On a 1x, however, I will readily acknowledge the BDC is the better choice. Normally I am against a BDC reticle for precision work, as it isn’t as accurate as a mildot reticle. The Cyclops 2 is a Ballistic Drop Compensating reticle, developed in-house by Primary Arms. While some electronic pure optics have tried a complex BDC reticle, it has never really worked out. An etched reticle is also cleaner, which makes it useful for something besides a simple dot. Even if they can see it, it may look oddly shaped. Some people with astigmatism cannot see a red dot well. In action, velcro strap not pictured.Īnd then we have the advantages unique to a prism, in addition to the battery bit. For all normal shooting conditions, the prism is indistinguishable from a red dot. But despite what modern rifle training will tell you, that is exceedingly rare to have to do. Could you find yourself in such an awkward position, such as short stocking a rifle, that the scope shadow is a factor? Yes, possibly. One point here, about a prism vs a true no parallax red dot. Primary Arms has built in a very forgiving eye box, and is attached to some Picatinny, you won’t even notice. The moment you mount it to a rifle, all of that goes away. You might see some scope shadow creeping in, as this is built like a scope. Like a real scope, it doesn’t quite feel right if you just try and look through it freehand. Putting this optic on gives you almost all the benefits of a red dot, with none of the weaknesses.įirst, this is a hard optic to judge handholding it. In testing by Primary, it survived 7000 rounds on a SCAR 17 (7.62x51mm), which is a notoriously hard recoiling weapon. It is remarkably well built, a kind of quality you can feel. At a price of $249, you get a very robust, very useful prismatic reflex sight. This brings us to the Primary Arms SLx MP. And I certainly wouldn’t pay $2800 for it, even in Monopoly money. We found in testing (long after fielding), that the prism didn’t always snap fully into place, which meant your zero was WAY off, and I wouldn’t take one if you gave it to me. The 1x to 4x throw lever for magnification briefs well but presented problems. It was SOCOM issue, so I have firsthand experience with it. And the ELCAN will break your heart if you price it. The Leupold was a good optic but discontinued about 7 years ago. The only two I can remember on the market in recent memory are from Leupold and Elcan. The problem with prisms prior to this has been either lack of availability or exorbitant price. But in dire circumstances, it does still give you an aiming point as any real scope would. Like an illuminated scope, it does have a battery function that makes the reticle as bright as a red dot. The reticle is actually etched on the glass, which means it works battery or none. Which is to say, useless.Ī prism, for lack of a better term, is built like a 1x scope. If you have no battery juice, your optic becomes a very expensive monocular with no magnification. They are tough, and the batteries do last a long time, but ultimately they are reliant on electronic power. What we commonly call a red dot is an electronic projection of a laser or light on a piece of glass. The difference between a Prism and an electronic red dot is significant. Prisms, in my opinion, are the weapon of choice for dire survival situations. That being said, I jumped at the chance to cover the new SLx MicroPrism. This means I can tell you now that it has held up magnificently and is well worth the money. This means it has had almost daily use since, as I had a range in my backyard for most of 2020/21. I kept that optic and put it on one of my training guns. And even if I had been initially skeptical of the MD-25 at a price point of $169.00, I am not now. Not only did the MD-25 perform, but it also passed odd things like a tracking test better than some $800 red dots.
