In everyone’s inventory of rifles, we think there should be at least one basic utility rifle with decent iron sights. Tech-SIGHTS, a small company in Hartsville, South Carolina, produces high-quality, yet affordable front post/rear aperture sights that fit popular rifles such as the Ruger 10/22, Marlin 60, SKS, and the CZ 452. We were particularly impressed with the new CZ200 sight set for the CZ 452, a very popular .22LR and 17HMR training and varmint rifle.
For CZ 452s sold without iron sights, the $69.00 CZ200 sight package provides both an easily-adjustable rear aperture sight and a durable, hooded front sight. The Tech-SIGHTs, designed to fit the dovetail on top of the CZ receiver, can be quickly fitted to CZ 452s. Both the rear aperture and the front post (with protective ears) can be installed easily with no drilling or tapping. For CZ 452s equipped with factory iron sights, the Tech-SIGHTs will replace the rear tangent sight with a more precise micro-adjustable aperture sight, increasing sight radius by 6.5 inches.
Ruger Sight Set Features AR-style Front Sight
The Ruger 10/22 Tech-SIGHTs mount on the rear of the receiver utilizing the existing, tapped scopebase holes. Two versions are offered, the TSR100 with dual leaf (flip-adjust) apertures, and the TSR200 with a single (non-flip) aperture with enhanced elevation adjustment. Both TSR100 ($59.00) and TSR200 ($69.00) sight sets come with a front sight tower fitted with AR15-spec detent-adjustable post. This allows the shooter to swap in a variety of front sight posts made for ARs.

Experienced marksmen know they should keep their rifles level when shooting. But they may not understand exactly what happens if they allow their rifle to be canted (tilted left or right), even a few degrees. While the physics are complicated to explain, here’s what you need to know: if you cant your rifle to the left, your shots will impact to the left, and lower, than your point of aim. Likewise, if you cant your rifle to the right, your bullets will impact low and right.
Effects of Rifle Canting
The effects of rifle canting are explained in great detail on the Long Shot Products Ltd. website. There, you’ll find a technical discussion of the Physics of Rifle Canting, plus a page with Sample Targets shot with canted rifles.
Referring to the above illustration, the Long Shot Products article explains: “Notice how the trajectory of the vertical hold stays within the vertical plane, so when the projectile drops, it drops into the line of sight and down to the center of the target. The trajectory of the cant hold does not achieve the same height as the trajectory of the vertical hold and the projectile diverges from the line of sight, thereby missing the target.”
The Long-Shot article makes two other important points. First, cant error increases with distance, and second, cant-induced windage errors are worsened by mounting your scope high above the bore axis:
“This component of cant error becomes more significant at more distant targets due to the increased original included angle between the line of sight axis and the bore axis (more elevation compensation) at the vertical hold.”
“Use of large-diameter objective scopes, mounted high off the barrel, exacerbates the cant error problem. To keep the scope elevation knobs centered for maximum adjustment, precision shooters sometimes use elevation-compensated scope mounting rings or bases. Although this solves the adjustment problem, it greatly exaggerates cant error because the distance between the bore axis and the line of sight axis increases and the included angle between the sight axis and the bore is larger, producing more windage error when canting.”
Test Targets Reveal Cant Errors
The Long Shot Products Ltd. website also displays actual Test Targets showing the effects of canting error. These targets were shot with air rifles and rimfire rifles, but the same effects can and will occur with centerfire rifles. Shown below is a target shot at 50 yards with a Feinwerkbau .22LR match rifle using RWS Match ammo (1012 fps MV). As you can see, canting the rifle 20 degrees to the left produced a huge movement of the point of impact. The shots from the canted rifle impacted 1.81″ Left, and 0.6″ below the point of aim.

 Bushnell Outdoor Products has sued Leupold & Stevens for infringing on two Bushnell U.S. Patents covering the Bushnell Angle Range Compensation™ (ARC™) and Rain™ Mode laser rangefinder technology. The lawsuit was filed in the United States District Court for the District of Kansas on February 9, 2010 and alleges that Leupold is infringing on Bushnell U.S. Patent Nos. 5,926,259 and 7,658,031.
Angle Range Compensation is important for both rifle shooters and bow-hunters. When a shooter or archer takes a shot at an extreme up or down angle, there will be less drop than with a non-angled shot (given the same line of sight distance to target). By fitting an inclinometer to its rangefinders, Bushnell is able to plot the shot angle and display the “effective ballistic distance” to the target. You can then quickly calculate the hold-over you actually need.
 Bushnell pioneered the sportsman-oriented laser rangefinder, and Bushnell was selling rangefinders long before Leupold even entered the laser rangefinder market. Bushnell earned U.S. Patent No. 7,658,031 for its rangefinder technology that provides hold-over info for angled shots.
“Bushnell has invested an enormous amount of time and resources into developing our patented technology and we will vigorously enforce our rights against all infringers,” said Phil Gyori, Executive Vice President of Marketing at Bushnell Inc. “While we prefer to resolve disputes with our competitors without resorting to litigation, we felt we had no choice but to defend our intellectual property against Leupold’s infringement.”

 Many of our Forum members have reported that they have received their new Sightron SIII 10-50x60mm target scopes. These come with 1/8 MOA clicks and either a Fine Cross Hair reticle or FCH with target dot reticle. Currently the scopes do NOT include lens covers or screw-in sunshades.
In terms of optical performance, feedback so far has been very positive. Forum member Nat Lambeth recently received one of the new 10-50 Sightrons. He reports: “This scope, like the 8-32x56mm SIII, is much heavier-built than the first Sightron target scopes. It is very clear and sharp edge to edge. I shot 20, 5-shot groups with my [6BRX rifle with Savage Target action]… off a BR Rest and leather rear bag. The scope was cranked up to 50 power during my entire afternoon of shooting. The focus ring has a very short window of focus for a given distance. Otherwise clarity and light gathering was superb.”
The new scope is pretty large, measuring 16.9″ overall and weighing just under 29 ounces (without rings). Below you see the new Sightron 10-50x60mm next to a Nightforce NXS 12-42x56mm.
Some folks have been concerned about vertical clearance with the large 60mm front objective. The photo below shows the scope mounted on a Weaver-type rail with Burris Signature Zee “Extra-High” scope rings. As you can see, there is more than ample clearance. With most Weaver rails and barrel profiles you could probably go to the next lower Burris ring height — but we recommend you get the specs if you plan to use other types of rings.
The new Sightron 10-50x60mm scopes remin in stock at various vendors, but they are selling fast. MidwayUSA has them in stock today, priced at $994.99 (item 589261). Note: At this time, these scopes ship without scope caps or sunshade. Sightron hopes to have both caps and shades available by mid-summer.

The innovative Zeiss 2.5-10x50mm Diarange riflescope with built-in Laser Rangefinder is now on sale at EuroOptic.com for $2400.00. That’s an amazing price — the Zeiss Victory Diarange 2.5-10x50mm normally sells for $3949.00. This represents a $1549.00 savings over the regular price — almost 40% off. (EuroOptic.com also has the Zeiss Victory Diarange 3-12×56 T* demo models for $3,200.00 marked down from $3,999.00.)
 EuroOptic.com has about 40 units at this price. They are offered with either Rapid Z 800 or Rapid Z 600 reticles (both illuminated). The Zeiss Diarange is a unique products that combines a very high-grade riflescope with an integrated laser rangefinder. Measuring range for the laser is from 10-999 yards, with a measuring accuracy of ± 1 yard up to 600 yards and ± 0.5 % of reading at ranges beyond 600 yards. Ranging is fast and the scope offers outstanding low-light performance.
For a hunter looking to simplify his load-out, the Diarange allows you to sight your prey and range it with one device. You can keep both hands on the rifle at all times and you can keep your muzzle on target while you’re ranging. Eurooptics’ $2400.00 price is a lot of money, to be sure, but consider that the discounted Diarange gives you a high-end scope AND a rangefinder for about the same price as a Zeiss Diavari scope by itself.

Forum member Thomas Haugland (aka “Roe”) from Norway has created an excellent video comparing the features on four long-range scopes: Schmidt & Bender PMII 3-12x50mm, Schmidt & Bender PMII 12-50x56mm, Leupold MK IV, and Zeiss Diavari Victory 6-24x56mm. Thomas shows how the adjustments function, he records the available vertical elevation, and he takes apart the turrets to show how the weather seals work. While the Leupold MK IV has MOA clicks, the three Euro scopes tested by Thomas have mil-based or mil/cm adjustments. These mil-based clicks work well with first focal plane reticles that have mil or half-mil hash marks.
Thomas explains:
These films emphasize the shooter’s Point of View (POV) and ‘user friendliness’. ALL these scopes get the job done, but they have some similarities and differences in the details and your own personal preferences would decide what scope can be labeled ‘best’. The perfect scope doesn’t exist, you’ll have a compromise somewhere — be that economy, magnification, reticle, turret, optical quality, sturdiness…
In these films I’ve set the Schmidt & Bender PMII 3-12×50 as the benchmark for comparison. Not because it is ‘best’ (it isn’t!) but because S&B is one of the manufacturers which first recognized the needs of professional Long Range shooters and put together products [optimized to work well] in high stress environments. The features that are important are: First focal plane, MIL reticles and MIL turrets, plenty of adjustment and suitable magnification.
Note that S&B and Zeiss scopes are also available in the USA with MOA-based turrets and/or second focal plane (SFP) reticles, for those shooters who prefer the MOA system, and SFP. A first focal plane reticle is best for ranging, but a target shooter working at known distances will probably prefer a second focal plane reticle that doesn’t change in size with magnification.

 Nightforce Optics has enhanced their elevation adjustments in this year’s lineup of high-magnification Nightforce scopes. Now you can get DOUBLE the elevation travel with a SINGLE TURN of the elevation knob. For an NXS with 1/4-MOA clicks, this means you can get a full 20 MOA of elevation travel with a single turn of the knob.
Bravo, Nightforce — this simple enhancement can make a BIG difference in the field. With most “high-performance” calibers, 20 MOA will get you to 700 yards or beyond. This means that the varminter can zero at all likely hunting yardages within the same revolution of the turret. That makes life much simpler, and reduces the chance of being way off in your elevation. No more confusion about which revolution you’re on….
Likewise, a tactical shooter, moving from near to far targets and back again, can likely stay on the same revolution at most target yardages. Even if you shoot out to 1000 yards, you will be able to get all the way out to 1K within two complete revolutions. This upgrade — doubling the elevation travel in each turret revolution — gives Nightforce scopes practical performance (inside 700 yards) similar to much more expensive scopes fitted with a single-turn or double-turn elevation systems (such as the U.S. Optics EREK knob). The new high-speed adjustment system will be offered in Nightforce’s 15x, 22x, 32x, and 42x series of scopes. Anticipated delivery date for scopes with the high-speed adjustment is May, 2010.
What About Retro-fitting Older NF Scopes?
Nightforce plans to provide an upgrade path for existing Nightforce scopes “eventually, but not right away”. The upgrade would allow installation of the “high-speed adjustment” system on older NF scopes. We don’t have any more specifics. Nightforce has NOT revealed how much the high-speed conversion would cost or when it might be available for pre-2010 scopes.

On Media Day, just prior to SHOT Show 2010, our Assistant Editor Jason Baney headed straight to the biggest, baddest rifles he could find — a pair of serious-looking tactical rigs from Barrett Rifles. First off was the mighty semi-auto Barrett 82A1, chambered in .416 Barrett. a “beast of a cartridge” according to Jason. The .416 is a very powerful chambering, and you can see the recoil pushed Jason pretty hard. That’s serious energy — Jason’s a big boy, and the Barrett 82A1 weighs nearly 31 pounds. Want one? You may have to liquidate some investments. MSRP on the Barrett 82A1 is a whopping $9345.00.
Ninety-Eight Bravo in .338 Lapua Magnum
Next up was Barrett’s bolt-action model 98B (“Ninety-Eight Bravo”), chambered in .338 Lapua Magnum. At less than half the weight of the Barrett 82A1, the 98B was much easier to steer on the bench and the ergonomics were generally better according to Jason.
While recoil from the .338 Lapua Mag was stout, you can see in the video that the .338 LM kicked much less than the .416 Barrett, even in a gun with less than half the mass. The 98B gives you a good solid thump to the shoulder when firing. By contrast, the .416 Barrett in the 82A1 shakes your whole body. The 98B weighs 12.4-13.5 pounds (depending on configuration) and starts at $5039.99 without optics. Speaking of optics, the hooded display on top of the 98B is a Barrett Optical Ranging System (BORS). This $1500.00 gadget provides a digital read-out of your actual ballistics settings. It doesn’t control windage and elevation — that is still done manually with the scope knobs. BORS is an integrated electronic ballistic computer that mounts directly on the riflescope and couples to the elevation knob. Just turn the elevation knob until the LCD displays the target’s actual range (which must be pre-determined). The BORS’ three internal sensors automatically calculate a ballistic solution, compensating for up/down angle, temperature, and barometric pressure changes. It even tells you if the rifle is canted. It’s a handy device that eliminates the possibility that you loose track of your turret settings.
