Best Holosun Red Dots (2026): 507 Comp, SCS, EPS & More

The best Holosun red dots are a big reason pistol optics went mainstream. Holosun took features that used to cost extra, like solar backup, shake awake, side-loading batteries and multiple reticles, and put them on optics that working people can afford. The problem is the model numbers. 407, 507, 508, 509, K, C, X2, Comp, SCS, EPS: it reads like a parts catalog.

Our reviewers at GunsAmerica Digest have run a lot of these dots hard. One put more than a thousand rounds of full-power buckshot through a 507C on a Benelli M4 without a blink. Another ran a 507 Comp in USPSA on a Glock 45 for more than six months. Another put an SCS on a 10mm Glock 20, dunked it in water and broke a mounting screw along the way, which we will get to.

This 2026 guide picks the Holosun dot that fits each job, from full-size pistols and micro carry guns to ARs, PCCs and shotguns. For brand-versus-brand comparisons, see our best pistol red dots and best AR-15 red dots.

Buyer’s Guide: How To Choose The Best Holosun Red Dots In 2026

Holosun red dots share a lot of technology, so the decision mostly comes down to footprint, emitter design and reticle.

Footprint Comes First

A pistol dot has to fit your slide. The 407C, 507C and 507 Comp use the Trijicon RMR footprint, the most common pistol cut. The 407K and 507K use a smaller K footprint for micro pistols like the Glock 43X and SIG P365, and our 407K reviewer warned that the two cuts are not interchangeable. The EPS uses the K footprint, and the SCS line is built for specific slides like the Glock MOS. Check your slide before you buy, and budget for a plate if needed.

Open Or Enclosed Emitter

Open emitter dots like the 507C are lighter and lower, but rain, lint and mud can block the emitter. Enclosed dots like the EPS and the HS512C seal it off. Our EPS reviewer said the closed emitter keeps his sight picture clear of obstructions on an everyday carry gun, at a cost of about $100 over the 407 series at the time of review.

Dot, Circle Or Both

Holosun’s multi-reticle system lets you switch between a dot, a circle and a circle-dot. The 32 MOA ring on the 507C is great for patterning buckshot, and the 65 MOA circle on the AEMS and HS512C works as a quick range estimator. Some shooters hate the busy reticle. Our 407K reviewer prefers a simple 6 MOA dot and argued you do not need a 2 MOA dot for pistol accuracy. Pick the reticle you will actually use under stress.

Red Or Green

Green dots are easier for some eyes to see. Our 407K reviewer shot red and green side by side in the Arizona sun and found both equally easy to see. It comes down to your eyes, and green models often cost a bit more.

Power: Battery, Solar And Shake Awake

Most Holosun dots run a coin battery for tens of thousands of hours, with solar assist and shake awake to stretch it. The SCS line goes further, with a solar cell charging a sealed internal battery, so you never change one. Side or top battery access means you can swap a battery without pulling the optic and losing zero.

Rifles, PCCs And Shotguns

For long guns, the AEMS and HS512C give you bigger windows and higher mounts for co-witness. If you are setting up a pistol caliber carbine, our best PCC optics guide covers more choices.

Best Holosun Red Dots Ranked: 2026 Product Roundup

Holosun 507 Comp: Best Overall Holosun Red Dot For Full-Size Pistols (2026)

The Holosun 507 Comp is the best overall Holosun red dot for full-size pistols because it adds a bigger, taller window and eight reticle choices to the proven RMR footprint. Our reviewer, who shot USPSA for more than a decade, ran it in competition on a Glock 45 MOS for more than six months and called it a big improvement.

Read our full Holosun 507 Comp review here.

He switched reticles between stages, using the 8 MOA circle on stages with targets past 20 yards. The taller window makes it harder for the dot to fall off the glass under recoil, and the wider window helps if the gun is not straight on the draw, a common problem for newer dot shooters. He summed it up as a large lens, eight reticle choices, good battery life and a reasonable price: $435 MSRP with a common street price of $369 at the time of review in 2024.

Key Specs

• Footprint: Trijicon RMR
• Reticle: 2 MOA dot and 8, 20 or 32 MOA circle (eight combinations)
• Window: 1.1 x 0.87 in
• Weight: 1.7 oz
• Housing: 7075 T6 aluminum
• Adjustment: 1 MOA per click
• Water rating: IP67
• Price: $435 MSRP, $369 street at the time of review (2024)

Pros

• Bigger, taller window
• Eight reticle choices
• Common RMR footprint
• Six months of match use

Cons

Holosun SCS: Best Holosun Red Dot For No Battery Changes (2026)

The Holosun SCS is the best Holosun red dot for shooters who never want to change a battery, because a solar cell charges a sealed internal battery and the optic mounts directly to slides like the Glock MOS without an adapter plate. Our 2026 reviewer tested the SCS MOS on a 10mm Glock 20 and called it the easy button for pistol optics.

Read our full Holosun SCS review here.

He was honest about the problems. He sheared a mounting screw before finishing his first magazine, the brightness is automatic and can feel about two levels too bright, and the reticle came only in green. It still held up to 10mm recoil and a dunk in water, and MSRP was $412 at the time of review. For micro pistols with an RMSc cut, our earlier SCS Carry review found the same no-battery concept in a 1.05 ounce package, listed at $470 MSRP and about $400 street in 2024.

Key Specs

• Mounting: direct to Glock MOS (other models for PDP 2.0, P320, VP9, M&P 2.0); SCS Carry uses RMSc
• Reticles: 2 MOA dot, 32 MOA circle, or both (green)
• Power: solar cell charging a sealed internal battery, up to 20,000 hours
• Housing: Grade 5 titanium (SCS MOS)
• Water rating: IP68
• Price: $412 MSRP at the time of review (2026)

Pros

• No battery changes
• Direct Glock MOS fit, no plate
• Low enough for stock sights
• Survived 10mm recoil and water

Cons

• Sheared a mounting screw in testing
• Brightness not user adjustable
• Green only at the time of review

Holosun EPS: Best Enclosed Holosun Red Dot For Carry (2026)

The Holosun EPS is the best enclosed Holosun red dot for carry because it seals the emitter in a small, low housing that fits an everyday carry gun. Our reviewer replaced a 407C on his Glock 19 MOS with a 6 MOA EPS, using an adapter plate because it uses the Holosun K footprint.

Read our full Holosun EPS review here.

It was easy to zero at 15 yards with 1.5 MOA adjustments, the top of the optic sits less than an inch above the slide, and the CR1620 battery is rated at 50,000 hours and changes from a side port without losing zero. He called it a great size for EDC and a great addition to the line. The $390 MSRP was about $100 more than the 407 series at the time of review in 2022. It also comes in 2 MOA and circle-dot.

Key Specs

• Type: enclosed emitter
• Footprint: Holosun K
• Reticle: 6 MOA dot (2 MOA and circle-dot also offered)
• Adjustment: 1.5 MOA
• Battery: CR1620, side loading, rated 50,000 hours
• Water rating: IPX8
• Price: $390 MSRP at the time of review (2022)

Pros

• Enclosed emitter
• Small and low for carry
• Side battery access
• Shake awake

Cons

• K footprint needs a plate on many slides
• Costs more than the 407 series

Holosun 407K: Best Holosun Red Dot For Micro Pistols (2026)

The Holosun 407K is the best Holosun red dot for micro pistols because it gives slimline guns a clean, simple 6 MOA dot at a lower price than the 507K. Our reviewer, a red dot shooter since the mid-1990s, cannot stand busy reticles on a carry gun, and the 407K’s plain dot was exactly what he wanted.

Read our full Holosun 407K review here.

He had his slides cut and tested both the red and green versions. With the dot he hit 8 inch plates at 30 yards more than 80 percent of the time, compared with about 45 percent on irons. He expected the green dot to wash out in the Arizona sun, and it did not, but he found it neither better nor worse than red. MSRP was $258 for red and $276 for green at the time of review in 2021.

Key Specs

• Footprint: Holosun K (micro pistols)
• Reticle: 6 MOA dot
• Colors: red or green
• Price: $258 red, $276 green MSRP at the time of review (2021)

Pros

• Clean 6 MOA dot
• Fits micro pistols
• Costs less than 507K
• Red or green

Holosun 507C: Best Holosun Red Dot For Shotguns (2026)

The Holosun 507C is the best Holosun red dot for shotguns because its 32 MOA ring lets you see your buckshot pattern and it shrugs off heavy recoil. Our reviewer mounted it on a Benelli M4 with a Scalarworks mount and patterned Federal FliteControl 8 pellet buckshot at 5, 7, 10 and 15 yards. Every pattern stayed inside the 32 MOA ring.

Read our full Holosun 507C review here.

He was more than a thousand rounds deep with the 507C on that M4, and it never blinked. It uses the RMR footprint, runs 50,000 hours on a CR1632 battery with solar backup and shake awake, and has big buttons for brightness and reticle changes. The glass has a noticeable blue tint, which he did not find distracting. If you are new to pistol dots, our 507C ACSS Vulcan review explains how its chevron reticle helps you stop fishing for the dot.

Key Specs

• Footprint: Trijicon RMR
• Reticles: 2 MOA dot, 32 MOA ring, or both
• Battery: CR1632, rated 50,000 hours, solar backup
• Adjustment: 1 MOA
• Features: shake awake, side battery

Pros

• More than 1,000 rounds of buckshot without a blink
• 32 MOA ring for patterning
• RMR footprint
• Solar backup

Cons

• Blue tint
• Open emitter
• Older review

Holosun AEMS: Best Holosun Red Dot For ARs And PCCs (2026)

The Holosun AEMS is the best Holosun red dot for ARs and PCCs because its square window gives you a wide field of view in a 3.9 ounce optic that is much smaller and lighter than other 30 mm class dots. Our reviewer called it one of the best red dots for your AR.

Read our full Holosun AEMS review here.

He ran it on an S&W M&P 12 shotgun, a Ruger PC Charger and a JP5 9mm PCC, and zeroed it three times on three guns with no trouble. The 2 MOA dot and 65 MOA circle made 9mm holdover easy, and when a man-sized target fills the circle top to bottom, it is at about 100 yards. A top solar panel and side battery compartment round it out, and it comes in red or green.

Key Specs

• Window: 1.1 x 0.87 in
• Reticles: 2 MOA dot, 65 MOA circle, or both
• Weight: 3.9 oz
• Power: battery with solar backup, side battery access
• Colors: red or green

Pros

• Wide window in a small body
• Easy zero on three different guns
• 65 MOA circle for ranging and holdover
• Solar backup

Cons

• Proprietary mount
• No price given in our review

Holosun HS512C: Best Holosun Enclosed Rifle Dot (2026)

The Holosun HS512C is the best Holosun enclosed rifle dot because its hood protects the window on a duty or home defense carbine, and its integrated mount puts it at AR height for an easy co-witness. It weighs 8.1 ounces, which our reviewer noted is heavier than most compact dots.

Read our full Holosun HS512C review here.

He zeroed it at 50 and 200 yards and rang a 4 inch gong at 25 and 50 yards, then hit 8 and 10 inch gongs over and over at 100 yards. A CR2032 is rated at 50,000 hours, backed by two solar panels and motion-activated shutoff, and the window measures 0.91 by 1.26 inches. His complaints were an elevation turret he did not like, extra weight and the hood’s frame cutting peripheral vision.

Key Specs

• Type: hooded reflex with integrated mount
• Reticles: 2 MOA dot, 65 MOA circle, or both
• Weight: 8.1 oz
• Length: 3.35 in
• Window: 0.91 x 1.26 in
• Battery: CR2032, rated 50,000 hours, dual solar panels

Pros

• Protected window
• AR height co-witness
• Solar and motion shutoff
• 100 yard hits on small gongs

Cons

• 8.1 oz
• Reviewer disliked the elevation turret
• Hood limits peripheral vision

Holosun IRIS-GR3: Best Holosun Laser To Pair With Your Dot (2026)

The Holosun IRIS-GR3 is not a red dot, but it is the Holosun many night vision shooters add next, so it earns a bonus spot. It packs a green visible laser, an IR laser and a 60 mW VCSEL IR illuminator into a compact 6.4 ounce housing that keeps rails clean and sits low enough for LPVOs and standard co-witness sights.

Read our full Holosun IRIS-GR3 review here.

Our reviewer said it succeeds more often than it misses and fills a gap between budget lasers and legacy units costing much more. Co-aligned lasers make a daytime zero easy and it runs on a CR123A. Holosun listed MSRP at $1,058.81 at the time of review in 2025. His only complaints were an activation button that could be more tactile with cold hands and a tight beam indoors. A separate 2026 review of the IRIS-3 reported a $900 street price. Check federal and state rules on laser use and night hunting where you live.

Key Specs

• Visible laser: green, under 5 mW
• IR laser: 0.7 mW VCSEL
• IR illuminator: 60 mW VCSEL
• Power: 1x CR123A
• Weight: 6.4 oz
• Dimensions: 3.2 x 1.97 x 1.34 in
• Price: $1,058.81 MSRP at the time of review (2025)

Pros

• Strong 60 mW VCSEL illuminator
• Co-aligned lasers
• Compact and low
• Less than legacy brands

Cons

• Not a red dot
• Button not tactile with cold hands
• Tight beam indoors

Final Thoughts On The Best Holosun Red Dots Of 2026

The best Holosun red dot for most full-size pistols is the 507 Comp, with its bigger window and eight reticles. The SCS is the pick if you never want to change a battery, though our test sample sheared a screw. The EPS is the enclosed carry dot, the 407K is the micro pistol pick, and the 507C is the shotgun dot that took more than a thousand rounds of buckshot. On long guns, the AEMS suits ARs and PCCs and the HS512C protects its window under a hood. The IRIS-GR3 is the laser to add when you go after dark.
