Today’s video showcase covers bore-sighting methods and technology. Bore-sighting the old-fashioned way — by looking down the bore of a rifle at a target — is not difficult. With a conventional bolt-action rifle, visual bore-sighting can be done quickly and easily. Rest your gun securely on bags, remove your bolt and set up a 50-yard target with a large bright orange or black center circle. Look through the back of the action and you should be able to sight down the bore with your own eyes just fine. There’s no need for expensive hardware. In fact it may be easier to bore-sight the “old-fashioned way” rather than try to see a laser in bright sunlight at 50 yards (or even 25).
However, with lever guns and semi-auto rifles, including the popular AR15, M1 Garand, and M1A, the design of the receiver may make it virtually impossible to sight down the bore with the naked eye. That’s where a modern laser bore-sighting device comes in handy. For those situations where a bore-sighting tool is needed, we recommend a laser bore-sighter that fits inside your chamber. An in-chamber laser device, as shown below, is handy and has less safety risk than a tool which fits in the end of the barrel.
How to Bore-Sight Your Rifle in Five Minutes
This video from Australia shows the basics of the bore-sighting process. First set up a target 50 yards (or closer) from your shooting station. Make sure the rifle is well-supported and stable. When the target is ideally centered in the BORE of the barrel, then adjust the reticle on your scope to center the crosshairs on the middle of the target. Then, after checking down-range, take a few test shots. Finally, move the target out to 100 yards and confirm your zero, as explained at the close of today’s article.
Vortex Shows How to Bore-Sight Rifles
This well-made, informative video from Vortex covers the basics of bore-sighting. Bore sighting your rifle is a simple way to establish an initial zero to get you on target faster and save you ammo at the range. Thankfully, it doesn’t take a ton of gear or ammunition to bore-sight a rifle effectively. Video host Jimmy from Vortex provides a handy, step-by-step guide in this 10-minute video.
Bore-Sighting Using a Barrel-Mounted Laser Bore-Sighter
If you wondered why a barrel-mounted laser bore-sighter was off-center? Or if you want to learn how to use one properly, this video shows how to safely and properly zero a scope using a barrel-mounted laser bore sight device. Another option is a small cartridge-sized laser that fits inside the chamber. These sell for under $25.00 and are convenient. There are safety advantages to in-chamber lasers.
Initial Bore-Sighting at Home (Before You Head to the Range)
This useful video shows how to bore-sight a rifle at home. This can save time (and money for ammo) when you do get to the range to confirm your scope’s zero. This home procedure works best if the target is well-illuminated while the rifle is in a shadowed area, creating the best contrast. Also make sure the rifle is on a steady support — such as a portable gun vise or sandbags front and rear.
Bore-Sighting with a Red Dot (Reflex) Sight
As with conventional scopes, if you have a red dot sight or reflex optic, you’ll need to bore-sight your rifle, then zero the optic. [Reflex sights use a reflex lens to project a dot or reticle onto the target, whereas red dot sights use a flat, reflective surface to display a red dot reticle.] In this video, retired Navy SEAL Mark Cochiolo demonstrates how to bore-sight then adjust a red dot. Bore sighting allows you to zero your red dot so that your shots hit near your intended point of impact.
Learn More about Bore-Sighting with Tools
To learn more about bore-sighting, you can view a detailed article on the Warne Scope Mounts website. This features through-the-barrel images and discussion of tools that fit in the chamber or barrel to project a laser beam down-range. Shown below are cartridge-sized projecting lasers that fit in a rifle’s chamber. These are available for a wide variety of cartridge/chamber sizes.
WARNING: If you use an in-barrel laser be sure to remove it BEFORE chambering a round. ANY obstruction in the barrel can cause serious injury or even death if you fire a round.
Bore Sight Grid Tool with Arbors
The Bushnell Bore Sight with Arbors is a bore-sighting tool that many gun stores and gunsmiths use. This device uses arbors but does not transmit a laser.
You attach the tool to the end of the barrel and align it with your scope. A grid is visible inside the bore-sighter. Look at that grid and then and align your scope’s reticle with the grid. This Bushnell unit ships with three expandable arbors in 22-270 caliber, 7mm-35 caliber, and 35-45 caliber.
How to Zero a Hunting Rifle Efficiently
Once you have bore-sighted your rifle to get “on target” successfully, then you want to zero your optic so that the shot falls exactly where you want it at your target distance, typically 100 yards. This Vortex video shows you how to quickly and efficiently sight-in and zero a hunting rifle before heading out into the field. This video explains a simple procedure that lets you get a solid zero in just three shots. Of course you probably want to fire a few more rounds to confirm your zero before you head off to your hunting grounds, but this will let you get on-target with a minimum amount of time and ammo expended. This helpful video now has 3.2 million views on YouTube!
Fouling Shots and Cold Bore Condition
If you recently cleaned your rifle, you may want to fire two or three fouling shots before you start this procedure. But keep in mind that you want to duplicate the typical cold bore conditions that you’ll experience during the hunt. If you set your zero after three fouling shots, then make sure the bore is in a similar condition when you actually go out hunting.

For many years, the Swarovski Optik website featured a blog with interesting technical articles. (Unfortunately some of these articles have been taken offline.) In the “On Target” series of blog stories, Swarovski provided a handy explanation of how optics systems work, with exploded diagrams of rifle scopes, spotting scopes, and binoculars. We’ve reproduced the key diagrams here. CLICK HERE for Swarovski On Target Archive.
Scope Terminology Focusing Lens
The focusing lens is an adjustable lens inside the optical system for focusing the image at different distances…. In the case of rifle scopes, apart from focusing, the focusing lens also facilitates parallax compensation.
Objective Lens
The objective lens is the optical system’s front lens group facing the object and operates like a converging lens. Its purpose is to display an image which, at the image plane, appears upside down, laterally transposed and reduced, and which is subsequently displayed correctly again by the reversal system.
Diopter Adjustment
For rifle scopes, the reticle can be focused using the diopter adjustment on the eyepiece, thereby correcting any visual impairment. [Editor’s Note: Movable eyepiece diopter adjustment is not offered on all rifle scopes. It is a useful feature on Swarovski and other premium scopes. This allows shooters who need eyeglasses to get a sharply focus image even without wearing corrective lenses. Of course shooters should always wear ANSI-certified eye protection. With the diopter, folks who need correction can use inexpensive, non-Rx safety eyewear instead of expensive prescription safety glasses.]
Reversal System
The purpose of the reversal system is to reverse the image by means of prisms in binoculars and telescopes, and lenses in rifle scopes….The lens reversal system is needed in rifle scopes to control the variable magnification and move the exit pupil[.]

If you’re looking for a state-of-the-art scope with a 34mm main tube, consider the new Foundation Series™ riflescopes from U.S. Optics. There are four new models, three zooms (1.8-10x42mm, 3.2-17x50mm, 5-25x52mm) plus a 10X fixed power. These look impressive. Check out the features of the FDN 25X 5-25x52mm ($3449) below. There are so many options! Chose among 11 different reticle types, and three illumination colors (Red, Blue, Green). Get a black Anodized finish or order any one of 8 Cerakote colors. For Elevation adjustment, choose a 1/10 MIL knob or 6.5 Creedmoor, or .308 Win BDC knobs. The Rapid Focus Eyepiece is even available with optional internal level.
This all represents serious optics technology. But you’ll pay for it. MSRP on the FDN 25X starts at $3449.00.
The Foundation Series is machined from aircraft-grade 6061-T6 aluminum and features a low profile ER3K elevation knob with a Zero Stop, capped US#1 windage knob, adjustable integrated parallax and illumination knob, rapid adjustable 180° magnification throw, and customizable options.
Now this is smart — ZEISS has just introduced a series of precision scope rings with integral bubble levels. These new ZEISS Ultralight 1913 Mil-Spec Rings for Picatinny Rails are beautifully made, making them a smart choice for mounting all brands of quality riflescopes. The rings are currently offered in 30mm diameter (low, med, high) and 36mm diameter (med, high), with 34mm versions coming out in the very near future.
We like the craftsmanship on these Precision Rings — they are “micro-radiused” on the machined leading edges to ensure a non-marring design. That special design feature helps prevent annoying marks on your expensive scope. Along with the built-in anti-cant levels, these rings feature an integral bottom recoil lug. That helps ensure the rings align perfectly and hold securely even with the high recoil forces generated by big caliber, magnum rifles.
Though these Precision Rings are very strong, they are also relatively light-weight. Crafted from Mil-Spec 7075-T6 aluminum (Type III) these rings weigh just 4.4 ounces with screws for a 30mm low set. For durability, ZEISS UltraLight Rings feature a 30-micron hard, matte black, anodized finish. The ring sets ship with a nice hard case, which includes both T15 and T25 Torx driver bits. The Zeiss Ultralight 30mm Rings cost $179.99 while the larger-diameter 36mm rings cost $199.99
NOTE: These rings are designed for correct, Mil-Spec Picatinny rails (aka MIL-STD-1913 rail or STANAG 2324 rail). Some lower-cost “Weaver-type” rails may not be ideal. ZEISS states: “For optimum performance and flawless mounting, we strongly advise that you mount [these rings] on a high-quality 1913 Mil-Std specification rail[.]”

When it comes to long-range optics, some folks can’t have too much magnification. At 500 yards and beyond, when the air’s misty or the mirage is thick, you can’t always use extreme magnification. But, when the conditions are excellent, it’s nice to have 50X magnification (or more) on tap. You can always “crank it back down”.
Higher magnification (when conditions are good), can help you see your bullet holes at long range, and that makes it easier to judge your hold-offs and keep your group centered.
In addition, there’s no doubt that high magnification lets you aim more precisely, no matter what the distance. Even at 100 and 200 yards, short-range benchresters are using 40X, 50X, and even 60X power scopes. This allows you to position your cross-hairs with extreme precision — something you need when you’re trying to put multiple shots through the same hole.
Raising the Optics Bar
How much power is usable? A few years back, folks said you can’t use more than 45X or so at long range. Well, as modern optics have evolved, now guys are buying scopes with even more magnification — way more. There are practical limits of course — with a 56 to 60mm front objective, the exit pupil of a 60X or higher-power scope will be very tiny, making head orientation ultra-critical. Any many scopes get darker as you bump up the magnification.
Despite the exit pupil and brightness issues, shooters are demanding “more power” these days and the scope manufacturers are providing new products with ever-greater magnification levels. Right now, the most powerful conventional riflescope you can buy is the March X-Series 8-80x56mm scope. Featuring a 34mm main tube and 56mm objective lens, this offers a true 10-times zoom ratio and up to 80X magnification. This scope has minimal distortion thanks to high-quality ED lenses designed in-house by Deon Optical, which also machines the main tube from one solid piece of billet aluminum.

To demonstrate the capabilities of high-magnification March scopes, Aussie Stuart Elliot has created a cool through-the-lens video with the March 8-80x56mm scope set at 80-power (See 0:30 timeline). Along with being one of Australia’s top benchrest shooters, Stuart runs BRT Shooters Supply, dealer for March Scopes in Australia. In the video below you can see the March 8-80X focused on a target at 1000 yards (910m). For best resolution, watch this video in fullscreen, 720p mode.

Review by James Mock
If you were charged with building a scope for F-Class or long range Benchrest, what features would you want? Vortex asked that question, received feedback from many competitors, and then set out to build a new high-magnification, zoom comp scope that would set a new “performance for price” standard.
The new Vortex Golden Eagle has features that this shooter really appreciates. It has a power range of 15x to 60x with a 52mm objective lens. Vortex has attempted to keep the weight as low as possible and the cost reasonable. My initial impression is that Vortex spared no expense in developing this scope. The “street price” for this premium scope is a reasonable $1499.00. Plus it has Unconditional Lifetime Warranty. Given its features, performance, and price, I believe that this scope will sell very well.
Premium HD, extra-low dispersion glass
APO (apochromatic) objective lens system with index-matched lenses
XRP multi-coated lenses for max light transmission
ArmorTek extra-hard lens coating to protect lens from dust, dirt, and smudges
Fogproof and Waterproof (Argon gas purged)
Specifications
Field of View at 100 yards: 6.3 feet at 15X; 1.7 feet at 60X
Main Tube: One-piece 30mm
Length: 16.1 inches; Weight is 29.7 ounces
Objective Lens: 52mm
Eye Relief: 3.9 inches
Reticles: SCR-1 FCH; ECR-1 MOA
Testing the Golden Eagle
I recently tested a Golden Eagle with the ECR-1 reticle. On this model the Hash Marks subtend 1 MOA at 40X. There is also a fine crosshair reticle (SCR-1) available. Initial tests with the scope were done on June 28th and I was very impressed with what I saw. With a new scope I always shoot the square (box test) to test tracking and amount of movement. I shot the square today after shooting a 5-shot group at 250 yards (my longest available distance). Below is a picture of the box test target that I shot. Yes, shot #5 went through the exact same hole as shot #1.
Below is the 250-yard target I shot before doing the box test. To get to the 100-yard target, I clicked down 14 clicks (1/8th MOA) and the scope was spot on. It is really a pleasure to use instruments that do exactly what they are supposed to do. With the Louisiana mirage, I shot this orange/white target at 40X instead of the maximum 60X. I did not have any problem seeing the 6mm bullet holes at 40X. The optics in this scope are to my old eyes are as good as any that I have used (regardless of price).
Competition Test Success — Golden Eagle Delivers a Win
My next use of this scope was at our monthly 600-yard match on July 15th. It was a typical mid-July day in north Louisiana — very hot and humid with light switching winds. The mirage was terrible, but I managed to squeak out a victory with a 188/5X score out of 200/20X possible. I shot the Golden Eagle at 40X all day and it performed perfectly. No one could see bullet holes today, even with the high powered premium spotting scopes. This is a quality scope and it may be a “lucky” scope in that I did not expect a win with a 6mm Dasher barrel with 2500 or more rounds through it.
Point of Aim Test with Hood Scope Checker
I also tested the Golden Eagle for holding Point of Aim (POA). For this procedure, I used the Hood scope checker (loaned to me by Bart Sauter). To use this, one mounts two scopes side by side. Ideally one scope has proven its ability to hold POA. Here I used a Valdada 36X BR model as my control scope. It has proven over an 8-year period of time to hold its point of aim. I mounted these scopes on my BAT/Leonard 6mm PPC and adjusted each to the same point on the target.
As one can see in the above picture, these are big scopes. After the first shot, I noticed that the reticle dot on the Vortex seemed to be about 1/8th MOA to the right of its original position. I stopped to check for ring slippage (which I had experienced in prior tests). There was no apparent slippage, so I checked the parallax and found that there was some parallax correction needed. This was probably the source of the apparent shift in point of aim, but I cannot be sure of that. I fired three more shots (checking after each) and found no shift.
After testing for POA shift, I fired the remaining rounds using different aiming points. I fired 5 rounds (upper left) using the Vortex and 3 rounds to the right of those using the Valdada scope.
CONCLUSION — A Very Fine Optic at a Reasonable Price
While testing this Vortex Golden Eagle scope, I developed a real fondness for it. I appreciate its great optics, eye relief and crispness of adjustments. If I thought that this scope did not hold POA, I would use my old Valdada in the 600-yard matches in which I participate. Further testing has shown no tendency to shift point of aim.
If I am allowed to keep this scope until the fall, I am sure that I will be able to see 6mm bullet holes in the white at 600 yards. Seeing those 6mm holes is very difficult, but that is my dream for a premium high-powered scope. During the summer months in north Louisiana, the air is much too “dirty” to spot small holes at 600 yards. By October, there should be some conditions in which one can use the premium optics to see bullet holes in the white at 600.
In summary, let me say that this scope has become one of my all-time favorites because of its bright, clear images and its great reliability. If you are looking for a great long-range scope that is reasonable in cost, try the Golden Eagle from Vortex.– James Mock

Editor’s comment: The new lens technology described here is a big deal. The “flexible” polymer lens is nothing short of revolutionary — there’s never been anything like it on a riflescope (though our own human eyes have flexible lenses). In the world of optics, this is as noteworthy a development as the touch-screen was for personal computing. Flexible, “adaptive” lenses can potentially be employed for a wide variety of products, from cameras to spotting scopes. Think about the benefits of “instantaneous zoom” for security cameras.
Sandia’s RAZAR Scope Features Flexible Lenses That Can Change Focal Length Instantly
Sandia National Laboratories has developed a truly game-changing piece of optical technology at the direct request of the Department of Defense: the RAZAR (Rapid Adaptive Zoom for Assault Rifles). Fundamentally different than every other riflescope ever made, the RAZAR represents a revolution in lens design and function. Until now, all riflescopes used a set of rigid, hard lenses (usually glass). The new RAZAR utilizes an advanced set of flexible polymer lenses that allow the user to toggle between high and low magnification with the press of a button. The RAZAR can literally zoom in and out in the blink of an eye (250 milliseconds).
The RAZAR works in conjunction with a tactical-style optic, such the Leupold HAMR (top photo). This tandem (two-part) sighting system combines the conventional scope’s eyepiece and illuminated reticle with the RAZAR’s ultra-fast zooming capability. Unlike traditional eyepiece (ocular) magnifiers, the RAZAR sits in front of the primary optic.
See RAZAR Demonstrated in Sandia Labs Video
Game-Changing Technology
The RAZAR’s instant, push-button zoom capability gives soldiers the ability to change field of view and magnification without re-positioning their grip on the rifle, unlike traditional variable-power riflescopes. This capability can be invaluable to a soldier in combat.
Michael Squire, a former SFC with Special Operations Research Support Element, said the ability to zoom between near and far targets within seconds, without taking his hand off the weapon, is “game-changing.” Squire added: “The difference that can make, especially with somebody shooting back, could mean life or death…”
The secret to the RAZAR’s high performance lies within the development of the advanced technologies within the scope. A hermetically sealed, flexible polymer lens core encapsulates a proprietary polymer liquid, and this core then works in tandem with glass lenses to form the basis of the optical design.
Rapid changes in magnification are accomplished via a piezoelectric motor that changes the curvature of the lenses, achieving the correct positioning within 250 milliseconds within an accuracy level of 100 nanometers. When zooming, these electronically-controlled actuators act much like the tiny muscles that allow the human eye to change focus from near to far. Human eyes have flexible lenses controlled with muscles*. The RAZAR has flexible lenses controlled by tiny electric motors.
It’s important to highlight the reliability that Sandia was able to build into the RAZAR. The system requires very little mechanical power to operate, and can undergo up to 10,000 zoom actuations on a single set of two standard AA batteries. The ultrasonic motor draws no power unless it’s being used to bend the soft lenses, which makes the RAZAR very reliable. If the batteries do go flat, the RAZAR remains fully usable — the system simply stays at the last magnification level until the batteries are replaced.
Sandia’s RAZAR design provides a large, clear viewing aperture, without sacrificing any of the optical quality found in traditional riflescopes. The RAZAR is also shock-proof, vibration-proof and capable of operating in a very wide temperature range.
The Future of “Instant Zoom” Adaptive Lenses
Sandia Labs is developing other specialty lenses in the near-infrared, short wave-infrared and mid-wave infrared spectrum, primarily for DOD use. However, Sandia has suggested that its flexible polymer-lens technology could be adapted for other imaging applications where rapid zoom is needed, such as binoculars, spotting scopes, and even security cameras. For more information, visit the Sandia Labs website.
*Changing the curvature of the human eye lens is carried out by the ciliary muscles surrounding the lens. They narrow the diameter of the ciliary body, relax the fibers of the suspensory ligament, and allow the lens to relax into a more convex shape. A more convex lens focuses divergent light rays onto the retina allowing for closer objects to be brought into focus.

At SHOT Show 2015, SIG Sauer showcased a host of new optics products. SIG’s new Electro-Optics division will market a complete line of riflescopes, battle sights, red dot/reflex sights, rangefinders, binoculars, and spotting scopes. For ALL the new Electro-Optics products, SIG will be offering a lifetime transferable warranty. That’s impressive. SIG’s new electro-optical offerings, which are named after radio alphabet words (such as “Bravo” and “Tango”), are revealed in this video:
The “Whiskey” riflescope series is marketed as a rugged, affordable optical solution for hunters. Designed for law enforcement and tactical shooters, the “Tango” series of riflescopes feature 6X zoom ratios and meet MILSPEC requirements. Shown below is the 3-18x44mm Tango.
The “Bravo” series of prismatic battle sights (illustration below) are pretty remarkable. An innovative new lens design provides an exceptionally wide field of view. SIG claims that Bravo battle sights offer a 50 percent greater field-of-view than similar battle sights.
The “Romeo” series of red dot sights are designed for tactical carbines. The miniature “Romeo1″ Reflex Sight is designed to be slide-mounted on a pistol, and SIG will offer several pistols with the Romeo1 pre-installed. For big game hunting or extreme long-range shooting, SIG developed the “Kilo” rangefinder series, the “Victor” spotting scope line and the “Zulu” binocular series. The “Kilo” rangefinder (bottom photo) can reach out to 1600 yards and features an auto-dimming display. It is about the same size as a Leica CRF, but it is easier to hold. There are molded, rubberized finger grooves on the top and the whole unit has a nice feel in the hand.
To learn more about other SIG Sauer products for 2015, visit the Shooter’s Log, presented by Cheaper than Dirt. For 2015, along with new handguns and rifles, SIG Sauer has rolled out a branded line of suppressors. SIG’s new cans should be popular with both tactical shooters and hunters (where suppressor use is allowed).

These scopes all include Leica’s Lifetime Warranty. According to EuroOptic: “Quantities vary and there will not be any more once they are gone”.
Leica ER Rifle Scopes are rugged, bright, and precise. Each Leica ER Rifle Scope is designed for field use, with a long tube for easy mounting and eye relief to spare – perfect for large caliber hunting rifles. Choose from the Leica ER 2.5-10×42, an all around scope with a wide field of view for quick acquisition, or the Leica ER 3.5-14×42, a higher magnification scope with an optional ASV elevation turret.
When it comes to long-range optics, some folks can’t have too much magnification. At 500 yards and beyond, when the air’s misty or the mirage is thick, you can’t always use extreme magnification. But, when the conditions are excellent, it’s nice to have 50X magnification (or more) on tap. You can always “crank it back down”.
