Vortex StrikeFire II review: buy the red/green, they now cost the same
Our verdict: 4.5/5. Both StrikeFire II models sell for around $200 , so the red/green SF-RG-501 is the one to buy: it is the same sight as the red-only SF-BR-504 with one more option and no premium. For that money you get an enclosed, nitrogen-purged 30mm tube, a 4 MOA dot, a cantilever mount that co-witnesses on an AR, flip caps and a battery, all behind Vortex's unconditional VIP lifetime warranty. It is our best-value pick for a rifle. The honest limits: a 4 MOA dot is coarse past 100 yards, there is no motion wake, the mount uses a single clamp screw, and it will not out-duty an Aimpoint.
Owners rate it 4.7/5 across 613 verified reviews on OpticsPlanet, the deepest track record of any red dot we cover. Price verified August 18, 2026; confirm the current price on the retailer page.

What it is
The StrikeFire II is Vortex's entry rifle red dot: a 30mm aluminum tube with a 4 MOA dot, ten brightness settings whose lowest two are night-vision compatible, fully multi-coated glass, and rear-facing controls you can work with gloves on. Unlike the open-emitter micro dots people mount on pistol slides, this is an enclosed, nitrogen-purged tube, so there is no exposed emitter for mud or snow to block.
Which StrikeFire II should you buy? There are five
This trips people up, because OpticsPlanet lists five models under one name. The decision is the first two rows, and it just got simpler: the red-only and the red/green sight are the same optic and, as of our 14 August 2026 check, the same around $200 . The red/green used to carry a twenty dollar premium, so older reviews, ours included, told you to save it and take the red. At equal money that advice inverts. Take the red/green: a green reticle reads faster against woodland and brown backgrounds for some eyes, you are not obliged to use it, and it costs nothing extra. It is also the model the retailer holds in depth, while the red-only was down to a handful of units. The three kits simply add a magnifier.
| Model | Reticle | Price | Notes |
|---|---|---|---|
| SF-BR-504 | Red only | around $200 | The model this review scores. Same price as the red/green now, and the thinner of the two on stock. |
| SF-RG-501 | Red / green | around $200 | The one to buy: identical sight, same money, and you get the green option whether or not you use it. |
| SF-RG-501-KIT1 | Red / green + VMX-3T magnifier | on the retailer page | Bundles the Vortex VMX-3T flip-mount magnifier, itself one of our magnifier picks. |
| SF-RG-501-KIT2 | Red / green + Micro 3x22mm magnifier | on the retailer page | On backorder when we checked, so treat it as an order-and-wait, not a buy-today. |
| SF-RG-501-KIT3 | Red / green + Micro 6X magnifier | on the retailer page | In stock. The 6x is a lot of magnifier for a 4 MOA dot; think it through first. |
This review scores the red-only SF-BR-504, which is the model we carded, and everything in it applies equally to the red/green SF-RG-501 because they are the same sight. Note that owners who mention a green dot, including the most helpful negative review below, own the red/green variant. Thinking about a magnifier? Rather than buying a kit blind, see our best red dot magnifier guide, where the VMX-3T bundled in the first kit is a full pick.
The kit, and why it matters at this price
Most dots at this money sell you the optic and let you discover the mount is extra. The StrikeFire II ships with a cantilever ring mount set at a lower 1/3 co-witness for an AR-15, flip-cap covers, the CR2 battery and a T-15 Torx wrench. Owners consistently zero it fast: one reports it took roughly 15 rounds at 50 yards, and that the adjustments stayed put afterwards. The recurring complaint is the mount's single clamp screw. Torqued properly it holds, and owners say so, but more than one wishes for two.
“The build quality definitely surprised me, feels sturdy and well-made, not like some of the cheaper red dots. Zeroing was a breeze. Took maybe 15 rounds to get it dialed in perfectly at 50 yards, and the adjustments stay put.”

“The cantilever mount is the perfect height for co-witness with the iron sights on my AR. Controls are conveniently located and easy to manipulate even gloves. Only complaint is I wish it had a mount with 2 screws instead of one.”

The warranty is a real part of what you are buying
Vortex's VIP warranty is unlimited, unconditional and fully transferable: no card, no receipt, and it does not matter how the damage happened or where you bought it. It does not cover loss, theft or deliberate damage. At this price that promise carries weight, and owners lean on it. One with six Vortex optics says plainly that he has had failures, and that customer service was flawless every time. That is the honest shape of a value-brand purchase: not that nothing ever fails, but that a failure costs you a warranty claim rather than a new sight.
How far can you actually shoot it?
About 100 yards is where this sight is at home, and roughly 150 is where it stops being pleasant. Nothing in the optic gives out at that distance; the reticle does. A 4 MOA dot covers about four inches at 100 yards and about six at 150, so past that the dot is sitting on top of the thing you are trying to hit, and there is no magnification to help you see it. Owners describe exactly that: still centre-mass at 100 to 150 yards, dot blanketing four to five inches. For a defensive carbine, a PCC or a rimfire that is the whole use case. If you want groups rather than hits out there, you want a 2 MOA dot, a magnifier behind this one, or a prism scope.
An old design: what that costs you, and what it does not
You will read that the StrikeFire II is a decade-old design, said as though it settles the question. It does not settle it, but it is not nothing either, so here is the honest split. What the age does not cost you: Vortex still sells it as a current product, at an MSRP well above the retailer's street price, and still backs it with the unconditional VIP warranty, the enclosed tube and included cantilever mount are the same reasons people buy it today, and by Vortex's own figures the CR2 runs 50,000 hours with a 12-hour auto-shutoff behind it. What the age does cost you is a feature newer dots in this money have: motion wake. A SIG Romeo5 Gen 2, which sells for less than this, turns itself on when the rifle moves; this one waits for you to press a button, and switches itself off after 12 hours whether you meant it to or not. On a range rifle that is a non-issue. On a home-defence gun in a safe, it is the one thing to think about before you buy.
What owners flag, plainly
The most helpful negative review is a unit that arrived defective, with a dead green dot, and a slow exchange. With 613 reviews behind a 4.7 average that is not a pattern, but it is a real risk on any value optic and it is exactly what the VIP warranty exists for. The other honest limit is the reticle: a 4 MOA dot covers about four inches at 100 yards. One owner who runs six of them puts the trade squarely: better dots exist for hard use, with finer 1 MOA reticles and deeper pedigree, but they cost several times this.
Trade-offs, plainly
- A 4 MOA dot is coarse past 100 yards, covering four to five inches of the target. Precision work wants a 2 MOA dot.
- No motion wake. It has a 12-hour auto-shutoff instead, so a sight left on in a safe turns itself off rather than waking when you pick the rifle up.
- The included mount clamps with one screw, not two. It holds when torqued, but owners notice.
- It runs on a CR2, less common in a drawer than the CR1632 and CR2032 cells other dots use.
- At 12.8 oz with the mount it is heavy next to a slide-ride micro; this is a rifle optic, not a pistol one.
- No formal industry award, and it is not an Aimpoint. It is a value sight with a warranty, and it is honest about that.

Should you buy it, and what else to consider
- Buy it for an AR-15, PCC or rimfire that wants a rugged, warrantied, mount-included dot for range, home defence or plinking inside about 100 yards.
- Buy the red/green SF-RG-501 rather than the red-only model. Same sight, same price, one more option, and it is the variant actually in stock depth.
- Want motion wake for a home-defence rifle? The SIG Romeo5 Gen 2 wakes when the gun moves, at a smaller tube and a smaller price.
- Go micro for a pistol: this tube will not ride a slide. See the RMR-footprint Holosun HS407C-X2 (around $190 ) or our best pistol red dot picks.
- Want a bigger window for a shotgun or home-defence carbine? The Holosun HS510C (around $310 ) trades the tube for a 32x24mm view.
- Add magnification later with our best red dot magnifier picks, or read red dot vs holographic first.
FAQ
How much does a Vortex StrikeFire II cost?
Both base models cost the same at OpticsPlanet, checked on 14 August 2026; the model table above renders the current figure. That is the important change: the red-only SF-BR-504 and the red/green SF-RG-501 now sell for the same money, where the red/green used to cost about twenty dollars more. The retailer's list price is Vortex's own published MSRP rather than an inflated anchor. The three magnifier kits cost more again, each in step with the magnifier it bundles. Prices move, so confirm on the retailer page before you buy.
Is the Vortex StrikeFire II worth it?
For a range, home-defence or plinking rifle, yes, with one caveat: at its current price it sits above the promotional pricing this sight used to see, so it is a good buy rather than a steal. What you get is an enclosed nitrogen-purged 30mm tube, a 4 MOA dot with ten brightness settings, a 50,000 hour battery life and 12-hour auto-shutoff by Vortex's own figures, and a complete kit in the box: a cantilever mount that puts it at a lower 1/3 co-witness on an AR, flip caps, a CR2 battery and a Torx wrench. Behind it sits the unconditional Vortex VIP lifetime warranty. Owners rate it 4.7/5 across 613 verified reviews on OpticsPlanet, the deepest track record of any red dot we cover. If a 2 MOA dot or a smaller optic matters more to you than the mount being included, shop the alternatives below first.
What is the difference between the red and the red/green StrikeFire II?
One dot colour, and as of 14 August 2026 nothing else, including the price. OpticsPlanet lists the red-only model (SF-BR-504) and the red/green model (SF-RG-501) at the same price. Green can be easier to pick up against brown and green backgrounds for some eyes; red is the traditional choice. Since the red/green costs the same and simply gives you the option, it is the one we would buy, and it is also the one the retailer holds in depth, with the red-only model down to a handful of units when we checked.
What is the effective range of a Vortex StrikeFire II?
Out to about 100 yards it is doing exactly the job it was designed for, and it stays usable to roughly 150. The limit is the reticle, not the optic: at 1x there is no magnification to help you see the target, and a 4 MOA dot covers about four inches at 100 yards and six at 150, so the dot hides the part of the target you are trying to hit. Owners describe precisely that, still making centre-mass hits at 100 to 150 yards while the dot blankets four to five inches. For a defensive carbine, a PCC or a rimfire that is plenty. If you want to shoot small groups past 100 yards, a 2 MOA dot, a magnifier or a prism scope is the right tool.
Is the Vortex StrikeFire II discontinued?
No. Vortex still lists it as a current product, with a published MSRP well above the retailer's street price, and still backs it with the VIP warranty, checked on Vortex's own site on 14 August 2026. The design is an old one by red dot standards and you will see that said in forums as though it settled the question. It does not: the tube, the enclosed emitter and the included cantilever mount are the same reasons people buy it now, and the warranty is unconditional whether the design is new or not. What an older design does cost you is feature-set, and specifically motion wake, which newer dots in this money have and this one does not.
Does the Vortex StrikeFire II come with a mount?
Yes, and that is a real part of its value. The box includes a cantilever ring mount that sets a lower 1/3 co-witness on an AR-15, plus flip-cap lens covers, a CR2 battery and a T-15 Torx wrench. Most competing dots at this price make you buy a mount separately. One honest caveat owners raise: the mount clamps with a single screw rather than two. Torqued properly it stays put, but two screws would leave less to worry about.
Is a 4 MOA dot too big?
It depends how far you shoot. A 4 MOA dot covers about four inches at 100 yards, which is fast to pick up close in and perfectly adequate for defensive and range work inside roughly 100 yards, exactly what this sight is for. If you want to shoot precisely past that, a 2 MOA dot obscures less of the target. As one owner puts it, you can still hit centre mass at 100 to 150 yards, but the dot is covering four to five inches of the target out there.
Aimpoint PRO or Vortex StrikeFire II: which is better?
The Aimpoint PRO is the better sight and the StrikeFire II is the better buy for most people, which is the whole answer. The PRO is the duty benchmark: a 2 MOA dot, a battery Aimpoint rates in years rather than hours, and a service record that is the reason people quote it. It also costs multiples of this: Aimpoint holds it to a minimum advertised price, so OpticsPlanet shows the actual figure only once it is in your cart. Buy the PRO if the rifle is one you would bet on, or if the finer 2 MOA dot matters. Buy the StrikeFire II if the rifle is for the range, the truck or the house, where a tube dot at this money with a mount in the box and an unconditional warranty covers the job. What you give up is real and specific: a coarser dot, no motion wake, and a mount with one clamp screw instead of two.
