Do you own a .22 LR rimfire pistol? Well now you can transform that handgun into a high-tech laser pistol, thanks to a new gadget from LaserLyte. The new .22 Caliber Laser Trainer works with nearly all .22 LR pistols (but not revolvers) with a striker or conventional firing pin. The battery-powered device emits a laser beam when you pull the trigger. The video below shows how it works.
We have to admit we liked the idea of this device so much, we ordered one from Amazon.com. The $83.22 retail price seems a little steep, but think of all the money you can save on .22 LR ammo (which is pretty darn hard to find these days anyway). We just wish there was a version for .22 LR revolvers.
WARNING: Before you use the LaserLyte .22 Caliber Trainer, check and double-check to ensure your pistol is UNLOADED!! That means NO ROUND IN THE CHAMBER! Pulling the trigger with the training device in the barrel (and a loaded round) could cause serious injury or death to yourself or someone downrange. As with any firearm, always make sure to follow all basic firearm safety rules! Additionally, never point the laser beam at another person — as the laser can cause eye injury.

Snow on the ground? Can’t go shooting outside? Here’s one way to have fun indoors while practicing your aiming skills. LaserLyte offers a set of three cans equipped with laser-activated “kickers” on the base. When a laser hits the can in the right spot the can topples over. The laser activates a solenoid that releases a spring-loaded plunger. To reset the cans, simply stand them up and depress the plunger.
Watch Laserlyte Plinker Training Cans:
The LaserLyte® Laser Plinking Can Set is sold in a three-pack with three 9V batteries included. One battery will tip the can over about 8,000 times. Watch the video to see how it works. This would be fun with kids (just follow safe practices with the laser beams).
To direct a laser at the plinking cans, you’ll need a firearm fitted with an in-barrel laser (instead of live ammo). Or, alternatively, you can use the blue plastic LaserLyte training pistol ($54.95). For actual handguns, you can use the universal LT-Pro laser module, or a caliber-specific unit that fits the chamber of your gun. The blue training pistol is designed to work with the LT-Pro universal module, as you can see in the video below, a field test by Gunsandammo.com. The testers noted that the cans may be sensitive to very bright light sources.

PrecisionRifleBlog.com recently published results from the most comprehensive field test of rangefinder binoculars ever conducted. It included virtually every product available in a variety of real-world scenarios, to see which had the best performance in the field in terms of both optical clarity and ranging capabilities. The results are based on over 10,000 data points collected from the field over 3 months of testing. Cal Zant, author of PrecisionRifleBlog.com, published a series of posts with exhaustive details about his optical and ranging tests and results, but we’ll hit the highlights here.
VOICE FILE: Click Button to Hear Cal Zant TALK about Rangefinder Binocular Test
Six of the models tested were binoculars, and the other two were monoculars. The Leupold monocular was included for reference, because many shooters have a 1,000-yard rangefinder similar to the RX-1000. The Vectronix Terrapin model was included as the control for ranging performance, because it is known to be an extremely accurate rangefinder (spoiler alert: it is). Cal provides a very detailed side-by-side spec comparison for these models in one of his posts.
Ranging Test Results
Each model was used to range 500+ times in a variety of scenarios from 25 to over 30,000 yards. The tests showed these models had similar performance at close and mid-range targets, but at 600 yards their performance started to diverge … so that is where most of the testing was focused.
The chart below summarizes the ranging performance found on the test targets in ideal conditions, which was from a sturdy tripod, at sunset, with 10+ mile visibility. The exact target shape and surroundings varied, but the targets were all approximately 2 MOA wide, highly reflective, and perpendicular to the rangefinder. Specifics on target dimensions, view from the ranging position, and target surroundings are given in the detailed ranging performance results post.
Vectronix is the leader of the rangefinder world, and that was proved once again in these tests. The new Leica Geovid HD-B wasn’t far behind them, with accurate ranging beyond 1 mile. The Zeiss Victory RF also had surgical precision off a tripod, although it had a reduced range compared to the Vectronix and Leica. The Bushnell Fusion 1 Mile also proved to be able to range targets out to their claimed max range of 1,760 yards.
PrecisionRifleBlog.com also tested the ranging performance of each model in bright lighting conditions, and offhand as well. The data from those tests also contained a few surprises. To determine how accurate each model really was, Cal Zant carefully analyzed the results from each model when aimed at precisely positioned, “known distance” targets. To see how those tests turned out, or learn more details about specific models, GO TO full results.
Optical Test Results
For the optics tests, Cal’s goal was to find an objective, data-driven approach to testing optical performance. What he came up with was placing eye exam charts from 600 to 1,400 yards with different size letters, and then recording what two different people could accurately read with each model. The data for each unit was summed into a single score so they could be ranked relative to how much detail the testers could make out. More specifics are provided regarding how the test was conducted and how scores were calculated in the optical performance results post. Here are the results from Cal’s data-driven approach:
The Leica Geovid HD-B edged out the other models for the top spot, with its completely new, Perger-Porro prism design. The original Leica Geovid HD, and Zeiss Victory RF also showed great optical clarity.
The Rest of the Story
Cal’s full series of posts is very informative. He’s done tons of analysis on the data, and summarizes it in several charts that provide a lot of insight. Cal is also in the process of publishing detailed reviews on each model, including notes he and the other testers compiled for each unit. They used them all — a lot, so they have a unique perspective on what’s good or bad about each. Find out more at the link below:
Could your next metal scope rings, trigger guard, or muzzle brake be crafted with a 3D printing process? It’s possible. In fact, a wide variety of metal parts (even a complete handgun) can be printed using the latest 3D Direct Metal Laser Sintering (DMLS) process. The way this works is as follows: powdered metal is heated by a laser, causing the metal particles to fuse and solidify. This is progressively repeated, in vertically-stacked layers, until the entire metal part is complete. It’s like building a metal layer cake with the shape/size of each thin layer defined by a precise laser beam. The laser is guided by computer-controlled servos following a CAD “blueprint”.
This video demonstrates how metal parts are 3D printed using the DMLS process. This technology is offered by Solid Concepts, a leading rapid prototyping and manufacturing services company.
The Solid Concepts 1911 — World’s First 3D-Printed Metal Firearm
Solid Concepts has manufactured the world’s first 3D-printed metal gun using a laser sintering process and powdered metals. The gun, a .45 acp 1911 clone, has already handled 50 rounds of successful live-fire testing. A 1911 design was chosen because the “blueprint” is public domain. The gun is composed of thirty-three, 17-4 Stainless Steel and Inconel 625 components, crafted through the DMLS process. Even the carbon fiber-filled hand grips are 3D printed, using a Selective Laser Sintered (SLS) process.
Except for the springs, all the parts of this 1911 handgun were printed using the metal laser sintering process. Yes even the highly-polished slide, the barrel, the frame, and the hammer were printed. There are no forgings, castings, or conventionally-machined parts. With the exception of springs, all 30+ components in this prototype pistol were printed using Direct Metal Laser Sintering (DMLS) technology. Watch the video for a glimpse into the future of gun-making:
World’s First 3D-Printed Metal Gun Test Firing
Solid Concepts believes that its fully-functional, 3D-printed 1911 handgun proves the viability of 3D printing for gun parts, even highly-stressed components. Kent Firestone, V.P. of Additive Manufacturing at Solid Concepts, states: “We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D metal printing. And we’re doing this legally. In fact, as far as we know, we’re the only 3D printing service provider with a Federal Firearms License (FFL). Now, if a qualifying customer needs a unique gun part in five days, we can deliver.”
Will we see complete 3D-printed metal guns on the market soon? That’s unlikely. It’s still more economical to produce complete guns the old-fashioned way. However, we may see 3D printing used for rapid prototyping. In addition, 3D metal printing has advantages for hard-to-machine parts with complex geometries. Solid Concepts reports that its 3D printed metal has fewer porosity issues than an investment cast part and better complexities than a machined part. It will be interesting to see what unfolds in the years ahead.

Scientists at the Oak Ridge National Laboratory (ORNL) have developed a system that uses lasers and fiber optics to measure very small changes (deflections) in a rifle barrel. These deflections are recorded with laser sensors, and then algorithms are used to compute the resultant changes in bullet trajectory. Using computer-calculated trajectories, the digital sighting system’s “virtual” reticle automatically adjusts to compensate for barrel deflection, as well as changing environmental conditions. The microprocessor-controlled digital reticle can adjust to 1/1000th of a Minute of Angle (MOA). That makes it far more precise than any conventional riflescope reticle.
ORNL Barrel Sensor with Compensating Reticle
Shown below is a laboratory prototype of Oak Ridge National Laboratory’s Reticle Compensating Rifle Barrel Reference Sensor. This system precisely measures the deflection of the barrel relative to the sight and then electronically makes the necessary corrections. The system was developed by a team led by Oak Ridge National Laboratory’s Slobodan Rajic, shown in the photo.
The Reticle Compensating Rifle Barrel Reference Sensor takes the guesswork out of shooting by shifting the burden of knowing the relative position between the barrel and the weapon sight axes from the shooter to an electronic sensor. The system precisely measures the deflection of the barrel relative to the sight and then electronically realigns the moving reticle, or crosshairs, with the true position of the barrel, or bore axis.
“When a weapon is sighted in, the aim point and bullet point of impact coincide,” Rajic said. “However, in the field, anything that comes into contact with the barrel can cause perturbation of the barrel and induce errors.”
With modern high-caliber rifles boasting ranges of up to two miles, even very small barrel disruptions can cause a shooter to miss by a wide margin. That makes this technology indispensable from a marksman’s perspective, Rajic said.
From a technological standpoint, the approach is straightforward. ORNL starts with fluted barrels (the flutes play a key role). With the ORNL technology, glass optical fibers are placed into the flutes. The sensor system contains a laser diode that sends a signal beam into the optical fibers parallel to the bore axis of the barrel.
“The optical fibers are designed to split the laser beam twice, sending one beam along the top of the rifle barrel and another light beam along the side of the barrel,” Rajic said. “Thus, we can measure both the vertical and horizontal barrel deflection.”
Through a combination of algorithms, optics and additional sensor inputs, the system can take into account distance and other factors affecting the bullet trajectory. Ultimately, the whole optical/laser/digital system provides the shooter with crosshairs that automatically adjust for conditions in real time.
A Compensating Reticle with 1/1000 MOA Precision
Skeptics of electronic sighting systems have complained that the resolution of a digital rifle-sight is too crude to allow precise aiming. There simply aren’t enough pixels on a viewscreen to allow ultra-precise aiming at long-range targets, shooters have said. In fairness, the existing commercially-available digital rifle sighting systems HAVE been crude — with a lo-rez screens like you might find in a portable GPS.
Well you can forget all that. ORCL has achieved a break-through in digital sighting. The bar has been raised — by an order of magnitude. The resolution of ORNL’s digital, sensor-informed Compensating Reticle is 125 times better than that of traditional target reticles, which can normally be adjusted by one-eighth Minute of Angle (MOA) (at best). Now get this — the ORNL sensor can sense angular displacement and shift the reticle by 1/1,000th of a minute of angle. While this system is expensive, and designed (at this point) for the military, this technology could eventually benefit sport shooters. A decade from now, we would not be surprised if long-range civilian shooters commonly use electronically-enhanced optics, with digital reticles that automatically compensate for bullet drop (and maybe even windage).
ORNL scientists are also working on technology that could yield much more precise and accurate plots of bullet trajectories. We will no longer have to rely on “guesstimated” data inputs, and certain assumptions about bullet drag factors. Rajic and colleagues are developing a laser-based, bullet tracking system that would record plot the bullet’s actual flight path while the bullet is in the air. In other words, this tracking system would be able to plot the bullet’s true trajectory from muzzle to target. That is much differerent than current ballistic “solvers” which merely draw a predicted arc based on muzzle velocity, wind and temp inputs, and a reference BC value.
Oak Ridge National Laboratory is a multi-program science and technology laboratory managed for the U.S. Department of Energy by UT-Battelle, LLC. Over 3000 scientists and engineers at ORNL conduct basic and applied research and development to create scientific knowledge and new technology in key areas of science, energy, the environment, and national security.

Eurooptics.com now carries the impressive Vectronix Terrapin Laser Rangefinder. The $1995.00 Terrapin is a high-grade, milspec device rated to 2400m, well beyond the stated ranges for LRFs in the $600-$1000 class. Field reports indicated that the Terrapin is very good. One field tester, using a Terrapin set on a tripod, said the Terrapin hit 16″ plates at 800 yards more reliably than a Swarovski Laserguide. Ranging a small object like that at 800 yards is a tough test for any LRF. The Terrapin performs well on smaller objects because it has extremely tight beam divergence (this means the beam doesn’t spread out like a wide cone at long range).
The reports we’ve received indicate that the Vectronix lives up to expectations created by its 2400m distance rating. Jason Baney reports: “This Vectronics is impressive. In the right conditions, these units can range well beyond 2000 yards. On a Snipers’ Hide Thread, Vectronix Terrapin owners have reported ranging successfully past 3000 yards on large objects.” Available in tan or green, the Terrapin has a rugged aluminum inner housing and is rated to be waterproof with 60 minutes of immersion. It is easy to hold, and weighs just 1.1 pounds. Efficient electronics allow the Terrapin to make over 7,000 ranging “shots” before the two CR123 batteries need to be replaced.

Here’s a very good deal if you’re looking for a premium Laser Rangefinder with excellent long-range performance and a compact form factor. The popular Leica CRF 1600 laser rangefinder is now on sale at EuroOptic.com for just $649.00. That represents a $150.00 savings over the previous price. The hundred and fifty bucks you save can pay for other gear items you need.
Why is the CRF 1600 on sale? Leica is bringing out a CRF 1600-B in June, 2012. The newer ‘1600-B’ model will have more bells and whistles, yet it will be sold at the $799.00 price. That means the price has been slashed on the current CRF 1600.
Should you wait for the ‘1600-B’ version? That depends. The new CRF 1600-B model offers built-in angle correction plus an LED output for holdovers (in inches or cm). It can also display the elevation clicks you need at particular distances, based on reference to a set of internal ballistics curves. That sounds cool, but if you already have a come-up table (as you probably do), all you really need is an accurate range to the target — and the CRF 1600 can definitely deliver that. The current CRF 1600 does offer hold-over values (in cm or inches), based on built-in ballistics curves, but it doesn’t have an inclinometer and it doesn’t provide click-value read-outs. If you don’t need the “fancy extras”, or you don’t want to wait until June for the ‘1600-B’ model, it makes sense to pick up a CRF 1600 now at the $649.00 sale price.

Two Sandia National Laboratories engineers, both hunters, have developed a patented design for a laser-guided bullet. The 4″-long laser-guided projectile has made hits at ranges up to 2000 meters. No this is NOT an April Fools’ joke. The projectile shoots from a smooth-bore rifle and uses small, movable fins to adjust its trajectory. The fins are controlled by micro-sized actuators in response to signals from a tiny, onboard laser-sensor. Plastic sabots provide a gas seal and protect the delicate fins while the projectile is in the firearm’s barrel.
Click Here for Video News Report on Sandia-developed Guided Bullet
Sandia researchers Red Jones and Brian Kast (and colleagues) have invented a dart-like, self-guided bullet for small-caliber, smooth-bore firearms that could hit laser-designated targets at distances of more than a mile. “We have a very promising technology to guide small projectiles that could be fully developed inexpensively and rapidly,” Jones said. Researchers have had initial success testing the design in computer simulations and in field tests of prototypes, built from commercially available parts, Jones said. While engineering issues remain, “we’re confident in our science base and we’re confident the engineering-technology base is there to solve the problems,” he said.
Sandia’s design for the four-inch-long bullet includes an optical sensor in the nose to detect a laser beam on a target. The sensor sends information to guidance and control electronics that use an algorithm in an eight-bit central processing unit to command electromagnetic actuators. These actuators steer tiny fins that guide the bullet to the target.
Fin-Stabilization — Like on a Guided Missile
The guided projectile is shot from smooth bore barrel with no rifling. While conventional bullets are spin-stabilized, Scandia’s guided bullet doesn’t spin in flight. To enable the guided bullet to adjust its trajectory toward a target and to simplify the design, the spin had to go, Jones said. As on most guided missiles, fins both stabilize and steer the projectile. But on this projectile, the fins are tiny — just a few millimeters tall.
The bullet flies straight due to its aerodynamically stable design, which consists of a center of gravity that sits forward in the projectile and tiny fins that enable it to fly without spin, just as a dart does, he said. The four-inch-long bullet has actuators that steer tiny fins that guide it to its target.
Projectile Flies at 2400 fps — More Speed Is Possible
Testing has shown the electromagnetic actuator performs well and the bullet can reach speeds of 2,400 feet per second, or Mach 2.1, using commercially available gunpowder. The researchers are confident it could reach standard military speeds using customized gunpowder.
Sub-MOA Accuracy at 1000m — No Matter What the Wind Does
Computer aerodynamic modeling shows the design would result in dramatic improvements in accuracy, Jones said. Computer simulations showed an unguided bullet under real-world conditions could miss a target more than a half mile away (1,000 meters away) by 9.8 yards (9 meters), but a guided bullet would get within 8 inches (0.2 meters), according to the patent.
The prototype does not require a device found in guided missiles called an inertial measuring unit, which would have added substantially to its cost. Instead, the researchers found that the bullet’s relatively small size when compared to guided missiles “is helping us all around. It’s kind of a fortuitous thing that none of us saw when we started,” Jones said.
As the bullet flies through the air, it pitches and yaws at a set rate based on its mass and size. In larger guided missiles, the rate of flight-path corrections is relatively slow, so each correction needs to be very precise because fewer corrections are possible during flight. But “the natural body frequency of this bullet is about 30 hertz, so we can make corrections 30 times per second. That means we can over-correct, so we don’t have to be as precise each time,” Jones said.
Projectile Becomes More Stable After Launch
Researchers also filmed high-speed video of the bullet radically pitching as it exited the barrel. The bullet pitches less as it flies down range, a phenomenon known to long-range firearms experts as “going to sleep.” Because the bullet’s motions settle the longer it is in flight, accuracy improves at longer ranges, Jones said. “Nobody had ever seen that, but we’ve got high-speed video photography that shows that it’s true,” he said. (See below)
Here’s a clever product that provides visual feedback of your aim on the target while you dry-fire. LaserLyte, makers of laser pistol sights and bore-sighting tools, has come up with a smart new application of a miniature laser system. The new caliber-specific Laser Trainer Cartridge fits inside the pistol chamber and features a firing-pin activated switch that indicates bullet impact with a bright red laser dot. To practice, simply cock the hammer or striker, and pull the trigger as you would normally. When the firing pin hits the Laser Trainer Cartridge, a bright red laser displays on your target for 100 milliseconds. Available for 9mm, .40 S&W, and .45 ACP, the $99.95 (MSRP) Laser Training Cartridges are rimless so you can work the slide without ejecting the Laser Cartridges.
With a Laser Trainer Cartridge in the chamber of your 9mm, .40 S&W, or .45 ACP pistol, you can practice your trigger pull and sight acquisition. But unlike traditional dry-firing, you can see your point of aim when you “break the shot”. This modified cartridge is rimless, so the Laser Trainer Cartridge is not expelled during dry fire, which allows for tap, rack, bang or malfunction training drills. A hardened rubber plunger on the laser also acts as a built-in snap cap to protect the firing pin. The Laser Trainer Cartridge requires three #377 batteries, good for approximately 3,000 shots.

With larger-caliber rifles, manual bore-sighting (with your eyeballs) is not that difficult. Just remove the bolt, and look through the bore at the target. It helps to have a well-illuminated, high-contrast circle target about 8″ to 12″ in diameter. When you’ve got the target centered, then stabilize your gun on the rest so it doesn’t move from that position. Because bore-sighting the old-fashioned way is not that difficult with larger calibers, we’re not sure laser bore-sighters and other gadgets are really needed.
However, with smaller calibers (.17, .204, .223), manual bore-sighting is not so easy. Much less light makes its way down the smaller-diameter bore, and it’s more difficult to find the target on the background. That’s why we welcome two new products from Sightmark. This Texas-based company has developed in-chamber laser boresights for 17 HMR and .22LR rimfire guns. The tiny boresights are correctly dimensioned so they fit in rimfire chambers just like normal 17 HMR or .22LR cartridges. With the boresight in place, simply flick a switch on the battery pack and the laser dot shows exactly where the rifle is aimed. The dot is roughly 2″ in diameter at 100 yards.
Sightmark rimfire boresights are made from brass, so they are gentle on your chambers. The separate battery pack holds two (2) AAA batteries, which will power the laser for about 30 hours. We like the fact that the battery pack is separate. That makes it easier to swap in new batteries, AND, importantly, the battery pack makes it obvious when the boresight is in use. That lessens the chance that someone could mistakenly try to chamber a live round with the boresight in place.
Sightmark Rimfire Boresights Developed After Extensive Comparison Testing
“We tested every competitor’s chamber boresight for the 17 HMR and .22LR currently on the market and found that they did not work well, so we decided to create one that would,” said James Sellers, president of Sightmark. “Our Sightmark 17 HMR and .22LR boresights are as accurate as our other award-winning chamber boresights, so there’s no guessing if you’re on target”. Sightmark 17 HMR and .22LR Rimfire boresights retail for $47.99 and can be ordered directly from the Sightmark Online Catalog.
