Rifle Optic Information
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target over a range. They do this through magnification by making use of a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of different natural elements like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. Many modern rifle scopes and optics have around eleven parts which are arranged within and externally on the optic. These parts include the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
About Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle glass is based on what type of shooting you plan on doing.
First Focal Plane Optics
First focal plane optics (FFP) feature the reticle before the magnification lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. For example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are low
- Experienced shooters who recognize their target “hold over” and “lead” ratios for their long gun
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the magnifying lens. This induces the reticle to remain at the exact same overall size in relation to the volume of zoom being used. The result is that the reticle measurements change based upon the magnification employed to shoot over greater ranges due to the fact that the markings represent various increments which differ with the zoom level. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular sorts of optics are convenient for:
- Long distance styles of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter ranges and proximities
- Shooters who choose a clearer optic picture without space used up by the larger sized FFP reticle
Details on Scope Magnification
The measure of scope zoom you need on your glass depends upon the type of shooting you plan to do. Practically every kind of rifle glass delivers some amount of zoom. The quantity of magnification a scope gives is identified by the diameter, thickness, and curves of the lens glass within the rifle optic. The zoom of the optic is the “power” of the opic. This suggests what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Single Power Lens Rifle Scopes
A single power rifle optic comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change since it is set from the factory.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes can be changed between magnification power levels. It will list the magnification degree in a format such as 2-10×32. These numbers mean the zoom of the scope can be set between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power modification is accomplished by working with the power ring component of the scope near the rear of the scope by the eye bell.
The Power and Range of Scopes
Here are some recommended scope power levels and the distances where they could be successfully used. Bear in mind that high magnification scopes and optics will not be as practical as lower powered optics since increased magnification can be a bad thing. The very same idea applies to extended distances where the shooter needs to have adequate power to see precisely where to properly aim the rifle.
Info on Rifle Optic Lens Coverings
All modern-day rifle optic and scope lenses are layered. Lens covering can be a vital element of a rifle system when looking at high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coatings which use various processes, aspects, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different scope lenses can also have various finishings applied to them. All lenses generally have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering 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 producer and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has had numerous treatments applied to them. If a lens gets several treatments, it can prove that a manufacturer is taking numerous steps to fight various environmental factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also doesn’t necessarily suggest the multi-coated lens will perform better than a single coated lens. Being “much better” is dependent on the maker’s lens treatment techniques and the quality of materials used in developing the rifle optic.
Anti-water Lens Coverings
Water on an optic’s lens does not support maintaining a clear sight picture through an optic whatsoever. Many top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner glass lens so the water particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Scope Mounting Options
Installing options for scopes come in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually are made in quick release versions which use toss levers which enable rifle operators to rapidly mount and dismount the glass.
Hex Key Rifle Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is excellent for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. A wide range of scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect 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 types of mounts are useful and handy for rifles which are carried a lot, to take off the scope from the rifle for protection, or for sight systems which are used in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
Info Around Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. Many scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another component of avoiding the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the optic is less affected by temperature alterations and pressure variations from the outside environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
