AR-15 Fiber optic Sight
Ever have a hard time picking up your front sight in low light? The AR15/M16 series rifle has developed into an excellent system with more accessories supporting it than any other weapon on the planet. For good reason. With the correct barrel twist and bullet (sadly, something, the military has turned away from with it's 1:7 twist), it's highly effective and reliable. Still, there is always room for more and Ned Scheer of has recently patented a new front sight called the SIGHTLINK, Part no. FOS-070-MS1, that will, I believe, prove to be a great success. Based on the fiber optic sights one might find on rifles and shotguns, Ned has gone the extra mile and made an AR15 specific sight that not only adjusts for elevation as the original, but can then be adjusted again so that the blade of the sight aligns properly. This special feature is what sets it apart from all others and is what generated the patent. Most fiber optic sights can only be adjusted in 180 degree rotations, which makes it impossible to exactly set your front sight without having to readjust your rear sight. In other words, as is typical of National Match sights and fiber optic sights, you would normally only be able to get "close" to the perfect zero, but then you have to diddle with your rear sight until you get your actual Center Mass or Six O'clock hold as desired. On the AR-15 with Match sights, this is only a minor inconvenience, but on the A1 it is a total washout. An AR15A2 with a standard rear sight also presents a problem, as it does not have the fine adjustability of the A2 Match sight.

 This unique rotation feature allowed a second equally unique feature to be worked into the design. Once your elevation is set, you now have a choice of two diameters for the fiber optic dot. A large diameter dot is available for low light or quick acquisition of your target, or a finer, smaller dot for precise aim in prone position or better-lighted situations. A simple rotation of the sight blade and you now have a choice not available with any other sight on the market.
Also included are three, 3.75" long stands of fiber optic rod. Red, Green, and Yellow. The sight itself comes with a Red fiber optic rod already installed, but the additional rods may be used to experiment with color to find the one that works best for you. The sight blade itself is 1/4" long, so you have, in effect, an additional 11 to 12, 1/4" rods in each color. Figure 12 replacement AR15 rods if you are not too sloppy at cutting the rod into segments. Changing out the rods is explained in detail in the fully illustrated instruction booklet provided with the kit. The manual is a glossy full color booklet, a far cry from some of the black and white Xeroxed instruction books I've become accustomed to seeing.

Installation of the SIGHTLINK is simple. Simple remove the original front sight. Remove the standard detent block.provides a replacement detent block designed for use with this sight. You will reuse the factory detent spring. Install the new sight per the instructions and head to the range. Set your rear sight for your chosen zero range and then adjust the front sight for elevation until you are on zero for elevation. It's that simple. As you adjust the front ar-ar15 sights for each click in search of your zero, it's a simple matter of realigning the front sight blade to line up with the bore of the rifle. Each click of the bottom notch on the SIGHTLINK is 5/8th M.O.A., or 5/8ths of an inch at 100 yards. Mil. Spec. is a whopping 1.25 MOA per click. So you can see the immediate advantage.
Listed Retail for the kit is $49.95. This seems high until you consider the completeness of the kit. Fiber optic sights run approximately $10 a foot. Sight adjustment tools $15.00 and standard front sights anywhere from $11 to $15. In addition you are getting a fully adjustable fiber optic sight, a detent wrench and a replacement detent block. Not to mention the obvious improvement in sight acquisition.
