Sig Sauer ROMEO 5 - Best Budget Option
Get this if on a budget - The ROMEO5 is a robust, compact red dot optic offering from Sig Sauer. It's ultra-low parallax so the point-of-aim is the point-of-impact and the red dot remains parallel to the bore of the firearm.
2 MOA dot size with 10 illumination settings including 2-night vision works extremely well in all light conditions.
It uses 1 CR2032 battery that runs up to 40,000 hours, and the cool part is it has the same motion-activated reticle like the HoloSun for battery consumption and longevity.
Also accepts standard Aimpoint Micro aftermarket mounts
Trijicon MRO - Best FOV Sight
Why large FOV matters for most shooters - The Trijicon Miniature Rifle Optic has the largest field of view among other tube style red dot optics for max situational awareness.
One thing unique about the design is that the brightness adjustment is on the top of the optic, which eliminates view obstruction on the sides, and it also made it ergonomic for lefties and righties.
The tapered body design allows the tube to remain small while giving the shooter a wide view.
The optic is built with 7075 T6 aluminum alloy, the toughest material the industry has to offer, which can withstand a lot of rough handling especially if you like to run your gun hard.
What people think of the MRO - In the past, people if anything like this exist it will fly off the shelf almost immediately because Aimpoint Micro cornered the market.
Not only this sight is featured on the MPX in the movie John Wick, in real life, but the Trijicon MRO is also a good option for anyone who just getting started with the shooting.

Common FAQ
How Is The John Wick Sig MPX Configured
The SIG MPX was on steroid in the 3rd John Wick movie. Without spoiling the movie you can check it out here.
Even though it was just a movie, they portrait the gun very realistically and it was very enticing for people to buy what they see in the movie.
Large POV Trijicon MRO set up with the lower 1/3 Giessele Super Precision mount gives more eye box and also prevent the TLR-8 from obstructing the field of view.
In the movie, John blasted multiple bad guys with the TLR 8 green laser sight turned on. However, in real life aiming through the red dot sight is way more practical.
Where Is The Best Optic Mounting Spot on The MPX
The optimal spots to mount an optic on the Sig MPX top receiver is the distance between the trigger guard to where to ejection port is.
The closer you mount the sight with a large field of view optic, the faster you can pick up the sight and you have a larger eye box to work with.
The Sig MPX is a well-balanced sub-gun. Whether you're using an SBR, pistol or full-length carbine. Mounting a lightweight optic doesn't affect the weight balance or handling whatsoever.
What Co-Witness Height Works The Best On The MPX?
Where you cheek weld the MPX is similar to an AR15 or the Sig MCX. An absolute co-witness height will do the job, but a 1/3 or lower 1/3 mount height gives you a bit extra room for eye box comfort.
I personally like to use the lower 1/3 co-witness mount for my MPX.
What's The Best Magnifier For The MPX
A 9mm PCC isn't designed for reaching long distances, however, a 9mm can reach as far as 100 yards and still be very accurate.
Putting an ACOG or a magnified low power variable scope isn't necessary, instead, we recommend using a red dot sight magnifier like the Sig Sauer JULIET4 for more zoom.
