1. Sig Sauer SOR52001 Romeo5 1x20mm Red Dot Sight

We briefly talked about how Sig Sauer is also known for their optics. There wasn’t a better way of starting the list. I present you Sig Sauer Romeo. One of the most loved red dot sight on the market.

Romeo is a 1x red dot optic compatible with Sig MPX. The housing of this sight is created from aluminum. To ensure the durability of the housing, it has an anodized matte finish on top of it. Lenses used on this scope are also fully multi-coated.

It’s water, fog, and shockproof all at the same time. Not a lot of optics can claim to have all those, but this one does. While it’s not submergible, it can take a bit of bad weather head-on. The lenses are clear under all weather as well. It still isn’t suitable for night-time hunting. But you can pair it with a magnifier.

The base magnification of the sight is 1x and the objective lens is 20mm. It gathers plenty of light for you to work with.

The height with the included mount is just perfect. If you are using this on an MPX, you don’t need to increase the height or buy an additional riser.

Earlier I mentioned you could add a magnifier and NVD. You can certainly do that. If you want to increase the magnification to 3x to make better use of the MPX, you can certainly do that. It’s a great sight for a magnifier.

How To Choose The Best Sight For Sig MPX

MPX is a submachine gun, not an AR. That’s why, we should purchase sights or optics that are capable of doing short to mid-range shooting. We don’t want to purchase a riflescope that might not even fit on the gun.

Build Quality

SMGs are used in security firms and gun ranges. In both cases, you might face bad weather or just a straight-up rainstorm. You don’t want your sight to die on you in those dire situations. That’s why, having a sight that is built like a tank is always a good idea.

Lens Quality

Lenses are the most important part of an optic. If they are not clear, your vision won’t be clear. On top of that, a lot of you use glasses while shooting. In that regard, the lens just has to be clear. Or else you will have a hard time justifying the purchase of a sight.


MPX is a lightweight gun. If you are adding a sight, then make sure it’s a lightweight sight as well. If you are also planning to put an NVD or a magnifier, then you have to make sure it’s a lightweight setup. You don’t want to make the top crowded.


There are plenty of sights compatible with Sig MPX. But all of them are not good or worthy of deserving attention. These are some of the best sights on the market for any guns in question. Luckily, they are also suitable for MPX. A huge plus if you ask me.

Take whichever you want from the list and you will be a happy camper. Good luck with further endeavors. Till next time, stay tuned for more reviews.
