Gear Review Shield Sights RMS Reflex Mini SightShield Sights isnt yet a household name in the U. S., but it should be and likely will be soon enough. As tough as Trijicons legendary ACOG scopes, the lowprofile RMR Ruggedized Miniature Reflex sight enables fast, botheyesopen, target acquisitioneven. Forged of 7075 aircraft aluminum alloy, the Trijicon RMR LED Reflex Sight delivers legendary toughness in a compact package. This makes it great for multiple primary.

British military and special forces. They made the red dots for Trijicon back in the day and were early innovators in the LED red dot optic game. SHIELD makes the JPoint that has been on my G1. MOS since day one, but now theyre selling their own, improved mini red dot on this side of the pond, and its called the RMS. When placed next to the JPoint which is sold as the SHIELD SMS outside the U. Sig Sauer P320 RX FullSize Firearms. Featuring SIG SAUERs exclusive sidemounted optic, the ROMEO1, the RX will ensure faster sight acquisition on target. Simply. S.   SHIELD left, JPoint right in both photos above the RMS is obviously extremely similar. Dimensionally its effectively identical. They both use a polycarbonate lens instead of a glass one, and they both run for a shockingly long time on a single CR2. They both fit the same mounts. The RMS, though, is metal rather than plastic. Its machined from a block of aluminum then hard coat anodized. Dont worry, its still a featherweight at 1. Trijicon RMR. The RMS exudes a look and feel of higher quality due to the materials, precise machining, and nice finish. Those lightening cuts in the sides add some flair and visual interest, too. I must admit, though, that despite the JPoints and RMS two to three year battery life with regular use, the feature I was most excited for on the RMS is its side opening battery tray. Whereas the JPoint had to be removed from the weapon in order to swap the battery as is the case with most micro red dots the RMS is offered with a slide out tray that allows the battery to be swapped quickly and easily while the sight remains firmly mounted. Another great feature of the RMS is its thin base. Its so compact that, with the right mount or milling job, itll actually co witness with standard height iron sights. No need to purchase extra tall suppressor sights so they can be seen and aligned through the window of the optic. Aside from the JPoint, Im not sure theres another red dot on the market that can make this claim. Taking that a step further, you may have noticed that my GLOCK doesnt even have a factory rear sight on it. While the RMS works perfectly with the rear sight in place, I just didnt see a point to keeping it. The RMS has its own rear sight notch built into the body, and it happens to be the perfect height for the factory GLOCK front sight. As I generally prefer an all black rear vs. GLOCK U line rear, it was an easy decision to drift that superfluous piece of plastic off. Thanks to the polycarbonate lens, theres no distortion or color shift when looking through the RMS. It doesnt require a red coating and gets only an anti reflection and anti scratch treatment. Glare and visual signature from downrange are reduced as compared to a glass lens RDS. Additionally, the polymer lens is both lighter weight and more impact resistant than glass. It falls short vs. A light sensor in the RMS adjusts the dots brightness automatically. And very well, I might add. For instance, if youre in deep shade but your target is in full sun, the sensor does a good job of recognizing the brightness of your target area and adjusting the dot accordingly. The 4 MOA or 8 MOA dot gets plenty bright enough to be clearly seen even in full, glaring daylight against a light background. The photo above does not do it justice, as my cell phone simply couldnt handle the situation. Go two photos up to the one where Im holding that tree hostage and the crisp, clean, 4 MOA dot on this RMS is that bright and obvious even in full sun, too. Then in the dark it automatically and almost instantaneously adjusts down. Low enough, in fact, to be night vision compatible. By the way, left in the dark in a safe, with the cap on, or carried concealed under your clothes the battery is good for at least four years. With a good dozen or more mounting options, the RMS can be readily adapted to other platforms. Mount it to a race gun, onto an ACOG, Elcan Specter, or a scope, off at a 4. AR, to anything with a Picatinny rail with or without risers, to a shotgun, to an MP5 or a USP, to a standard GLOCK via the rear sight dovetail, and more.

Ratings out of five starsForm Factor Its likely the lightest mini red dot on the market and it has the flattest base, too. So flat, in fact, that standard height pistol sights co witness with it. The window size is more than sufficient, yet doesnt add width to most pistol slides and is small enough to effectively use as a ghost ring sight window of death at closer ranges. It has a relatively thin bezel and a nice shape to the front face for use in slide manipulation. Aesthetically the RMS looks cool, but is still understated compared to some of the competition. Function risp dot. Parallax free, distortion free, and color shift free. Automatic brightness adjustment works incredibly well from as dim to as bright as one could possibly need it. One CR2. 03. 2 runs it for 2 3 years of regular use and can be replaced without removing the optic. The RMS is so lightweight that it shouldnt affect slide cycling on any pistol. Integrated rear sight notch works just right on a GLOCK likely other pistols, too and standard height sights can co witness. Strong enough to withstand drops and direct impacts or use as the sole means of racking a pistol slide. Highly water resistant. Quality achining and finish are near on flawless. Fit is perfect. It holds up to abuse. Ive experienced a major brand micro red dot fritzing out on my pistol before and have seen a few with cracked lenses. The polycarbonate lens in the RMS is not only clearer and more distortion free than most glass ones but it weighs less and is, in most ways, more durable. The RMS also seems to shrug off water immersion better than most of the competition thats also designed with open bottom battery trays. Overall think the SHIELD RMS is the best micro red dot sight on the market, or at least as good as it gets. No buttons, no settings, it just works and works well. Red dot sight Wikipedia. View through Tasco Pro. Point red dot sight model PDP2. ST on a Ruger 1. Made in Japan for Tasco, the Pro. Point 2 was one of the first red dot sight models to become widely popular. A red dot sight is a common classification1 for a type of non magnifyingreflector or reflex sight for firearms, and other devices that require aiming, that gives the user an aimpoint in the form of an illuminated red dot. A standard design uses a red light emitting diode LED at the focus of collimating optics which generates a dot style illuminated reticle that stays in alignment with the weapon the sight is attached to regardless of eye position nearly parallax free. They are considered to be fast acquisition and easy to use gun sights for target shooting, hunting, and in police and military applications. Aside from firearm applications, they are also used on cameras and telescopes. On cameras they are used to photograph flying aircraft, birds in flight, and other distant, quickly moving subjects. Telescopes have a narrow field of view and therefore are often equipped with a secondary finder scope such as a red dot sight. Descriptionedit. Diagram of a typical red dot sight using a collimating mirror with a light emitting diode at its focus that creates a virtual dot image at infinity. The typical configuration for a red dot sight is a tilted spherical mirror reflector with a red light emitting diode LED at its off axis focus. The mirror has a partially silvered multilayer dielectric dichroic coating designed to reflect just the red spectrum allowing it to pass through most other light. The LED used is usually deep red 6. The size of the dot generated by the LED is controlled by an aperture hole in front of it made from metal or coated glass. The LED as a reticle is an innovation that greatly improves the reliability and general usefulness of the sight. There is no need for other optical elements to focus light behind a reticle. And the LED itself is solid state and consumes very little power, allowing battery powered sights to run for hundreds and even tens of thousands of hours. Using a dot shaped reticle also greatly simplifies the sight since the small diameter image does not require a sophisticated optical reflector to focus it. More complex reticle patterns such as cross hairs or concentric circles can be used but need more complex aberration free optics. Like other reflector sights, the collimated image of the red dot is only truly parallax free at infinity, with an error circle equal to the diameter of the collimating optics for any target at a finite distance. This is compensated for by keeping the dot in the middle of the optical window sighting down the sights optical axis. Some manufacturers modify the focus of the LEDoptical collimator combination, making models with the optical collimator set to focus the dot at a finite distance. These have a maximum amount of parallax due to eye movement, equal to the size of the optical window, at close range, diminishing to a minimal amount at the set distance somewhere around a desired target range of 2. Sights may also use a more sophisticated optical system that compensates for off axis spherical aberration, an error that can cause the dot position to diverge off the sights optical axis with change in eye position. The optics used is a type of mangin mirror system, consisting of a meniscus lens corrector element combined with the semi reflective mirror, sometimes referred to in advertising as a two lens or double lens system. Although these are referred to as parallax free sights, the system only keeps the aiming dot in alignment with the sight itself and does not compensate the inherent parallax errors induced by a collimated sight. Red dot sights generally fall into two categories, tube or open designs. Tube sights look similar to a standard telescopic sight, with a cylindrical tube containing the optics. Tube sights offer the option of fitted dust covers and the ability to add filters, such as polarizing or haze filters, and glare reducing sunshades. Since a reflector sight only really needs a single optical surface, the reflector, the tube is not needed. This allows for non tubed open sights that consist of a flat base, with a single loop of material to support the reflective optics. Most red dot sights have either active or passive adjustments for the dot brightness, allowing a very bright dot for high visibility in bright conditions, and a very dim dot to prevent loss of night vision in low light conditions. HistoryeditThe idea of attaching a reflector or reflex sight to a firearm has been around since the sights invention in 1. Many different types of reflector sights specifically designed for firearms have been marketed over the past half century,1. One, the Weaver Qwik Point, even presented the viewer with a red aiming dot due to the red plastic light pipe used to collect ambient light. All had the reticle illumination drawback common with reflector sights small enough for a firearm proper ambient lighting could not be depended on and incandescent light bulbs could drain a battery in a few hours. In 1. 97. 5 the Swedish optics company Aimpoint AB marketed the first electronic red dot sight combining a reflecting curved mirror and a light emitting diode, based on a design by Helsingborg engineer John Arne Ingemund Ekstrand. The sight was called the Aimpoint Electronic and had a closed tube design that could be mounted similar to a telescopic sight. The LED could run for 1. Other manufacturers soon followed with over a dozen offering models today. Newer generation red dot sights were produced with lower power consumption LEDs and power saving electronics, allowing them to run for years without being turned off. In 2. 00. 0 the US military introduced a red dot sight into field use, the Aimpoint Comp. M2, designated the M6. Close Combat Optic. ReticleseditRed dot sight reticle sizes are measured in either minutes of angle moa or milliradians mil which both are angular measurements, making them handy units to use in ballistics. Mils are practical when using SI units for range and subtensions, and can be calculated by measuring the group size in millimeters or in centimeters and multiplying by a factor of 1. Moa is another convenient measure for shooters using English units, since 1 moa subtends approximately 1. While moa sights have traditionally been popular in the U. S., scope sights with mil adjustments and reticles are now also becoming increasingly popular in the U. S. 1. 5The most common reticles used today in red dot sights both for handguns and rifles are small dots covering beetween 2 to 5 moa 0. The choice of red dot reticle size depends on the user needs. Yamaha Breeze Serial Number Location. A larger and brighter red dot makes for faster target acquisition, but may obscure the target and thereby inhibit precise aiming, while a smaller and dim dot allows for more precise but slower aiming. The 5 moa 1. 5 mil dot is small enough not to obscure most targets, and large enough for most to quickly acquire a proper sight picture. When red dot sights started to appear at the practical shooting competition circuit in the 1. However, as red dot technology and production quality has advanced, the market trend in all types of sport shooting has gone towards the smaller dots used today.
