Forum member Jacob spotted this simple, but effective set of scope ring inserts on the Brownells’ Website. With these inserts, you can use a scope with 1″-diameter body in 30mm rings. Non-marring, matte black Delrin sleeves surround the scope tube so it can fit larger-diameter rings. Each sleeve comes in two parts for easy installation around your scope tube. Ring Reducers are sold as front/rear kits. Cost is $14.99 for the 30mm to 1″ ring adapters, item 084-000-091.
Note: These Brownells units simply function as plastic bushings. Unlike Burris Signature Ring inserts, they do not allow you to “pre-load” windage or elevation. If your rings are misaligned, the Brownells Ring Reducers won’t correct that problem.
Starting June 1, 2015, Bullets.com will take over distribution of March Optics scopes in North America, replacing Kelbly’s. You will soon be able to order March scopes from Bullets.com, which now has exclusive March Scopes importing and distribution rights for the USA, Canada, Mexico, Central and South America. For a limited time, Bullets.com will offer March scopes at 15% below regular list pricing.
Bullets.com President Shiraz Balolia is excited about the March scope deal. He himself uses March scopes on his target rifles, and he knows their quality: “We are very fortunate to have been appointed to be the exclusive distributors for the American continent of a very high end scope line like March. I have been a user of March scopes almost since they were first offered. Many major matches have been won with them.”
Nightforce Optics has just launched its own YouTube channel. It’s worth a visit. You’ll find many informative videos worth watching, including Product Intro videos, Nightforce In Action clips, and the Torture Test video. On the Liked Videos Playlist, you can also watch related product reviews and field tests from Extreme Outer Limits, the 6.5 Guys, and AccurateShooter.com.
In the above video, a spokesman for Horus Vision explains how and why scopes can experience zero shift. First, just cleaning the gun can cause a small shift in point of impact. Second, when you re-tighten rings and ring bases, this can cause a change in zero. Horus recommends that you use a torque wrench to confirm that you maintain the same torque settings each time. The same goes for action screw tension — tensioning your action screws can shift the point of impact.
Other factors that can cause a change in zero:
Temperature
Dramatic ranges of temperature will change your zero, because the air density affects the velocity of the bullet. With increased temperature, there may be a higher velocity (depending on your powder).
Gun Handling and Body Position
You rifle’s point of impact will be affected by the way you hold the gun. A “hard hold” with firm grip and heavy cheek weld can give you a different POI than if you lightly address the gun. Even when shooting a benchrest gun, the amount of shoulder you put into the rifle can affect where it prints on paper.
Type of Rifle Support — Bench vs. Field
Whenever you change the type of rifle support you use, the point of impact can shift slightly. Moving from a bipod to a pedestal rest can cause a change. Similar, if you switch from a mechanical rest to sandbags, the gun can perform differently. That’s why, before a hunt, you should zero the gun with a set-up similar to what you would actually use in the field — such as a rucksack or shooting sticks.
Transportation of Firearms
Even if you don’t mishandle your weapon, it is possible that a shift of zero could occur during transport. We’ve seen zero settings change when a tight plastic gun case put a side load on the turrets. And in the field, if the turret knobs are not covered, they can rub against clothing, gear, storage bags, scabbard, etc. If the knobs turn, it will definitely move your reticle slightly and cause your point of impact to be off.
Forum member Roy Bertalotto did a real nice off-set scope installation on a bolt gun to help a sight-challenged shooter. Roy explains: “A friend of mine shoots left-handed and has lost the sight in his left eye. I built him a scope mount so he can still shoot left-handed, but now use his right eye.” Roy’s fabrication work is impressive and we praise his efforts to help a fellow shooter stay in the game.
Roy bolted a plate to the existing scope rail on the top centerline of the Rem 700 action. This plate extends a few inches to the right. On the outboard end of the plate, Roy fitted a second scope rail, aligned with the bore. Weaver-based rings are then clamped to the outboard (right side) auxiliary rail.
Be Careful of Canting Issues with Offset Scope Installations
We’re pleased to see that Roy developed a solution for a shooter with an optical disability, but we want to stress that this is a specialized installation that can create some problems with point of impact shift if the gun is not maintained perfectly level. With the amount of horizontal offset (between the scope’s optical axis and the bore axis) built into this rig, if the rifle is canted, point of impact can shift rather dramatically. For a southpaw who is willing to adapt his/her shooting style, it may be better, in the long run, to learn to shoot right-handed if his/her right eye is the only good eye. Likewise, if a right-handed shooter can only see well through his left eye, he may benefit from learning how to hold the stock and work the trigger with his left hand. The shooter could still work the bolt with his non-trigger hand. Changing from right-hand to left-hand shooting (or vice-versa) may require a stock swap if the stock is not ambidextrous.
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.

Schmidt & Bender revealed some impressive optics at SHOT Show. Perhaps the “star” of the S&B line-up was the 3-27x56mm PMII. This optic boasts the first-ever 9 times zoom range. Originally custom-designed to U.S. SOCOM specs, this impressive optic won a contract for use in SOCOM sniper platforms. S&B’s representative said this scope, when employed with steep-angled bases, may be used to engage targets at distances exceeding 2 kilometers.
Unrivaled Brightness — T96 Polar Offers 96% Total Light Transmission
Schmidt & Bender also unveiled its all-new 2.5-10x50mm Polar T96 scope, which S&B claims is “the brightest low-light hunting scope in the world” Designed for hunting, the new Polar boasts extremely high 96% light transmission levels, the most ever in a 10-power scope. In addition, transmission of “night-relevant wavelengths” has been improved dramatically, offering 5% more light in the evening than other hunting scopes. This means the scope will be brighter at dusk than other optics, effectively extending a hunter’s usable time in the field, allowing the hunter to use “the last light of the day.” S&B is considering expanding the T96 scope line to include 3-12X or 4-16X models.
Schmidt & Bender had scores of scopes on display, worth well over $100,000 in retail value.
Our friends Ed and Steve, aka the 6.5 Guys, were prolific last week in Las Vegas, visiting dozens of vendors at SHOT Show. Here are Ed and Steve’s video reports for Ashbury Precision Ordnance (APO), Vortex Optics, and Thunderbeast Arms. (If you’re thinking about buying a suppressor definitely check out the new Ultra series from Thunderbeast, featured in the third video below). You can see more SHOT Show videos by Ed and Steve at 6.5Guys.com.
Ashbury Precision Ordnance
Here Precision Rifle Series (PRS) Competitor Melissa Gilliland talks about the modular chassis systems offered by Ashbury Precision Ordnance (APO). With adjustable buttplate, cheekpiece, and grip, these systems can be adapted for a variety of shooting disciplines. APO even offers a modular chassis for Savage barreled actions. Melissa shoots a tricked-out 6.5 Creedmoor rig with a Titanium APO action.

Vortex Optics
Vortex continues to grab a larger share of the tactical and long-range hunting markets. This video features the Vortex Razor HD Gen II 4.5-27x56mm and 3-18x50mm scopes. These Gen II Razors feature apochromatic objective lenses, rugged 34mm single-piece aluminum main tubes, and versatile 6X zoom range. Both MOA-based and Milrad-based reticles are offered. Vortex scopes have large, user-friendly controls, and a good feature set for the price.
Thunder Beast Arms
Thunder Beast Arms’s suppressors, built by shooters for shooters, are tough yet light. Thunder Beast developed a strong following for its titanium cans that offered excellent performance with light weight. In this video, Thunder Beast unveils its new “Ultra” series of suppressors. Compared to Thunder Beast’s previous CB-series suppressors (of like size), these Ultras are 4 to 5 ounces lighter, yet provide 4 to 5 decibels of additional noise reduction. That represents a major gain in suppressor performance.
With the price of some premium scopes approaching $3000.00 (and beyond), it’s more important than ever to provide extra protection for your expensive optics. ScopeCoat produces covers that shield scopes with a layer of neoprene rubber (wetsuit material) sandwiched between nylon. In addition to its basic covers, sold in a variety of sizes and colors, ScopeCoat has a line of heavy-duty 6mm products that provide added security.
Triple-Thickness XP-6 Model for Added Protection
The XP-6 Flak Jacket™ is specifically designed for extra protection and special applications. The 6mm-thick layer of neoprene is three times thicker than the standard ScopeCoat. XP-6 Flak Jackets are designed for tall turrets, with sizes that accommodate either two or three adjustment knobs (for both side-focus and front-focus parallax models). To shield an expensive NightForce, March, or Schmidt & Bender scope, this a good choice. XP-6 covers come in black color only, and are available for both rifle-scopes and spotting scopes.
The heavily padded XP-6 Flak Jacket is also offered in a Zippered version, shown at right. This is designed for removable optics that need protection when in storage. The full-length, zippered closure goes on quick-and-easy and provides more complete protection against dust, shock, and moisture. MSRP is $30.00.
Special Covers for Binos and Red-Dots
ScopeCoat offers many specialized products, including oversize covers for spotting scopes, protective “Bino-Bibs” for binoculars, rangefinder covers, even sleeves for small pistol scopes and red-dot optics. There are also custom-designed covers for the popular Eotech and Trijicon tactical optics. Watch the Shooting USA video below to see some of ScopeCoat’s latest specialty covers.
