Introduction to Red Dot Sights
Introduction to Red Dot Sights
Red dot sights have become one of the most popular types of optics for shooters of all levels, from beginners to professionals. Unlike traditional scopes, red dot sights use a simple illuminated dot as the aiming point, allowing for quick target acquisition and fast shooting with both eyes open. They are especially favoured for close to medium-range shooting, where speed and accuracy matter most.
Designed to be lightweight and easy to use, red dot sights don’t magnify the target but instead provide a clear, bright aiming point that stays aligned with your firearm’s barrel. This makes them ideal for a wide range of shooting activities, including hunting, tactical shooting, competition and airsoft.
In this blog, you’ll learn why red dot sights are so effective, how they work, and what advantages they offer compared to other sighting systems.
Why are they effective?
Red dot sights are highly effective for fast and accurate shooting because they allow shooters to quickly acquire their target without the need to perfectly align traditional iron sights. One of the biggest advantages is their parallax-free design, meaning the red dot stays on target even if your eye position shifts slightly behind the sight. This feature ensures that as long as the dot is on the target, your shot will be accurate, which is especially valuable in dynamic shooting situations where quick reaction and movement are involved.
Another key benefit of red dot sights is their wide field of view, which lets you keep both eyes open while aiming. This broad perspective helps maintain better situational awareness, making it easier to track moving targets and stay aware of your surroundings. Combined with the bright, crisp aiming dot, this wide field of view improves target acquisition speed and accuracy, making red dot sights an excellent choice for close-to medium-range shooting scenarios like hunting, tactical engagements, and competitive shooting.
How do they work?
Red dot sights work by projecting a small, illuminated red dot onto a specially coated lens inside the sight. This dot is generated by an LED light source and appears to float over the target when you look through the sight. Because the lens is angled to reflect only the LED’s light back to your eye, the dot stays bright and clear without magnifying the target itself. This setup allows for quick aiming and target acquisition with minimal eye strain. Holographic sights operate on a similar principle but use a laser-generated hologram of the reticle embedded inside the sight’s window. Instead of a simple LED dot, holographic sights project a more complex reticle pattern, which can offer more precision and customisation. Both types of sights are designed to be parallax-free, meaning the reticle remains aligned with the target regardless of your eye position.
A red dot sight uses an LED to project a simple illuminated dot onto a lens for fast aiming, while a holographic sight uses a laser to project a more complex reticle image as a hologram onto the viewing window. Red dots are typically lighter and more energy-efficient, while holographic sights offer finer reticle detail and better performance under magnification or in adverse conditions.
What are the advantages and disadvantages for red dot sights?
Advantages of Red Dot Sights- Fast target acquisition: Ideal for close to mid-range shooting; great for quick reactions.- Both-eyes-open shooting: Improves situational awareness and depth perception.- Parallax-free (in practical terms): The dot remains on target even if your head isn't perfectly aligned.- Lightweight and compact: Won’t add much bulk to your firearm.- Simple to use: No magnification or complicated adjustments; intuitive for beginners.- Long battery life: LED technology allows some models to last thousands of hours.
Disadvantages of Red Dot Sights- No magnification: Not ideal for long-range shooting without a magnifier.- Can wash out in bright light: Some red dots may be hard to see in direct sunlight if the brightness is too low.- Battery dependence: If the battery dies and there's no backup sight, you're out of luck.- Limited reticle options: Basic dots may lack the precision or holdover features of more advanced optics.- Less precise than scopes at distance: Dot size (MOA) can cover smaller targets at longer ranges.
Red dot sights are a popular choice for shooters who value speed, simplicity, and versatility. Their parallax-free design and ability to shoot with both eyes open make them ideal for quick target acquisition and close to mid-range engagements. While they lack magnification and rely on batteries, their lightweight build, long battery life, and user-friendly operation make them a reliable option for everything from airsoft to competitive shooting. Understanding their strengths and limitations helps ensure you choose the right optic for your specific needs.

Choosing the Correct Picatinny Rail for Sako 75 / 85 / L461 (Vixen)
Choosing the Correct Picatinny Rail for Sako 75 / 85 / L461 (Vixen)
If you’re fitting a Picatinny rail to a Sako rifle - specifically a Sako 75, Sako 85, or the classic L461 “Vixen” - the single most important step is identifying the action length. Pick the wrong action size (extra‑short, short, medium, long or magnum) and the rail may not line up with the dovetail or screw holes, block bolt travel, or force awkward ring heights and a ruined cheek weld.
This short guide explains why action size matters, how Sako groups its actions, and three practical, reliable ways to determine whether your rifle is XS / S / M / L / XL (inspection of markings, cartridge mapping, and simple measurements). Use it before you buy a rail - it will save time, money, and the risk of an ill‑fitting mount.
Why action size matters for Picatinny rails
Picatinny rails and adapter bases are cut and drilled to match an action’s physical dimensions: dovetail span, receiver top length, and screw/hole spacing. A rail for the wrong action length can:
• Fail to line up with mounting holes or dovetails • Overhang the receiver or leave gaps under the rail • Interfere with bolt travel or bolt handle clearance • Force scope rings to sit at incorrect heights and ruin your cheek weld
So the first step before thinking about rail height, ring choice, or scope position is to correctly identify the action length (extra‑short / short / medium / long / magnum).
Sako action families - quick overview
Sako used multiple action lengths across the 75 and 85 lines and the L461 Vixen. Names differ between lines but map to the same practical groups:
• Sako 75: commonly referenced as I, II, III, IV, V, VI, SM (short magnum).
• Sako 85: commonly referenced as XS, S, SM, M, L, XL.
• Vixen (L461): historically equivalent to extra‑short / XS / I.
Broad cartridge-to-action mapping (examples):
• XS / I / Vixen (extra‑short): .222, .223, .22‑250
• S / II (short): .243, .308, 7mm‑08
• SM / III (short magnum/medium): WSM family, short‑mag cartridges
• M / IV (medium): .270 Win, .30‑06
• L / V (long magnum): 7mm Rem Mag, .300 Win Mag
• XL / VI (extra‑long): .338 Lapua and very large magnums
These groupings are the common, practical way vendors label rails and adapters.
Three reliable ways to determine your action length
Safety first: always unload the rifle, remove the bolt if you’ll be working inside the receiver, and handle the firearm in a safe, clear area.
1) Check the markings or paperwork
Look for model/action stamps on the barrel or receiver, and check original paperwork. If it says Sako 75 II, Sako 85 S, or L461 Vixen, treat that as authoritative - those designations map directly to an action family.
2) Identify by chambering (cartridge)
Cross‑reference the chambering stamped on the barrel with the cartridge‑to‑action mapping above. This is quick and usually accurate unless the rifle was rechambered or heavily customised.
Caveat: rechambered/custom rifles may not follow the standard mapping - when in doubt, measure.
3) Measure the receiver/dovetail span (when markings or chambering aren’t conclusive)
Unload, remove the bolt, and place the rifle on a stable surface.
Use callipers or a ruler to measure the length of the exposed receiver top or the dovetail/ejection‑port span.
Compare to these approximate bands (millimetres first, then inches):
• Extra‑short / XS / I (Vixen): ~55–60 mm (2.17–2.36 in)
• Short / S / II: ~65–70 mm (2.56–2.76 in)
• Medium / M / III–IV: ~75–80 mm (2.95–3.15 in)
• Long / L / V: ~85–90 mm (3.35–3.54 in)
• Extra‑long / XL / VI: >95 mm (>3.74 in)
These ranges are approximate, but are typically enough to distinguish short vs medium vs long actions reliably.
How to use the action size when choosing a Picatinny rail
Buy rails that explicitly list the action, e.g. “Fits Sako 85 S” or “Fits Sako 75 III/IV.” Vendors frequently group rails by action length.
If a rail is sold generically as ‘Sako’ with no action size, ask the vendor which action(s) it is cut for - dovetail span and screw spacing differ by length.
Many dovetail‑to‑Picatinny adapters list fitment ranges (for example, “fits Sako 75 I–III” or “fits Sako 85 S/M”). Match that range to your action size.
Tip: prefer vendors who show bolt‑clearance photos or provide explicit bolt‑operation confirmation for the listed action size.
Special case - Sako Vixen (L461)
The L461 Vixen uses the extra‑short form factor. Modern XS / I rails often fit L461 rifles, but some early Vixen receivers have slight differences. For vintage Vixen rifles, choose rails that explicitly list L461 / Vixen compatibility or consult a gunsmith.
Practical buyer workflow (step‑by‑step)
• Check for a stamped/model designation on the barrel or receiver.
• If unknown, read the chambering and map it to an action family.
• If still unsure, measure the ejection‑port/dovetail span and compare to the ranges above.
• Order a rail that explicitly lists your action size/model (don’t buy a generic “Sako” rail without confirmation).
• Before purchase, ask the seller: “Will this rail interfere with bolt operation on a Sako [your action size]? Can you provide a photo showing bolt clearance?”
• If receiver drilling/tapping is required and you’re uncertain, consult a qualified gunsmith.
Examples
Example 1: Rifle stamped Sako 85 .308 Win → .308 maps to S (short) action → buy a rail listed for Sako 85 S / short action.
Example 2: Old Vixen L461 .222 Rem → maps to XS / I → get a rail listed for L461 / Sako extra‑short.
Example 3: No markings, chambering unknown - measured dovetail span 78 mm → falls in the M / medium band → buy rails labelled for M / medium action.
Quick troubleshooting & caveats
Interchangeability myth: Don’t assume a Sako 75 rail will always fit a Sako 85, even if both are labelled “Sako.” Action length and hole spacing matter.
Variant differences: special editions, target versions, or pre‑production runs may have slightly different receiver machining - verify with photos and seller claims.
When in doubt, measure and ask: a few millimetres can make or break fit; vendors and gunsmiths prefer concrete numbers.
Conclusion
Correctly identifying your Sako rifle’s action length is the foundation for a safe, functional, and comfortable Picatinny rail installation. Confirm whether your rifle is extra‑short, short, medium, long, or extra‑long using stamped markings, chambering, or simple measurements. Then choose a rail explicitly matched to that action to ensure secure attachment, bolt clearance, and correct scope positioning. Taking these steps prevents costly mistakes and ensures your optics and rifle work together reliably. READ ARTICLE

- No locking turrets: they’re solid, but they don’t lock, which some people prefer.
- Bulky overall: can be a pain to mount, especially on lower-profile rails.
Falcon S40i+ 4-40x58i FFP ED IR 0.1MRAD 34mm Competition Rifle Scope
This is a purpose-built, high‑magnification competition scope: huge zoom range, big objective, FFP reticle and fine 0.1 mrad clicks. Great for precision work where minute adjustments and long-range resolution matter.
Pros
- Massive zoom range (4–40×): super flexible for close-to‑long shots; one optic covers a lot of ground.
- 58 mm objective: excellent light gathering for late‑day/early‑morning strings.
- FFP + 0.1 mrad clicks: reticle subtensions work at any mag and clicks give very fine, repeatable adjustments.
- ED glass: better color, contrast and resolution versus basic glass (helps at long range).
- 34 mm tube: lots of internal adjustment travel (30 MRAD) for dialling big elevation corrections without add-ons.
- Competition features: designed for fast, precise dialling: tactile/audible turrets, zero‑stop and easy-to-read markings.
- Illumination (IR): usable in low light or against dark targets; handy for certain reticle choices.
- Price: Only £479 and comes with sunshade, magnetic flip covers and bikini covers.
Cons
- Heavy and bulky: big objective + rugged turrets = weight. Not ideal if you hike a lot.
- Large objective needs clearance: may force higher mounts and can snag on gear.
- Edge softening at extreme zooms: most scopes get a bit soft at full mag; expect this to happen near 40× on some samples.
- Complexity: learning curve for new users: dialing, holdovers, and reticle reading at variable mags takes practice.
- Mounting and balance: requires a solid mount and good rifle balance; cheap rings won’t cut it.
Vortex Strike Eagle 5-25x56 FFP Illuminated EBR-7C MRAD SF Rifle Scope
If you want a heavy‑hitting long‑range scope that gives you a lot of features for the price, this one’s hard to beat. Big magnification range, first‑focal‑plane reticle, zero‑stop, locking turrets, and good glass. But it’s not perfect - expect trade‑offs, especially when pushing it hard at 25× or in really bright conditions.
Pros
- Magnification: Big zoom range (5–25×) covers mid to long range really well
- Objective: Big 56mm objective lens = better low-light performance
- Reticle: FFP reticle (EBR-7C) works at all magnifications - great for holdovers

- Illumination strength: Illumination is kind of weak in bright daylight – it works well in low light, but you won’t notice it much under the sun.
- Eye box: Eye box is tight at high mag – once you zoom past ~20×, you really need to get your head just right or the image blacks out.
- Rings: You’ll probably need high rings – between the huge objective and the long body, plan your mount setup carefully.
- Price: Most expensive on our list at £879

Cons
- It's a unit: big, heavy, and long. You’ll feel it if you're running around with your rifle.
- Not a ton of elevation: 26 MIL is decent, but if you're pushing extreme range, you might want more adjustment.
- Illumination is so-so: works fine in low light, but in bright daylight, it kind of disappears.
- Zoom ring edges are a bit sharp: not a big deal, but not the most glove-friendly design.
- Price: More expensive most of our list at £863.95.
WULF Defender 2.0 ED 5-25x56 FFP W-MIL5 0.1 MRAD Rifle Scope
Dude, this scope is a beast. For the price, it gives you a lot: strong zoom range, good glass, useful features like zero stop and turret lock, and a reticle you can actually work with across the magnification range. When you’re dialling in on steel at 800+ yards, it gives you what you need.
Pros
- Solid glass: colours are decent and the image stays clean.
- Magnification: That zoom range (5 to 25×) is sweet - good flexibility for all sorts of distances.

- Illumination: works when it needs to - good in lower light or darker targets.
- Price: For what you get, you’re getting strong bang-for-your-buck at £449.99.
Cons
- It’s heavy: Like, you’ll feel it over a long day of carrying or on a lighter setup.
- In full daylight, the illumination kinda fades: you won’t rely on it for brightness wars.
- It’s long: means you’ll have to think about ring height and how your rifle geometry lines up.
- If you don’t use that big elevation travel, some of its features might feel like dead weight.

First Focal Plane vs. Second Focal Plane Scopes | Optics Guide
First Focal Plane vs. Second Focal Plane Scopes | Optics Guide
When choosing a rifle scope, one of the most important decisions you’ll face is whether to go with a First Focal Plane (FFP) or a Second Focal Plane (SFP) design. This choice affects how the reticle behaves as you change magnification - and it can have a big impact on how you use your scope, especially for long-range shooting or tactical applications.
The main difference lies in the position of the reticle within the scope’s optical system. In a First Focal Plane scope, the reticle grows and shrinks as you zoom, keeping its proportions relative to the target. This lets holdovers, range estimates, and ballistic calculations stay accurate at any magnification.
In contrast, a Second Focal Plane scope has the reticle behind the magnification lens. The reticle stays the same size no matter the zoom, which many shooters find easier at lower magnification. However, range/holdover markings are only accurate at one specific magnification—usually the highest.
Understanding the difference between FFP and SFP scopes will help you choose the right optic for your needs, whether you're hunting, target shooting, or engaging in precision long-range work.
First Focal Plane (FFP) Scopes
Pros:
• Accurate holdovers and ranging at all magnifications (reticle subtensions stay true at any zoom level)
• Ideal for long-range and tactical shooting
• Great for dynamic environments (zoom without losing reticle scale accuracy)
• Versatile for shooters who use reticle markings for adjustments
Cons:
• Reticle can be hard to see at low magnification (very small/thin when zoomed out)
• Can be more expensive (more complex to manufacture)
• More cluttered at high magnification (reticle may appear thick or busy)
Second Focal Plane (SFP) Scopes
Pros:
• Reticle size stays the same at all magnifications (easy to see at low zoom)
• Often simpler and less expensive
• Ideal for hunting or casual shooting (set distances with minimal holdovers)
• Cleaner sight picture at all magnification levels (simpler reticles)
Cons:
• Reticle subtensions are only accurate at one magnification (usually the highest power)
• Holdovers and ranging can be unreliable unless you're at that exact zoom level
• Less suited for advanced or competitive long-range shooting
Which One Should You Choose?
• Choose FFP if you're doing precision shooting, long-range, or tactical work, and use your reticle for holdovers or ranging.
• Choose SFP if you prefer a simple, consistent sight picture, and mainly shoot known distances where adjustment isn’t required.
Choosing between FFP and SFP scopes depends on how you plan to use your rifle optic. FFP reticles scale with magnification, keeping holdovers/ranging accurate at any zoom—great for long-range/tactical shooting. SFP reticles stay a constant size for a simpler, clearer view, though their markings are precise at only one zoom. Understanding these differences helps you match the right scope to your needs.
