Holosun 510C - Best Overall

Why this is the hottest selling optic right now - HoloSun 510C is low drag and low weight, and it's by far the best open reflex sight for PCC at this price point. It's actually one of the best optic for Ruger PC carbine on our last PCC accessory guide.

Find Target Fast - Instantly place the dot on the target while shooting on the move or transitioning with both eyes open thanks to the large viewing window that doesn't obstruct shooter's view.

Works For Cross Eye Dominant Shooters - Still have room to cheek weld using non dominant eye 

No Sight Alignment Needed - Parallax free reticle stays on target accurately even if the shooter's eye shifts off center horizontally or vertically.

Versatile Reticle System - Large CQB 65 MOA reticle circle for range estimation, perfect for accurate close-range shooting with a rapid holdover reference point

Trijicon MRO - Largest FOV

Trijicon MRO on CZ Scorpion

Why shooters love the MRO - Similar to the Aimpoint Micro, but it's a large window red dot sight with a bigger field of view, and at a cheaper price point. 

Reduced Tube Effect - The tapered body design allows the tube to remain small while giving the shooter a wide view.

Reduced View Obstruction - 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 ergonomical for lefties and righties.

Battle Proven Durability - The 7075 T6 aluminum body is as tough as a little tank.  Handle rough handling, drops, recoils and kicks like its nothing!

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.

Why this legacy optic still rocks - The C-More red dot is one of the best 9mm carbine in the past, and it still is today. It's very unique looking optic that race competition shooters love.  

Available both Aluminum or Polymer body for a super lightweight configuration specifically designed for fast action shooting, and it accepts direct mounting for custom and Aftermarket mounts.

Wider FOV For Faster Shooting - Increase target acquisition speed with this 29mm large circular profiled Heads-up-display to instantly place the dot on the target while shooting on the move or transitioning, without an unobstructed field of view.

Retain Zero For Better Accuracy - Maintain zero relies on the quality of the optic and the tightness of the windage and elevation adjustment screws, using positive locking screws from both sides to 4X the tightness and rigidity for handling largest caliber to full auto fire

Multi-Application Usage - Dot size selection is important for distance and close-range shooting, pick from 2 MOA all the way to 16 MOA dot size for a wide range of shooting applications including hitting targets over 50 yards

Trijicon SRO - Best Lightweight Red Dot Sight

Why we picked this one - The Trijicon SRO feels just like an Holosun 510C but much smaller and lighter for a high speed low drag pistol caliber carbine like the MP5, MPX and many others

Easier Battery Access - Load/Replace battery right from the top! No sight removal or re-zero required

Better Follow Up - Increased sight acquisition speed including consistent fast follow-up shots without losing the dot inside the window even if the eye is slightly off center.

Bushnell TRS 25 - Best Budget Optic


Why we picked this for the new gun owners - The TRS 25 is super affordable for new gun owners. The new model has multiple improvements in several important areas, which include shockproof construction that can withstand bumps, drops and rough handling.

The waterproof construction can handle water immersion and its Nitrogen purged fog-proof coating fight against humidity or rapid temperature change in the field, so you don't have to worry about the sight fogging up.

Wait...There is more...

Now the battery lasts over 50,000 hours and delivers a brighter, rugged sight in a compact package.

What To Look For

MOA Reticle Dot Sizes

68 MOA reticle at night

Between 3 MOA - 6 MOA are recommended for fast CQB actions and competitions.

For shooting competitions, most targets will be placed at about 10 – 25 yards. Some matches have targets placed at 50- 80 yards.

The BIGGER the dot the EASIER it is for the eyes to acquire and the cleaner the dot is for shooters with astigmatism.

The size of the dot also allows the shooter to track it better through recoil. Since the shooters shoulder their PCC, it shouldn’t be a problem.

Long Battery Life

As red dot technology improves, the battery life on these bad boys are getting ridiculously long - near infinite!

No worry if you forgot to turn it off!

If you hate the battery running out every so often after a range trip, please be sure to pick an optic with at least 50,000 - 100,000 hours battery, which most reflex sights on the market today have that capability.

In addition, solar fail-safe and motion activated sights from Holosun Optics are also very popular because they just never die.  

Enclosed Emitter VS. Open Emitter 

Full body red dot sights vs open emitter red dot sights

Should you pick an open emitter optic or an enclosed emitter?

An enclosed emitter will be the best option to protect the lens and emitter from dust and water, and making it full weather proof.

An open emitter sight can't defend against dust, moisture, water, or debris. Anything can get in there and completely obstruct the reticle projection.

If you like the Trijicon RMR, Holosun 510C are your favorite sights, but you would like more protection. Maybe consider Holosun 512 and Aimpoint ACRO P-1

Double Red Dot Setup Necessary?

Many people ask: “Why do some of these competition shooters run dual red dot optics on their setup?”

“What are the advantages?”

The simple answer is that the shooters can get shoot around barricades much easier with their offset angled sight for faster transitions and hard leans to the left or right.

When they are done, they transition to the upright optic.

It's not completely necessary, but it gives the shooter several advantages:

  • It’s comfortable to tilt the gun and have something to aim with
  • Keeps the barrel align with the offset red dot optic for accurate angled shooting
  • Shoot over barriers & have the dot right in the window
