Holosun Optics

Gold dot, if you've not tried one, is worth a look.

The 507C X3 now comes with a gold reticle alongside the usual red. Same multi-reticle system, same solar power, same RMR footprint. The difference is what your eye does with it.

Gold sits differently against a target than red does. Some shooters find it pops cleaner in bright light and washes out less against pale backgrounds. Not better, just different, and if red's never quite sat right for you it's worth the experiment.

In stock now alongside the red 507C X3 and the single-reticle 407C X3.

New on the shelf: the Holosun X3 generation has landed.

407C X3, 507C X3 in red, and the 507C X3 in gold. All solar powered, all 2 MOA, all the reliability you'd expect from Holosun's flagship pistol footprint.

The 407C keeps it simple: one clean 2 MOA dot, nothing to fiddle with. The 507C gives you the multi-reticle system, so you can run the 2 MOA dot on its own or drop it inside the 32 MOA circle when you want a faster pickup. Same optic, two ways to shoot it.

Solar failsafe means it'll keep running off daylight if the battery ever taps out. Shake Awake keeps it asleep in the safe and wake the moment you pick it up.

Built for IPSC, PCC, mini rifle, Action Air. In stock now.

The optic that surprised a lot of shooters.

The AEMS packs a large field of view into a compact footprint, making it a favourite for practical rifle, gallery rifle and sporting setups.

Add Solar Failsafe, Shake Awake and impressive battery life, and it’s easy to see why it’s become one of Holosun’s most talked-about optics.

One of the biggest advantages of Holosun’s Multi-Reticle System is being able to choose the sight picture that works best for you.

Some shooters prefer the speed of the 65 MOA circle with centre dot.

Others switch straight to the dot for a cleaner sight picture at distance.

The beauty is having the choice available when you need it.

Which reticle are you running most often?

🔴 Circle-dot
🔴 Dot only

When did you last actually change the battery in your Holosun?

Genuine question. Between Shake Awake powering the thing down when it's not moving, Solar Failsafe topping it up off daylight, and battery life measured in tens of thousands of hours, plenty of people genuinely can't remember.

So go on, when did you last swap it? Or have you simply forgotten it takes one?

Here's the question that trips up more first-time red dot buyers than any other: "will it actually fit?"

Optics mount to a "footprint", the pattern of screw holes and recoil lugs on the bottom of the sight. Get the footprint right and it bolts straight on. Get it wrong and you're hunting for adapter plates.

A quick guide to the common Holosun ones:

The 407C / 507C footprint is the workhorse, found on a huge range of pistol cuts and rifle mounts. The 509T uses its own dedicated footprint, designed to lock in tight under recoil. The RMSc footprint is the slim one, used by micro sights like the 507K and EPS Carry where a smaller, lower-profile optic suits the build. And rifle-first sights like the ARO and AEMS come with their own mounts built for a standard Picatinny rail.

The short version: check what your slide is cut for, or what rail you're mounting to, before you buy. If you're not sure, drop us a message and we'll point you at the right one.

What are you mounting, and what footprint is it cut for?

The HE407C-GR X2 is the one we'd point a lot of first-time buyers towards, and it's not hard to see why.

It's a compact open reflex sight with a clean 2 MOA green dot. No clutter, no menu-diving, just a crisp aiming point that's quick to pick up. And green is the clever bit here: the human eye is more sensitive to green light than red, so for a lot of shooters the dot looks brighter and sharper in daylight at the same power draw. If you've ever squinted at a washed-out red dot on a bright morning, you'll appreciate the difference.

Solar Failsafe keeps the dot lit off ambient light, so even if the battery picks the worst possible moment to die, you're still in the game. Shake Awake powers it down when it's sitting still and brings it straight back the instant you pick the gun up.
Compact footprint, so it sits happily on a pistol, an LBP, or a tidy little rifle setup.

Green dot or red, what's your preference?

What brightness setting do you actually run your Holosun on?

Be honest. Some of us crank it to full and never touch it again. Some of us sit at setting 4 and feel very pleased with ourselves. And there's always one who insists the dot is "too bright at any setting".

What's your number, and what are you running it on?

The HE512T-GR doesn't get talked about as much as the 510C, which is a shame because it's arguably the more interesting sight.

It's a tube-style red dot rather than an open reflex. That means a sealed housing, no exposed emitter, and a more traditional sight picture if you've come from magnified optics or older tube dots. Inside that titanium housing you've got the full Multi-Reticle System (2 MOA dot, 65 MOA circle, or both), Solar Failsafe so the dot stays on even if the battery quits mid-day, and Shake Awake to put it to sleep when it's not moving.

And it's green. Genuinely useful in the kind of dappled, bright spring light we've got at the moment, where a red dot can wash out against a busy background.

It sits at the top of the tube-dot range, but you're getting titanium construction, a sealed enclosed design, and three reticles in one. Optics at this spec from other brands sit comfortably north of a grand.

Worth a look if you want something tougher than a typical open reflex without the bulk of a magnified scope.

There's a long-running debate in the optics world: red dot with a magnifier behind it, or just buy an LPVO and be done with it.
Both have their place.

An LPVO gives you a true variable scope at any zoom point in the range and a finer reticle for precision work. A red dot plus flip-to-side magnifier gives you a faster sight picture at 1x, near-instant transitions, and the option to leave the magnifier off the rifle entirely when you don't need it. Different jobs, different tools.

The Holosun HS510C with HM3X magnifier combo in FDE has just landed in stock, and it's a setup we've sold a lot of, for good reason. The HS510C is an open reflex sight with the multi-reticle system (2 MOA dot, 65 MOA circle, or both), titanium hood, solar back-up and a battery life that's frankly silly at 50,000 hours. Pair it with the HM3X flip magnifier and you've got CQB speed plus 3x reach when you need it. Comes with a hardcase.

Worth a look if you're running a PCC, mini rifle, or anything where transitioning between close and mid-range targets matters.

Red dot and magnifier, or LPVO? What's on your rifle and what made you go that way?
