Taran Tactical Sig MPX Setup

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.



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.

Lower 1/3 Co-Witness Works The Best

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.


Magnifier For The MPX

Magnified JULIET4 optics for Sig 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.

Other MPX Optic Recommendations

The Sig MPX is an awesome 9mm sub-gun with features that feels like an AR rifle. Perfect for competition as well as military and law-enforcement applications.

For competition shooting, you can run a dual optics setup for faster transition while doing hard leans while shooting between barricades.

A Vortex Venom or the Sig ROMEO1 micro-optics would work just fine on a 30-degree angled offset mount to align with the bore to compensate the height overbore distance.
