and signs of quality on a scope. Things like finishes, detents and glass quality.

Try Before You Buy

Many outfitters and gear companies have display models that you can look at and test out before you buy. Some even have mock crossbows that you can shoulder and point at targets around the store. This is immensely helpful for several reasons.

Ordering online can give you a good idea of how big the scope is or how the adjustments work, but you can’t feel or test it first-hand. The scope is the only interface you have with the crossbow and having a hands-on demonstration in a physical store is useful.

Seek out brands that you might not have considered during your online search. More than once, I’ve seen people buy exactly what they never would’ve considered after seeing an actual model.


Know What You Need

The good thing about having a crossbow is being able to archery hunt with an optic. If you’re looking to upgrade the one that came with your package or you’re assembling your own setup, take some time and think over which optic is best for what you’re doing.

The optic is the only part of the weapon you get to interact with and it gives you all the information you get about where your arrow is going. This is one of the factors that will win you a trophy at the end of the day.
