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?

Taran Tactical Sig MPX with Trijicon MRO and TLR 8
Buy This On Brownells

Even though it was just a movie, the MPX is very enticing in the movie.

Large POV Trijicon MRO setup with a lower 1/3 Giessele Super Precision MRO mount gives more eye box.  As far as the TLR8, it's actually not a practical setup because the shooter can't activate the light easily. 

In fact, a dedicated scout light is better. Click here to see more weapon lights
