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.

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 MRO

Image Referenced Zenith Firearms

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 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.

What To Look For?

Minimal Parallax Shift

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.

Our local gun shop was kind enough to let us test over 16 different optics at the store at a reference target at 7, 20 and 50 yards.

Low Profile Optics

MP5K pistol with red dot sight

A low profile optic on an low mount works very well on the MP5 and other guns similar to the MP5.

They're light weight and not too bulky for a sub machine gun (or semi version)

The MP5 weighs about 4.4 lbs without any fancy accessory added, so let's keep it light 

What Dot Size To Get ? 2 - 6 MOA 

Most optics on the market offer a 2 MOA dot that is popular for close and medium-range shooting applications.

A 3 MOA dot is a good sweet spot option, and a 6 MOA is much bigger to pick up and it's much better for shooters with astigmatism.

For a 6 MOA optic, please check out the Trijicon RMR RM07 model, SRO and Vortex Venom

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.

The most popular option 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.
