This is the Vortex Strikefire II red/green dot rifle optic. My dad owns the one you see pictured and I’ve used it myself. Here are my thoughts about the Strikefire II, occasionally compared to an EoTech XPS and an Aimpoint Comp M4/CCO/M68, as these are what I have owned and used downrange.
Price: I’ve posted the link above for the optic priced at $200. This price is more than fair for what you’re getting in my opinion. You’ll still be paying around $550 for the more well known, “higher end” optics like the EoTech XPS line and the Aimpoint CCO. I love both of those pieces, I own the EoTech and I had the Aimpoint in Korea, Germany and Afghanistan. Both are great, but you pay for it. The Strikefire is much more affordable and I have been impressed with the value.
Vision: The red/green dot is 4 MOA, as opposed to the 1 MOA red center dot on my EoTech. The Aimpoint CCO is 2 MOA, if I recall. Honestly, I think 4 MOA is plenty acceptable for the work we have ahead of us. The red/green dot is easily toggled and each color has ten brightness settings controlled by two buttons. This is not a scope, so there is no magnification.
Ergonomics: I’m pretty happy with the ergonomics, but this essentially just speaks to where the control buttons are located. You’ll have two buttons on the left side of the optic, one is an up arrow, the other is down. Press either one to turn the dot on, press the up button to brighten, the down button to dim. Hold the bottom button until the color changes to toggle between green and red. Hold the top button to shut it off. Simple, and I love that the buttons are easy to access. My EoTech buttons are similar, but they’re located in the center low near the rail. I have a G33 magnifier behind my XPS, so the buttons can be hard to press. Also, the optic sits high enough (but not too high) that there is no need for risers or spacers.
Zero: This optic has held the zero quite well. No major adjustments over the lifetime so far, only one minor adjustment. There is a 100 MOA adjustment range and each click is 1/2 MOA. Four of us were scoring hits at 300 yards in clear weather using 62gr ammo.
Rugged: The Strikefire is water resistant but not waterproof. Rain is fine, but don’t put it underwater. It is shockproof, which is a must for any combat rifle optic.
Misc: Use two eyes to aim, this thing is large enough for it. Cowitnessing is easy with Magpul BUIS. Length is 5.6 inches and it weighs 7.2oz. Using a CR2 battery, you’re supposed to be able to get a maximum of 600 hours of life at optimum temps.
My recommendation is that if you don’t have the money to purchase something like the Aimpoint Comp M4, you can pick up the Strikefire II from Vortex and you will be more than good to go.
