The HoloSun 510C is the ultimate open reflex sight for PCC enthusiasts. This cutting-edge optic is taking the market by storm, and for good reason. Its low drag and lightweight design make it perfect for fast-moving, action-packed situations.

Are you in the market for a reliable, high-performing red dot sight? Look no further than the MRO. This sight is a favorite among shooters for its large window and wide field of view - similar to the Aimpoint Micro, but at a more affordable 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 built to withstand rough handling, drops, recoil and kicks, making it a perfect choice for anyone who wants a battle-proven durable optic.

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

We chose the Trijicon SRO for its high speed, low drag performance on pistol caliber carbines like the MP5, MPX and others. It offers a similar feel to the Holosun 510C but in a much smaller and lighter package.

Bigger Window  - Get on target faster compared to the original Trijicon RMR on pistol applications, and it's gonna do the same on PCC even better when you can shoulder the gun!

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.

Burris FastFire 3 - Best Budget Optic

burris fast fire 3

if you want to take your PCC to the next level, you need the Burris FastFire 3. This micro red dot sight is a favorite among competition shooters and for good reason also as an offset red dot sight.

With options of 3 MOA, 8 MOA, and even a larger size for shooters with astigmatism, the FastFire 3 gives you the flexibility to match your specific shooting needs.

But the best part about this sight is its weight, or lack thereof! The FastFire 3 is one of the lightest in its class, barely adding any weight to your firearm, making it easy to quickly acquire and track targets.

The auto-brightness control system adjusts to match the ambient light ensuring that the reticle remains bright and easy to see, no matter the lighting conditions. And talk about built to last, the FastFire 3's battery can last up to 5 years. It's considered one of the most cost-effective open emitter reflex optics for pistol use on the market today. 

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.

In shooting competitions, target placement typically ranges from 10 to 25 yards, and some matches may even have targets placed at 50 to 80 yards.

For easier target acquisition and improved shooting accuracy, especially for those with astigmatism, a larger dot is recommended.

Additionally, a bigger dot size allows shooters to track the dot better through recoil, especially when shooting with PCC. Targeting with a PCC shouldn't be an issue with a bigger dot.

Long Battery Life

Red dot technology is improving, and as a result, battery life on these optics are becoming absurdly long, nearly infinite.

No need to worry about forgetting to turn it off after a range trip.

If battery life is a concern for you, we recommend choosing an optic with a battery life of at least 50,000 to 100,000 hours, as most reflex sights on the market today have that capability.

Holosun Optics has become very popular as well, particularly for their solar fail-safe and motion activated sights which are known for their longevity and never die.

Enclosed Emitter VS. Open Emitter

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.
