What You Need to Know About Glass

Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification using a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of different ecological considerations like wind and elevation decreases to make up for bullet drop.

The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes and optics have around eleven parts which are located inside and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets, focus rings, and other parts. Learn about the eleven parts of scopes.

Rifle Optic Styles

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has decides where the reticle or crosshair lies in connection with the scopes zoom. It literally implies the reticle is behind or ahead of the magnifying lens of the optic. Picking out the most ideal sort of rifle optic depends on what style of shooting or hunting you intend on undertaking.

About First Focal Plane Optics

First focal plane optics (FFP) include the reticle in front of the zoom lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards by using 5x “zoom”. These types of scopes work for:

  • Quick acquisition, long distance kinds of shooting
  • Shooting circumstances where computations are minor
  • Experienced shooters who know their aim point “hold over” plus “lead” relationships for their firearm
  • Shooters who don’t mind the reticle is enlarged and takes up more visual sight space than a SFP reticle

About Second Focal Plane Scopes

Second focal plane optics (SFP) come with the reticle behind 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.

  • Far away forms of shooting where shooters have more time to make ballistic estimations
  • Shooting where most of the shots happen within much shorter spaces and ranges
  • Shooters who select a clearer optic sight picture with less area used up by the bigger FFP reticle

Optic Magnification

The extent of scope zoom you need on your optic depends on the type of shooting you want to do. Practically every style of rifle optic delivers some level of magnification. The amount of zoom a scope delivers is determined by the dimension, thickness, and curvatures of the lenses within the rifle scope. The magnification level of the optic is the “power” of the scope. This denotes what the shooter is looking at through the scope is amplified times the power element of what can generally be seen by human eyes.

Fixed Single Power Lens Optic Details

A single power rifle scope uses a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust because it is a set power scope.

Variable Power Lens Scopes

Variable power rifle scopes can be tweaked between magnified levels. The power modification is performed by using the power ring part of the scope near the rear of the scope by the eye bell.

Rifle Scope Power Level and Range Correlation

Here are some suggested scope power settings and the distances where they can be successfully used. Consider that high magnification optics will not be as practical as lower powered glass since too much zoom can be a detractor. The very same idea applies to extended ranges where the shooter needs adequate power to see precisely where to best aim the rifle at the target.

Details on Lens Covering

All state-of-the-art rifle glass lenses are covered. Lens coating can be a significant aspect of a shooting system when looking at high end rifle optics and scope setups.

Info on Scope Lens Coatings – HD Versus ED

Some scope brands likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, elements, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.

Single Rifle Glass Lens Covering Versus Multi-Coating

Various optic lenses can even have various coatings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a coating placed on it so that it will be efficiently functional in many kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.

This lens treatment can safeguard the lens from scratches while decreasing glare and other less advantageous 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 producers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.

What to Know About Anti-water Coating

Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finish.

Scope Installation Options

Mounting options for scopes come in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally can be found in quick release variations which use toss levers which permit rifle shooters to quickly install and dismount the glass.

Hex Key Rifle Optic Rings

Standard, clamp style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These varieties of scope mounts use two separate rings to support the scope, and are normally made from 7075 T6 billet aluminum which are made for far away accuracy shooting. This type of scope mount is effective for rifle systems which need a resilient, rock solid mount which will not shift despite how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should have for a dedicated scope setup on a long distance hunting or interdiction firearm that will hardly ever need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used to prevent the hex screw threads from backing out after they are mounted firmly in place. An example of these rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD

Quick-Release Cantilever Rifle Glass Ring Mounts

These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be swapped out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping precision. These kinds of mounts come in convenient for shooting platforms which are transported a lot, to take off the glass from the rifle for protection, or for aiming systems which are used in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD

Details on Scope Tube Sealing and Gas Purging

Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. Many scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.

Details on Rifle Scope Tube Gas Purging

Another element of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less impacted by temp shifts and pressure differences from the outside environment which might potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
