Sig Sauer ROMEO5

The Sig ROMEO5 is much more affordable than all the optics we have recommended in this post, and it’s one of the best selling Sig Sauer red dot optics everywhere you go.

The new line of ROMEO series red dot can also accept aftermarket mounts from American Defense, Scalarworks and more. Basically it accepts Aimpoint Micro mounts for increased mount durability.

What makes the ROMEO5 stands out is it’s MOTAC system, which dramatically increases battery life by shutting it down when not in use, and it instantly activates the reticle when it senses motion.

With a total of 40K hours battery using just 1 CR2032 battery is very impressive. For the price point, the Sig ROMEO5 is the perfect Aimpoint alike optic for the MP5 with its robust and compact design.

Sig Sauer SOR52001 Romeo5 1x20mm Compact 2 Moa Red Dot Sight, Black
  • 2 MOA Red-Dot provides 10 illumination settings (8 daylight plus 2 NV) for visibility in all light conditions
  • MOTAC (Motion Activated Illumination) powers up when it senses motion and powers down when it does not. Provides for optimum operational safety and enhanced 40,000+ hour battery life
  • Integrated M1913 Picatinny interface provides industry-standard mounting options for a wide range of applications
  • Dependable waterproof (IPX-7 rated for complete water immersion up to 1 meter) and fog-proof performance

Trijicon SRO / RMR

The Trijicon RMR is the gold standard of micro red dot optic, when mounted on the MP5, it has the slimmest optic profile for CQB use.

Now… The NEW Trijicon SRO has been released with a much bigger lens originally designed for pistol shooters for better dot tracking, but it totally works on the MP5.

HK sp5k with trijicon SRO

The optic profile is the same as the RMR, so you can use any of your existing RMR optic mount, and the only big differences are the bigger lens for better target acquisition, better dot tracking, and easier battery installation with top loading design.

Besides that, the Trijicon SRO has the same durability as the RMR, super lightweight and slim for MP5 and other PDW guns.

Trijicon SRO Sight Adjustable LED 2.5 MOA Red Dot, Black
  • LARGE, UNOBSTRUCTIVE FIELD OF VIEW: Parallax-free and compatible with suppressor-height iron sights
  • CLEAR, CRISP DOT: Fine-tuned, illuminated reticle, coupled with exceptionally clear front lens, offers a clear sight picture with a crisp 2.5 MOA Red Dot
  • EASY, ADJUSTABLE WINDAGE & ELEVATION: Tool-less design makes zeroing hassle-free
  • RED DOT PISTOL READY: Designed to fit on many of the most popular red-dot-ready brands on the market (mount not included)

Aimpoint Micro

The Aimpoint Micro is the oldest kid on the block. It’s tough, durable and many Tier 1 units around the World use it.

The most cutting edge features on the Aimpoint Micro is it’s battery life and ruggedness in a super compact size. Field tested to survive combat related abuse, which other budget optics can’t.

It’s improved lens clarity, shockproof performance, and parallax free reticle has deems itself the ultimate go-to war optic for many PDW, PCC and fighting rifles.

It’s the ultimate bomb-proof red dot sight on the market for many years and it’s not cheap. For those who have been pushing it off from buying this optic for years, maybe this is the right time to finally get it for the MP5.

Aimpoint Micro H-2 Red Dot Reflex Sight with Standard Mount - 2 MOA - 200185
  • Advanced objective lens system for better light transmission and unmatched optical clarity
  • 2 MOA dot with 12 settings for low light and daylight brightness
  • Standard Mount for Picatinny and Weaver Mount Included
  • Up to 5 years of continuous operation using one CR2032 battery (included)

Trijicon MRO

The Trijicon Miniature Rifle Optic is a sight on the market with a big field of view in direct competition with the Aimpoint Micro.

Its tapered body design allows the tube to remain small while giving the shooter a wide view, which eliminates view obstruction on the sides, and it also made it ergonomic for lefties and righties.

The optic is built with 7075 T6 aluminum body, 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.

For MP5 shooters, this is actually a better option than using something like the Aimpoint Micro because the field of view is so much bigger, which maximizes situational awareness for the CQB type of shooting.

For the price, the MRO is a better option for anyone just got started with shooting. If you’re new and want something as tough as the Aimpoint but without spending over $800 please check the best price by clicking on the button below.

Trijicon MRO-C-2200005 1x25mm Miniature Rifle Optic (MRO) Riflescope with 2.0 MOA Adjustable Red Dot Reticle with Full Co-Witness Mount
  • Magnification: 1x
  • Objective size: 25mm
  • Eye relief: Infinite
  • Distance From Top of Mounting Rail to Optical Axis: 1.538 inch

What To Look For?

Minimal Parallax Shift

When picking an optic for the MP5, having a minimal parallax shift is very important.

Not all reflex sights have a 100% parallax free reticle as they are advertised, usually slight horizontal or vertical shifts are noticeable at about 7 – 15 yards if your sight picture isn’t completely centered.

At Our local gun shop was kind enough to let us test over 16 different optics at the store at a reference target at 20 yards.

We narrowed down to 6 quality optics that we’re recommending, the Sig ROMEO4S has the slightest parallax shift both vertical and horizontal.

Low Profile Optics

MP5K pistol with red dot sight

The MP5 is definitely a compact gun in nature, so picking a low profile optic for it makes total sense. Our favorite is the Holosun 403R for almost being the exact copy as the Aimpoint Micro but at 1/4 the cost.

It doesn’t obstruct your view and it feels very compact when maneuvering in tight spaces.

In the past, you might have noticed tons of Aimpoint Comp or Aimpoint PRO being mounted on the MP5.

Those optics are great, but they’re bulky, narrow field of view and they’re oversized compared to what we have today.


Pick Lightweight Optics

MP5 with holosun 503GU

The MP5 weighs about 4.4 lbs without any fancy accessory, so let’s keep it light when considering adding a red dot to it. Out of the 6 products, the Holosun 403R and Sig Sauer ROMEO4S are the lightest both on average weighing just under just 7 oz with a lightweight mount.


2 – 6 MOA Dot Sizes Are Recommended

Most optics on the market by default will offer a 2 MOA dot that is popular for both target shooting and personal defense. It’s clear and precise for both close and medium-range shooting applications.

The MP5 is the 9mm sub-gun for that 15 – 100 yards targets, but pushing it to shoot 200 yards or more isn’t what we want. There is a time and place for 9mm, 40SW and 45 ACP.

3 to 6 MOA dot sizes are favorable for CQB shooters, where the reticle size is big enough to acquire and aim.


MP5 Optic Mount Options

The MP5 doesn’t come with any optic mounting platform, but most aftermarket optic base mounts will fit HK variants and the clones like the Zenith Z-5RS, Dakota Tactical, PSA, PTR and other non-mainstream local brands.

We highly recommend Checking Out on our site: Best Optic Mount For MP5

You can weld a Picatinny rail piece on the top of the receiver or add a claw mount, but one thing to make sure is to center it to the bore axis of the gun to minimize offset.

The most popular is the claw mount that goes over the top of the receiver and clamps tight on the receiver. Instead of welding a Picatinny rail adapter which requires a gunsmith, the claw mount is the easiest option.

NEW: HK Official Releases HK SP5, Watch Here.

The MP5 is still a very classic 9mm sub-gun. It’s a lot of fun shooting this thing, not to mention the cool MP5 slap is one of the coolest gun thing in the firearm culture.

Adding a lightweight and compact red dot optic makes this thing work like a champ in close range type of shooting.

Out of 6 recommended optics, the Sig Sauer ROMEO4S and Holosun 403R are the best for the MP5 for the money and performance.
