Sightmark Strikon FMP

1x Micro Prism

Prism optics, especially the 1x versions, seem to be the new red dots. Everywhere you look someone is bringing out a new 1 power prism optic. I happen to be all in for this. Recently Sightmark sent me one of their new Strikon FMP 1x micro prisms. It has a few extras that its competition does not, and this makes it a great value in the prism market.

In the box with the Strikon, you will find an assortment of things. These include different height mounts, screws, an adjustment tool, a lens cover, cleaning cloth, and a kill flash (anti-reflective lens cover). The kill flash is a nice addition, as not all prisms come with them. Having the ability to choose what height mount you want is nice too. The Strikon comes with 1 spacer installed on the mount, with 2 extras in the box. This gives you 4 different mounting height options. The Strikon comes set up for a 1.54 inch centerline height. Other options include: 1.15 inch, 1,93 inch, and 2.32 inch centerline heights. I left mine at the 1.54 inch height as it works well on the AR that I mounted it to.

The Sightmark Strikon FMP uses their illuminated RTR-1 reticle. RTR stands for “Rapid Targeting Reticle”. Since the Strikon is a prism, this reticle is etched onto the glass. I like prisms for this reason, because they are clearer with my messed up eyes and work even when they are not illuminated. So if the battery dies, you can still use them unlike a standard projected style red dot optic. Speaking of my messed up eyes, the Strikon also has a diopter adjustment. This allows for you to tune the clarity of the reticle for your eye. One of the reasons the Strikon is similar to a red dot is that it uses true 1x magnification. Which basically means it has no magnification and acts like the red dots everyone is used to. The Strikon is very clear when looking through it. I was impressed with the lens quality.

Back to the Strikon’s Reticle. The RTR-1 is a segmented circle dot style MOA reticle with a couple of extras. The outer circle is 69 MOA in diameter with a short reticle line every 90 degrees. This large outer ring works great for super fast target accusation. The segments allow for less target obstruction compared to a full circle. This large circle also draws your eyes to the precise center aiming dots. Or in the Strikon’s case, a 2 MOA diamond. Sightmark uses a diamond because you can precisely aim using the top point of the diamond. Maybe not easily without a magnifier, but possible. Yes, the Strikon will work with magnifiers and back up iron sights, just like a red dot will. Below the 2 MOA diamond are two 1.15 MOA dots. These are positioned at 5 and 10 MOA. On a 16” 5.56 the 5 MOA dot would be around 350 yards, and the 10 MOA dot would be about 500 yards. On a 10.5”, these would be about 300 and 400 yards. I really like the RTR-1 reticle design.

As previously mentioned, the Strikon has an illuminated reticle. But not just any illumination, you can choose either RED or GREEN. With both of them being super daylight bright. To switch between the two, just hold down the “+” button for a few seconds. As far as brightness goes, the Strikon has 3 night vision and 9 daylight settings. So you can go from pitch black to bright sun easily.

The Strikon also has a setting for AUTO brightness, and it works way better than I thought it would. The auto brightness sensor is located at the front top of the Strikon. To switch to auto brightness just hold down the “+” and “-” buttons together for 3 seconds. The reticle then flashes to let you know that you are in auto brightness mode. To turn it off, just push one of the buttons and it goes back to manual adjustment mode. The auto brightness is pretty quick at adjusting the brightness. I tried it with a bright weapon light, in the dark, low light, and normal lighting. It seemed to adjust the reticle to a brightness that was appropriate. Even if it didn’t, the Strikon has that etched reticle that you can see in the light, or when using a light.

To go along with the illuminated reticle, the Strikon has a Shake Awake feature. As you would expect, this puts the illumination to sleep when the optic is not moving and wakes it up when motion is detected. The Strikon turns off the reticle after approximately 10 minutes of inactivity. The shake awake feature works with both the auto brightness and the manual brightness modes. Shake awake increases battery life. Because the Strikon can get super bright, this is a plus. One thing I really like about Sightmark is that they give you real world battery life, not just a single number at whatever low setting the company chooses. So, Sightmark lists the battery life of the Strikon at 100-10,000 hours of use. 100 hours on the brightest daylight setting and 10k hours on the lowest daylight brightness setting. This is all on a single 2032 battery that is easily replaceable via a side loading tray. Since the Strikon is a prism optic, if the battery does go dead, you still have the etched reticle to use.

When the Strikon FMP first got here I was not sure exactly what I was going to mount it on. I decided on a 16” 5.56 AR. This worked out well as I have been using this rifle to test out suppressors, so there wasn’t going to be any long shots with it and I needed a lighter weight optic for it. Since the Strikon, with the mount, is under 7 ounces, it was perfect. If you want any other type of mount for the Strikon, other than the supplied one, it uses an industry standard T1/T2 footprint. Because I was only using the Strikon at closer ranges, it meant I didn’t get to try out the 5 and 10 MOA dots at the ranges they were intended for. But since these dots only end up being an estimated range, I wasn’t worried about that. The auto brightness option on the Strikon was a nice addition since I would shoot in bright sunlight some days, at dusk on others, and cloud cover/rain on others. The clarity of the Strikon impressed me in all those conditions. However, the kill flash does stop a noticeable amount of light getting through the optic to your eye. So most of the time I left it off. I like having the ability to change the color of the illumination. I leave it on red, just because that is what I am used to. The Strikon FMP did everything I asked it to do, which is why I like this little micro prism.

In an ever increasing market of 1x prism optics, the Sightmark Strikon FMP does what others don’t. It has both red and green illumination. It has an optional auto brightness feature and shake awake. Plus it comes with a screw on kill flash. If you like 1x prism optics, or you are looking into them, the Sightmark Strikon FMP is worth comparing the other options to. You can always head over to Sightmark and check out the Strikon.
