Rifle Glass Details
Rifle scopes permit you to precisely align a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by using a set of lenses inside the scope. The scope’s alignment can be adapted to take into account many natural things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have about 11 parts which are located internally and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. See all eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the finest type of rifle glass is based around what type of shooting you plan to do.
Info on First Focal Plane Scopes
First focal plane optics (FFP) feature the reticle ahead of the zoom lens. This triggers the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who have an idea for their target “hold over” plus “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who choose a clearer optic sight picture without area used up by the larger size FFP reticle
Optic Magnification
The amount of magnification a scope provides is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass Info
A single power rifle optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change considering that it is a fixed power scope.
About Variable Power Lens Optics
Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power settings and the ranges where they may be effectively used. High power scopes will not be as efficient as lower powered scopes due to the fact that too much zoom can be a bad thing. The exact same idea applies to longer distances where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Lens Coating for Scopes
All top teir rifle optic lenses are layered. Lens finish can be a significant element of a rifle when buying high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different techniques, chemicals, aspects, and polarizations to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
About Single Finishing Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a finishing applied to it so that it will be optimally functional in numerous types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less helpful 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 also make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has multiple treatments applied to them. If a lens receives numerous treatments, it can prove that a producer is taking multiple steps to fight various natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also does not necessarily suggest the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the maker’s lens treatment technology and the quality of components used in creating the rifle optic.
Anti-water Lens Covering
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering.
Choices for Installing Rifle Glass on Firearms
Mounting options for scopes come in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also typically come in quick release versions which use throw levers which enable rifle shooters to quickly mount and dismount the scopes.
Rifle Glass Mounting Solutions with Hex Key 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is fine for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Numerous scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Info Around Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day of shooting and your costly optic by resulting in fogging and generating residue inside of the scope tube. A lot of scopes protect against wetness from going into the optical tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for standard use rifles, unless you anticipate taking your rifle on your motorboat and are concerned about the scope still performing if it goes over the side and you can still find the firearm.
Rifle Optic Gas Purging
Another component of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the glass is less altered by condition changes and pressure differences from the outside environment which could possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
