The problem with most flashlights is that, when you really need them the most, you often find the batteries are discharged. A flashlight with dead batteries is useless in an emergency. The new LED Magna flashlight doesn’t need batteries at all. Inside the housing is a copper coil. By shaking the handle of the unit you cause a magnet to pass back and forth through the coil. This generates electricity which is stored in a capacitor. Just a few shakes will generate light.
The LED Magna Light costs just $4.68 plus shipping from www.techdeals.us. At that price you can afford to keep one of these lamps in each of your vehicles, plus one in your range kit or “bug-out” bag. Now we just wish somebody made kinetic-powered cell phones and GPS units. It seems we are always struggling with low batteries on those often-used electronic devices. And why hasn’t anybody put a solar panel on the back of the iPhone yet?
Imagine a riflescope that could sense target distance and shift from wide field-of-view/low magnification for closer shots to higher magnification for longer-range shots. Just think of the benefits for a hunter. He could just place his cross-hairs on a buck and the scope would automatically zoom to the optimal magnification. Does this sound like science fiction?
Well the Defense Advanced Research Projects Agency (DARPA) is betting millions of tax dollars that an auto-adjusting rifle scope will soon be science FACT. DARPA recently awarded Lockheed Martin a $3.93 contract to develop a “next generation” Dynamic Image Gunsight Optic, aka DInGO. The DInGO scope automatically calculates the range with a low power laser rangefinder, digitally zooms in on it and accounts for environmental conditions such as wind using sensors built into the scope. It then projects the bullet’s point-of-impact calculated from the embedded ballistics computer. DInGO is based on Lockheed Martin’s One Shot Advanced Sighting System, which utilizes similar technology to automatically transmit crosswind information to a sniper’s scope and move the crosshairs to show the corrected point of aim.
“Current scopes are optimized for a single target range, impacting soldiers’ effectiveness and survivability when engaging targets at different distances,” said Dan Schultz, vice president and general manager of Lockheed Martin’s Mission Systems & Sensors Ship & Aviation Systems business. “DInGO will solve this problem, significantly increasing soldiers’ ability to rapidly reconfigure optics for use from short to long ranges and improving marksmanship capabilities for all soldiers.”
While DInGo scope technology will first be implemented for the military on M-4 and M-16 rifles, eventually this automatic ranging/zooming system could be adapted to hunting rifles. Such a system would be great for game hunters. When the prey appears at close range, the scope would provide a relatively low magnification level for enhanced field of view. If the animal was much farther away, the scope would autmatically increase magnification to allow more precise aiming. Hopefully this will be one example of military technology “trickling down” to the general public for sporting use.
Other Scopes with Built-In Laser Rangefinders
Both Burris and Zeiss currently offer hunting scopes with integrated laser-rangefinders that calculate holdover, based on target distance. The Burris Eliminator even projects the calculated aiming (hold) point as a red dot on the vertical crosshair. Shown below is the view through the lens of the Burris Eliminator scope, with the red dot showing holding point. Just place the red dot on the center of the target and pull the trigger. However, neither the Burris nor Zeiss rangefinding scopes automatically adjust magnification/field of view. Zooming in or out must still be done manually. That’s where the DInGO system offers something radically new.
Kahr Arms has acquired firearms manufacturer, Magnum Research, Inc., of Minnesota. Magnum Research, founded in 1979, is best known for its super-sized big-bore Desert Eagle pistol, but it also sells a 1911-style pistol, compact “Baby” and “Micro” Desert Eagle carry pistols, BFR revolvers, and the Mountain Eagle™ MagnumLite® line of rifles. The Desert Eagle is a large-framed gas-operated semi-automatic pistol designed by Magnum Research in the USA, and manufactured primarily in Israel by IWI (Israel Weapon Industries, formerly Israel Military Industries, IMI). The Baby Eagle is based on the CZ75 design, updated by IWI.
Kahr Arms currently sells mostly striker-fired semi-automatic pistols, aimed primarily at the personal defense and concealed carry markets. The acquisition of Magnum Research gives Kahr a line of traditional hammer-fired pistols and revolvers. Now Kahr can also expand into the hunting and varminting markets with the Mountain Eagle series of rifles. These feature carbon-wrapped barrels fitted to “custom-tuned” Rem 700 actions in H-S Precision or Hogue stocks. The MSRP on Mountain Eagle rifles is $2173.00 — that’s expensive compared to a factory Remington, but the price is half what Christensen Arms charges for similar rifles with carbon-wrapped barrels. No doubt Kahr hopes to steal some of Christensen’s customers.
Here’s an item that should interest 3-Gun and Multi-Gun competitors using AR rifles. Magpul Industries has filed for a patent on a new “quad-stack” magazine that may hold as many as 60 rounds, yet feed through a normal AR15 mag well. (In Multi-Gun matches, ultra-high-capacity magazines can provide a competitive edge in high-round-count stages.) While Magpul is renowned for its innovative engineering, we wonder if this new mag design was inspired, at least in part, by the Russians. Earlier this year, the Izhmash OJSC factory in Russia revealed a quad-stack 60-round magazine for the new AK-200 rifle, successor to the AK-47.
An explanation of how Magpul’s new quad-stack AR magazine works is found on The Firearm Blog, which reports: “The design is quite straight forward. A central partition separates two dual staggered round stacks. Two springs are used, a lower stronger spring and a weaker top spring[.]”

DeLorme has come out with a new, handheld GPS that can send messages via satellite, using SPOT satellite technology. What’s the benefit? This allows a user to stay in touch with others (or reach emergency responders) even when out of cell phone range. With its texting ability, DeLorme’s new Earthmate PN-60w offers many of the benefits of a satellite phone, at a fraction of the cost.
The Earthmate PN-60w is the world’s first handheld GPS that enables Type & Send text messaging via satellite. With the PN-60w you can send a text message (with your location), from pretty much any spot on the globe. Having that capability can be a life-saver for a hunter or hiker stranded in the wilderness. Messages are created on the PN-60w’s internal keyboard, sent wirelessly to the separate SPOT communicator, then relayed via satellite to individual email addresses, cell phones, buddy lists, and/or geo-caching websites. In case of emergency, SOS messages can be sent directly to rescue services with the user’s GPS coordinates embedded.
As a stand-alone GPS, the Earthmate PN-60w has premium navigation features including a 32-channel GPS chipset, dual-core processor, 3-axis electronic compass, barometric altimeter, elevation profiles, and GPX file transfers. The Earthmate PN-60w comes with DeLorme Topo North America GPS maps and desktop software included, with topographic and street coverage of the U.S. and Canada. The unit can also display high-resolution aerial imagery, official USGS and Canada topo maps, NOAA nautical charts, and Navionics charts, (all extra cost). The text messaging, track progress, and emergency SOS/911 features are activated via separate fee-based SPOT subscriptions (not included in hardware price). MSRP for the PN-60w and SPOT Communicator bundle is $549.00, with product availability in July.

Since it was first released in 1965, Cartridges of the World by Frank Barnes, has been considered the definitive print resource on firearm cartridges. The current 12th Edition, edited by Holt Bodinson, was released late last year. The 568-page 12th Edition now describes over 1500 cartridges (from 0.1 inch to 0.95 inch caliber). This edition has interesting new articles on cartridge design and performance. The book includes dimensions, illustrations, a short history, and sample loading data for over 1500 different cartridges, including virtually every significant cartridge introduced since the early 1870s, with separate chapters on rimfires, shotgun shells, sporting rifle cartridges from the United States and Canada, Britain, and Europe, plus handgun cartridges, military cartridges, and limited production “wildcat” and “proprietary” cartridges. You won’t find all the narrow-focus or obscure wildcats, but the book is still a useful resource, well worth owning. It’s a “must-have” item for any serious cartridge collector.
Frank C. Barnes (1918-1992) began collecting information on handgun cartridges at the early age of 12, thanks to his father, a police officer. Frank Barnes was an innovative cartridge designer, who invented the original 308 x 1.5″ Barnes, predecessor of the 30BR case. Before Frank began a law enforcement career, he was a college professor. Frank was also a pilot, and a race-car driver.
Cartridges of the World was first published in 1965. It’s lived through 12 editions and can be found on many reloaders’ bookshelves today. Suggested retail for the book is $32.99, but MidwayUSA currently sells the 12th Edition for $19.99 plus shipping (Midway item 242319). Amazon.com offers the book for $21.77 with free shipping on combined orders over $25.00.
For the first time in six years, Armalite is producing a special run of semi-auto AR-10 rifles chambered in .243 Winchester. The .243 Win chambering is excellent for long-range target shooting as well as hunting most North American deer species (you want a bigger round for Elk). The new Armalite features a 20″ barrel, 2-stage “tactical” trigger, and a flat-top receiver with Picatinny rail. Units should start shipping in late July, with an MSRP of approximately $1600.00.
Looking to expand its share of the burgeoning market for tactical rifles, Remington has released a new Hogue-stocked Rem 700 variant with a 20″ barrel threaded for sound moderators (suppressors). Remington calls the new rifle the Model 700™ SPS™ Tactical AAC®-SD. (Somebody at Remington got carried away with the acronyms.) There’s nothing new or remarkable to be found in the gun’s internals. It’s pretty much a standard short-action Rem 700 with a 1:10″-twist heavy barrel chambered in .308 Winchester. The rifle does feature a Hogue® Overmolded Ghillie Green™ pillar-bedded stock, an upgrade over the inexpensive synthetic stocks on entry-level Rem 700s.
We generally like the build quality of the Hogue stocks, but some of our tactical testers have complained that the over-molded design is a bit flexy compared to a McMillan or Manners tactical stock. If you’re planning to use the rifle for mostly prone work, you’ll also want to add some sort of buttpad spacer system to allow length-of-pull adjustment. MSRP for the SPS Tactical AAC-SD is $757.00.
MidwayUSA has released a new 3-10x40mm MIL/MIL Tactical Grand Slam scope, made exclusively for MidwayUSA by Weaver. The scope features 1/10 mil radian (MIL) clicks, with a claimed 56 MOA (16.5 MIL) of BOTH windage and elevation adjustment. On sale through May 31, 2010 for just $299.00, the scope is regularly priced at $399.00. Even at the $400.00 mark, the scope is one of the most affordable optics combining a mildot reticle with mil-based clicks — a smarter system than what you find on so-called “tactical” scopes combining mildot reticles with 1/4-MOA clicks.
With the MIL/MIL arrangement you can directly translate what you see in the scope to click values. For example, with a MIL/MIL scope, a shot 1.5 mils low would require an elevation turret adjustment of 1.5 mils (15 clicks). This eliminates MOA conversions and allows the shooter to make adjustments quickly without having to do any math.
This tactical scope features Weaver’s Micro-trac® adjustment system, resettable 1/10 mil radian (MIL) windage and elevation turrets and a Mil-dot reticle. The scope has a one-piece tube and is claimed to be waterproof, fogproof and shockproof. The new Grand Slam 3-10X boasts a fast-focus eyepiece adjustment, and Weaver claims the multi-coated, Japanese-made lenses afford 94% light transmission. That’s a pretty tall claim regarding light transmission; if it’s true, then this scope should have very good low-light performance. We suspect the true average light transmission (across all visible wavelengths) is quite a bit lower. 94% transmission would put the new scope on a par with premium optics costing $1200.00 or more — which is unlikely. As noted above, the new 3-10x40mm scope is on sale for $299.00 for the rest of May, 2010. The scope is covered by Weaver’s Lifetime Warranty.
