Using the Scope
Reticle Focus
To adjust the reticle focus:
1. Set the magnification to the highest setting.
2. Point the scope at a blank white wall or up at the sky.
3. Glance through the scope. If the reticle is not in focus, look away and make an adjustment to the eyepiece. Repeat this process until the reticle is in sharp focus.
Magnification
The mag ring indicates both the power of magnification and the FPS for the crossbow. Yardage marks on the reticle will be accurate when setting the FPS on the magnification ring to your crossbow’s FPS setting. To adjust the magnification:
1. Rotate the magnification ring to the desired magnification or FPS.
Turrets
This crossbow scope features precision, finger-adjustable elevation and windage turrets with tactile clicks. To make adjustments:
1. Remove the elevation and/or windage turret cap(s).
2. Turn the turret in the direction you wish the arrow’s point of impact to go: up/down or left/right.
3. Replace the cap(s) when done.
Illumination
To activate the illumination, rotate the adjustment dial in either direction. This illumination dial allows for continuous adjustment between levels of brightness intensity. An off click between each color allows you to turn the illumination off and return to either color quickly.

Rifle Glass Facts
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification using a set of lenses within the scope. The scope’s positioning can be adapted for consideration of various ecological aspects like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have around 11 parts which are arranged inside and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has establishes where the reticle or crosshair is located in connection with the optic’s zoom. It simply suggests the reticle is situated behind or ahead of the magnification lens of the scope. Picking the most desired style of rifle scope is based upon what style of hunting or shooting you intend on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. For example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and “lead” ratios for their long guns
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to stay at the exact same scale in connection with the level of magnification being used. The effect is that the reticle dimensions change based on the zoom applied to shoot over greater distances given that the markings represent distinct increments which fluctuate with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular sorts of scopes work for:
- Long distance styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who prefer a clearer optic sight picture with less area taken up by the enlarged FFP reticle
Magnification for Glass
The level of scope magnification you need on your optic depends upon the type of shooting you plan to do. Virtually every style of rifle optic supplies some amount of zoom. The level of magnification a scope offers is determined by the dimension, density, and curves of the lenses inside of the rifle optic. The magnifying level of the scope is the “power” of the opic. This implies what the shooter is looking at through the scope is magnified times the power aspect of what can generally be seen by human eyes.
About Fixed Single Power Lens Optics
A single power rifle optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is fixed.
Variable Power Lens Optic Info
Variable power rifle scopes can be modified between magnified settings. The power modification is achieved using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Glass
Here are some suggested scope powers and the ranges where they could be efficiently used. Highly magnified optics will not be as effective as lower magnification level rifle scope glass considering too much zoom can be a bad thing. The same goes for longer distances where the shooter needs sufficient power to see precisely where to best aim the rifle at the target.
Info on Glass Lens Coverings
All cutting-edge rifle optic and scope lenses are layered. Lens finishing is a crucial element of a rifle system when buying high end rifle optics and scope systems.
HD Versus ED Optic Lens Coatings
Some scope producers likewise use “HD” or high-definition lens finishes which use various processes, chemicals, polarizations, and elements to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finish Versus Multi-Coating
Different optic lenses can also have various finishings applied to them. All lenses typically have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in numerous kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Finish for Optics
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic finish.
Scope Mounting Options
Mounting approaches for scopes can be found in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release versions which use toss levers which allow rifle shooters to rapidly install and remove the glass.
Hex Key Optic Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope install is wonderful for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts come in handy for shooting platforms which are transferred a lot, to take off the scope glass from the rifle for protection, or for scopes which are employed between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Details on Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Optic Gas Purging
Another part of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the glass is less influenced by temperature level changes and pressure differences from the outside environment which might potentially permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
