Whether you’re just starting out with crossbows, or even if you’re a veteran x-bow shooter, you might find that the most perplexing parts of setting up a new scope is sighting it in. It’s important to get it done right, since this is key to your accuracy being dead-on and getting those all-important kill shots, but it can be a frustrating process if you don’t know how to do it right.
Sure, there are some scopes out there that won’t sight in properly no matter what you do. If you’ve done your research and read reviews of the scopes, though, this hardly is ever the case. Instead, it’s usually a matter of technique. Follow these guidelines carefully, as well as our guide on mounting your crossbow scope to begin with, and you’ll find yourself getting sighted in quickly and easily. Here’s how to sight in a crossbow scope:
Gather what you’ll need
First, make sure you have everything you’ll need at the range.
Your crossbow, with the scope already mounted and aligned.
The instruction manual that came with your scope
Screwdrivers for adjusting the windage and elevation on your scope
A chronograph (if needed; read this entire how-to and decide whether or not you need one)
A crossbow rest, bipod, and/or tripod
Arrows (at least 4)
Targets
Binoculars or spotting scope
Sighting in the crossbow
Follow these steps to start off the process of sighting in your crossbow.
Set up exactly 20 yards away from your target.
Cock your crossbow using a rope or crank aid.
Seat an arrow on the flight rail of your crossbow.
Align the top-most red dot or reticle in your scope with the bull’s eye.
Squeeze the trigger quickly, using just the tip of your finger. Moving your entire palm or arm will ruin your accuracy.
Next, approach your target or check it with your binoculars or spotting scope. Is the arrow on the paper? If not, you need to “boresight” your crossbow again by looking down the flight rail and aligning it with the bull’s eye. Then, adjust the elevation and windage to get you close to the bull’s eye.
Finally, for this part at least, fire three more arrows at the bull’s eye of the target.
Adjust windage and elevation
Next, you’ll adjust the windage and elevation of your scope based on how far off center your shots are.
Approach your target, and estimate how many inches your arrow group would need to move for all the arrows to hit the bull’s eye. For example, if your shots are 1“ low and 2” left, you will need to adjust your scope up and to the right.
Retrieve your arrows, and return to your crossbow.
Remove the protective caps from the scope adjustment knobs and make the appropriate changes. You should follow the instructions that came with your scope, but most crossbow scopes will move the arrow point-of-impact by 1/20″ for each click at 20 yards.
Fire another salvo
Now that you’ve adjusted your scope, you can fire another round of three arrows.
Stand at the same 20-yard distance from the target.
Align the top-most dot or reticle on the bull’s eye.
Following the same technique as above, fire a total of 3 arrows at the target.
Check the grouping
You should find that your arrows land much closer to the bull’s eye this time. You may find that you over-corrected a bit, or maybe didn’t correct enough (especially if you lost count of the clicks). You can make more adjustments, as necessary, and repeat the process until your scope is perfectly sighted in.
Calibrating the range compensation reticles
Many after-market scopes offer range compensation reticles, but these have to be properly calibrated or they’re worthless. In order to calibrate these markers, you program in the velocity of your crossbow with your arrows of choice, and the scope’s internals do the rest. Do not ever rely on the stated velocity of a crossbow according to the manufacturer, though, or you won’t get the same level of accuracy.
Set up your chronograph according to the manufacturer’s instructions.
Fire an arrow through the chronograph, and note the velocity.
Repeat this process three more times, noting the velocity each time.
Calculate the average velocity by adding the numbers together, and dividing by the number of shots (4, in this case).
Dial in your scope’s velocity setting, following the instruction manual that came with your scope.
Once this is done, your range compensation reticle markers should be calibrated to accurately shoot at the ranges advertised for each marker. You can test this by shooting at various ranges. If the accuracy is off, you should recheck your sight at 20 yards and recalibrate the velocity, again using the chronograph.
Keeping your scope sighted in
A properly sighted in scope should hold zero for quite some time, at least through a single hunting season. I’ve found that my scopes often hold zero through a couple of seasons, unless the scope is damaged or subjected to a fall. Regardless, always check your scope’s zero before the beginning of each season.

Pros
5 reticle aiming points, allowing shooting at variable ranges with ease.
Wide field of view while maintaining the image's high quality and resolution.
Long range clarity.
Water resistant and shockproof.
Cons
It fogs at colder temperatures, to the point of making it impractical to use.
Included rings are poor quality and make the scope difficult to mount and sight in, although as I mentioned, this is easily fixed by getting better quality ones and equipping them instead.
In case you have any questions about the Barnett 4x32 mm Multi-Reticle Crossbow Scope, this review will answer anything that may have crossed your mind. As a big fan of crossbows myself and an experienced, longtime hunter, I will do my best to cover all the features, pros and cons of this piece of equipment.
Starting off, let's talk a little about this scope. The dimensions, optics quality, magnification, how wide the field of view is: all are features that are critical to know before thinking of buying this. Let's take it one by one:
Composition
So what is this scope made of exactly? To put it precisely, this is a scope with a 5-point programmed multi-reticle crosshair system for rapid target acquisition at a variety of ranges and includes a set of 0.875-inch dovetail mounting rings. If you are a hardcore hunting fan like I am, you probably understand what every word means. But if you don't, keep reading.
Dimensions
Precisely, it's 8 inches long and 2 inches wide, which is pretty suitable in my opinion. I tried to fit it with different crossbows and it was pretty fine with nearly all of them. In addition, it's only 12.8 ounces heavy so you nearly don't feel any notable difference in the weight after putting it on.
Magnification
The scope guarantees 4X magnification power and although you may wonder if this could affect the image's resolution, the resolution remains quite high, giving you a very detailed picture. This is a pretty good pro in my opinion, as other scopes tend to raise the magnification power but neglect the resolution in the process.
Field of View
Although I like to be precise whenever I speak about something with numbers, unfortunately, Barnett didn't specify the exact dimensions for the field of view of this scope. However, I can estimate that it is about 340 at 100 yards, and if you wonder how wide that is, well, it's pretty wide given the price range of the item. Whether you need it to hunt small animals like rabbits or big ones like deer, the scope will prove helpful and easy to use in both cases.
Optics Quality
Multi-coated optics, high image quality and resistance to reflection; these features assure high optics quality that could be compared to the more expensive scopes. Sadly, all is not perfect. Although the scope is waterproof, it isn't the best to use in cold temperatures and the lens tend to fog and that makes seeing anything quite difficult.
This is sad because the rating here could have been 10/10 had the scope been fog-proof. As far as I know, nitrogen-charging a scope isn't that expensive and increasing the price by a few dollars while adding this feature in would have been a lot more convenient.
On a more positive note, the scope comes with clear, easy-to-follow instructions that help you with determining how your reticle lines should be for your setup and the good design makes shooting easy and possible at various dimensions starting from 25 yards and up to 50 yards. This could vary, of course, but the instructions make figuring this out quite easy.
Mounting and Sighting In
So far in my review, you can nearly point at no cons except that the scope fogs at cold temperatures. Well, this may be another con although it's easily fixable. The scope comes with its own rings to equip but my own advice is to throw these away and equip some better quality ones.
The ones that come with the scope are milled off-center and although it isn't much of a problem when mounting in, it's a huge bother when sighting. So the conclusion is: the scope is quite easy to mount and sight in given that you get some high-quality rings and equip them. Once you do that, you'll face no problems at all in that regards. In fact, the scope is pretty steady as I've tried hunting with it on for a long time and not once did I have to make any adjustments.

Light Gathering Capability
The scope is convenient and suitable to use even in poor light conditions so you don't have to worry about the time when hunting with this. However, it has no illumination features so seeing the reticles may become difficult, but in regards to the image quality and resolution, there's nothing to worry about.
Durability
The answer to this varies according to your weather conditions. The water and shock resistance make it quite durable unless you live somewhere where it's always cold (if you're wondering how cold, I am talking about under zero celsius temperatures,) or at least if it's like so during hunting season.
Okay, it's time to sum this up. I've talked about nearly everything to do with this scope, but I'll make a short summary and conclusion. If we want to list the pros and cons, we can say it would be.

For its price, the scope is high-quality and very decent but remains only practical if you need it for use in warm temperatures. However, if you hunt in colder temperatures, getting this scope would be a big no, as it fogs up quite easily and I would recommend looking for another product, one that would be at least fog-proof.
