Scope Can’t Error Explained
A cant error occurs when the rifle bore axis along with the axis of the scope is not aligned in a vertical plane. This becomes one of the many factors behind why a shooter fails to hit the target with accuracy while taking part in precision shooting.
When the tip of the gun barrel is raised to compensate for gravity while shooting at a target, the gun barrel does not remain parallel to the straight line of sight, from the eye to the acquired target. As a result, the bullet will hit the target a little to the side or lower than where it was actually aimed at. This is a classic shooting error, and how distant is a shot from the desired impact point is directly proportional to the distance of the target.
A simple way to eliminate scope cant error is by making sure the scope’s horizontally positioned crosshair is leveled, or rather horizontal. Scope levels are also ideal tools to eliminate the cant error. Many shooters use the horizon as a way to check the cant error. A problem with this method is that, unless the horizon is flat like when a large water body is involved, the horizon is uneven and cant error remains. Slopes are one of the most misleading terrains one could pick as a way to check cant error.
The most effective way to resolve the issue of cant error is a good scope level. A good scope bubble level will be able to ensure that the rifle is always held in the same manner as when it was sighted at the range. Some of the most popular brands producing scope bubble levels are Vortex Optics, Flat-line Ops, and Holland’s. These bubble levels show exactly how much misalignment is there between one’s scope and rifle.
Things to Consider Before Buying Scope Bubble
Size of the riflescope
Before buying an anti-cant device, make sure of its compatibility with the sizing of the tube. Keep in mind, the mounting of an anti-cant device has to be extremely sturdy so as to avoid any chances of the device falling off. Scope levels that can be attached to the scope tube itself are often the better choice.
Since they are available in alternative sizes depending upon the brand you choose, the place where you attach your anti-cant device helps you determine the width of the scope level to be purchased.
Accuracy
This is the most important feature to look for while purchasing a scope bubble level.
Mostly in tactical settings, shooters miss out on easy shots without discovering the reason. When the target is aimed at with a leveled reticle, the shots are more accurate.
Since this device is used to avoid errors while aiming, make sure that the scope bubble level gives readings as accurate as possible. Long-range shots are also made more precise this way.
Cant level
While shooting on an uneven range, it might be impossible to see how much of the cant error is present. Nonetheless, on a flat range, a well-cared device will show how out of alignment the rifle and the scope are.
A right level of cant will give the shooter an edge while aiming. Failing to level cant the right way will result in poor aiming and missed targets.
Durability
For sure a product that is durable enough to serve for a long time and not only for single-use is going to rank much higher in anybody’s book. Never compromise on the quality of materials used in making the product, this helps assure they are long-lasting.
Since it will be used with various firearms, recoils can never be avoided. Make sure that the chosen scope bubble level has something that will enable them to endure it. Also, make sure it is not easily detachable from the firearm, or the vial will randomly fall off during shooting.
Brand
Choosing a product from a well-known brand has its perks. Apart from the excellent product quality, well-established brands offer customer support in case the scope bubble level shows problems in the future.
Also, remember to pick a brand that provides their services near you. This way availing of their services when needed will not become a hassle.
Price
No matter what, the price of the product is one of the crucial buying factors and the same principle stands for the scope bubble level. Remember, a high-priced scope bubble level is not superior to the other anti-cant devices.
Even though it may lack additional features, a budget scope bubble level will get the job done. They may also have unique features to offer.
Mounting
The way the scope bubble level is attached to the scope makes a huge difference.
- Scope Mounted: The majority of anti-cant level devices clamp onto the tube section of the scope. They can be placed on either the left or right area depending on individual preferences. This is generally chosen by long-distance shooters or varmint killers.
- Picatinny Rail Mounted: It is the hinge mechanism that assists these anti-cant devices to swing open when the rifle needs to be used, or fold back in terms of keeping the weapon aside. Never forget, if you have an AR or any tactical rifle, this is a great choice.
FAQ’s
Ans: If the devices are chosen rightly to suit the rifle and the scope, then it never becomes a distraction. Bulky devices often come in the line of sight while taking aim, this is not ideal. Therefore, always pick a scope bubble level that matches your gear size.
Ans: Good quality scope bubble levels are built to withstand recoils. The devices like Vortex Optics riflescope bubble levels are strong enough to resist high recoils rounds. Looking for scope bubble levels with such relevant qualities is important before buying them.
Ans: Most of the anti-cant devices produced lately can be described as ambidextrous in nature. They can be used equally well by right-handed and left-handed shooters. Hence, left-handed shooting enthusiasts need not worry about the availability of suitable gear.
