Rifle Scope Product Details
Konus 7297 Rifle Scopes, Black
Finally, an affordable, precision, first focal plane riflescope with a reticle as unique as the scope itself. An illuminated, 1/2 mildot reticle affords precise shooting at long distance regardless of the time of day. The engraved “quick-peep” center crosshair removes any chance of the reticle covering your target. First focal plane means the target-to-reticle ratio is maintained throughout all magnifications without point of impact shift. The exterior, one-piece 30mm hardened aluminum tube provides superior resolution and brightness. The windage and elevation controls are resettable to zero, and incorporate a push/pull locking mechanism to avoid unwanted movement. The unique, built-in level bubble removes canting at long range and helps perfectly mount the scope atop your gun for improved accuracy. Developed to withstand the recoil from just about any caliber firearm, the F30 is perfect for every tactical, hunting, and target/bench rest shooter. The 6X-24X50 has a side parallax wheel from 10 yards to infinity. The 1/2 mildot reticle can be illuminated in traditional red, or an amazing blue. This is fantastic when shooting in dark conditions or into dark targets. The 1/10 mil adjustment coincides perfectly with the mildot reticle.

What You Need to Know About Glass
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s positioning can be adjusted to take into account separate natural factors like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes and optics have around eleven parts which are located inside and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has establishes where the reticle or crosshair is located in regard to the optic’s magnification. It simply implies the reticle is situated behind or in front of the magnifying lens of the optic. Picking out the most reliable sort of rifle optic is based upon what variety of hunting or shooting you intend on undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based on the extent of magnification being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the very same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are low
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who prefer a clearer optic sight picture without space used up by the enlarged FFP reticle
About Rifle Optic Magnification
The extent of scope zoom you need on your scope depends upon the kind of shooting you wish to do. Just about every style of rifle glass supplies some level of zoom. The volume of zoom a scope supplies is established by the size, thickness, and curves of the lens glass within the rifle scope. The zoom of the scope is the “power” of the glass. This denotes what the shooter is looking at through the scope is amplified times the power element of what can usually be seen by human eyes.
Info on Fixed Power Lens Rifle Optics
A single power rifle scope or optic comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not adjust since it is a set power scope.
Info on Adjustable Power Lens Glass
Variable power rifle scopes can be changed between magnification levels. It will note the magnification amount in a format such as 2-10×32. These numbers suggest the magnification of the scope can be changed between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power shift is accomplished using the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some recommended scope powers and the ranges where they could be successfully used. Always remember that high power scopes will not be as effective as lower powered glass due to the fact that increased magnification can be a negative thing in certain situations. The exact same concept applies to extended distances where the shooter needs adequate power to see precisely where to best aim the rifle at the target.
Lens Coating for Rifle Glass
All modern rifle optic and scope lenses are coated. There are various types and qualities of glass coverings. When considering high end rifle optics and scope setups, Lens finishing can be a significant component of defining the rifle’s capability. The lenses are one of the most crucial pieces of the scope considering that they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens surface and also assists with anti glare from excess direct sunlight and color recognition.
HD Versus ED Rifle Scope Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens finishes which use different techniques, aspects, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Optic Lens Single Finishing Versus Multi-Coating
Various optic lenses can even have different finishings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a covering applied to it so that it will be optimally usable in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has had several treatments applied to the surfaces of the glass. If a lens gets several treatments, it can establish that a company is taking numerous steps to combat various natural factors like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally does not necessarily mean the multi-coated lens is better than a single covered lens. Being “much better” depends upon the maker’s lens treatment solutions and the quality of glass used in constructing the rifle scope.
Hydrophobic Rifle Glass Lens Finishing
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic covering.
Glass Installation Choices
Mounting solutions for scopes can be found in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release versions which use throw levers which allow rifle shooters to rapidly mount and dismount the scopes.
Hex Key Glass Rings
Basic, clamp design mounting optic rings use hex head screws to install to the flattop design Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use double individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This kind of scope mount is exceptional for rifles which are in need of a long lasting, rock solid mount which will not change despite how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a faithful optics setup on a far away hunting or interdiction rifle that will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screws from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a comparable style mount, several scopes can often be switched in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These types of mounts are useful and practical for shooting platforms which are transferred between vehicles a lot, to take off the scope from the rifle for protection, or for sight systems which are adopted between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. Many scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Info on Rifle Scope Tube Gas Purging
Another part of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less altered by temp alterations and pressure distinctions from the outdoor environment which could potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
