"How to Look Like You're In the Special Forces"

1. First, go buy the biggest watch you can find. A foreign special services officer asked me once whether we recruited guys based on the size of their watches or whether we bought everyone a big watch as a reward after training.
2. Cut the sleeves off your shirt. It’s hot in the Middle East, and guys would cut the sleeves off their operational uniforms. It makes sense in certain situations, but I had to tell my team, “Look, I know it’s hot, but I need you to meet safety parameters. You’re gonna get scratched.”
3. Make it your boss’s job to tell you to get a haircut and a shave.
4. Wear sunglasses. Everywhere. I’ll tell my team, “Hey, we’re inside. We can take off our sunglasses.” But they don’t.
5. Keep quiet. The baddest guys I know are also the quietest. The guy who’s talking about doing badass stuff? He’s probably not the biggest badass in the room. It’s a little like that guy on the football team who wears his letterman jacket all the time.
6. Never say “no.” Your first reaction has to be, “Yes, I can do that,” and then you figure out how. If the president asked me to go to the moon tomorrow, I’d say yes. Then I’d say, “I’ll need some training. And someone who can fly a rocket.” — As told to Brendan Greeley

Econo-Can: A $55 Suppressor
私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。
American Specialty Ammo is selling a registered NFA suppressor for $55 (+ $200 tax stamp) that is nothing more than an adapter to attach a car oil filter to a 1/2-28 threaded barrel. The first bullet punches a hole in the end of the oil filter.
You can buy "spin-on" oil filters for $10 - $20. A used oil filter (soaked with old oil) will only improve its efficiency. Internally oil filters contain fibrous material designed to filter out contaminates from the oil. I think they would eventually wear/burn out when used with firearms.
An oil filter cartridge
This is a very clever concept. It makes me wonder why someone doesn't make a universal suppressor adapter and a range of tubes for various calibers.

Meprolight M21 dual-illuminated Reflex Sight
私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。
With combat experiences from five major wars and concurrent anti-terrorism operations since its founding in 1948, the Israeli Defense Forces or IDF is one of the first military to understood the advantage of reflex sight on small arms for every infantryman. The main reflex sight used by the IDF for the last 20 plus years is the Meprolight M21. It features the always-on dual-illumination by fiber optic collectors during the day and it uses tritium illumination for low light and nighttime.
The Mako Group is the authorized distributor of Meprolight rifle sights in North America. I had a chance to try out a Meprolight M21 reflex sight during an Israeli style carbine course offered by Mako Defense, a sister company of the Mako Group. The version that I tried has the “X” reticle. The M21 is also available with the 16 MOA triangle reticle, 4.3 MOA dot, 5.5 MOA dot and the bullseye (a dot inside of a circle). The tritium lamp has a 10-year guarantee by Mako. It typically lasts up to 14 years before the tritium became unusable. The tritium illumination unit is replaceable by factory service for a reasonable cost. The current production model is actually the Mepro M21m. The –m suffix is for modular design and because of that, every component on the M21m is replaceable and upgradeable. When mounted on an AR15 flat-top, the M21 has lower 1/3 co-witness with iron sights.
The M21’s reticle has an amber color and its 30mm objective lens’ coating has a green color tint to it. Under the bright daylight, the green lens coating is hardly noticeable. As the light becomes dimmer, the green color appears greener. Since human eyes are more sensitive to the green color, by using a green lens tint it helps to increase the optical contrast and makes the reticle stands out. On a reflex sight design, using the green color coating is a common technique to compensate for a dim reticle. In the M21’s case is its tritium lamp. The majority of the M21’s fiber optic collectors are located in the front of the sight with some in small windows in a horseshoe like pattern around the sides and the top. All the fiber optics is behind protective translucent panels with a discreet light grey color.
I found the M21’s amber color reticle works fine in daylight in both the desert and foliage environments and it is adequate in the darkness. The reticle is also sharply focused and without blooming. However, like other fiber optic and tritium lit sight, it has some issues in certain light conditions. The illumination is barely visible in the low interior lighting of a house. Where neither the fiber optic collects enough light nor the tritium lamp is bright enough. According to the Israeli technique, if you can see the target through the objective lens tube, you will hit it at close range. Another oddity is that in a very bright sunny day, if the shooter is in the shadow of a building and looking through the M21, sometime a bright background would washout the reticle. Although the M21 is less prone to that than the Trijicon reflex sights because it has some of its fiber optics on the sides. Not that the M21 is bad, in fact it works beautifully in most light conditions. Just remember that the fiber optic light collector technology has its limitation.
The M21’s tritium illumination is night vision compatible and it has less blooming than other tritium sights through the NVG. The company gets the tritium from the same Swiss manufacturer that also supplies Trijicon. According to Mako, the main difference is that Meprolight only buys the raw tritium instead of having the Swiss to build the whole illumination unit like Trijicon. Meprolight applies their proprietary treatments to the raw tritium before packaging it and also use higher quality focus lens in their tritium tubes.
The Meprolight M21 was specifically developed according IDF’s requirement. The sight has to be tough enough to withstand the punishment by 18 years old conscripts. The IDF is expecting the M21 to last for at least 20 years of hard use. The sight uses no battery, has no external switch, it’s always on and ready to use. The M21’s aircraft grade aluminum housing is sealed against the environment and it’s waterproof. Both the windage and elevation adjustment dials are flush mounted. The M21 features an adjustable QD mount with dual QD levers for mil-spec 1913 rail. Interestingly, the IDF had actually tested the various QD levers on the market. They have found that while the cam types like LaRue and ARMS are better for retaining zero, the cross bolt type that is on the M21 has more tolerance for mishandling. Mako also offers the M21 with a co-witness M16 carrying handle mount. Noted that the user can’t switch out the mount, it’s factory calibrated to the sight’s lens and it’s permanently installed.

One of the youtube user we are following is FPSRussia. In this video he is showing a Quadrotor with a machine gun installed, operated remotely by a tablet. Although there are some speculation as to the authenticity of this video, it is still fun to watch.
