Top 5 Scopes for Sako S20 – Quick Comparison List
Detailed Reviews of the Top 5 Scopes for Sako S20
1. Leupold Mark 5HD 3.6-18x44mm M5C3 FFP Riflescope
When I first mounted the Leupold Mark 5HD 3.6-18x44mm on my Sako S20 Precision (chambered in 6.5 Creedmoor), it felt like the rifle and optic were made for each other. Leupold’s legendary optical engineering complements the S20’s modular precision system perfectly, delivering crystal clarity and reliable tracking for long-range shooting.
Product Specs
Pros
Cons
Glass Clarity & Reticle
Leupold’s HD glass delivers one of the cleanest images I’ve seen in this price class. I observed minimal chromatic aberration, even when tracking steel silhouettes at 700 yards. The FFP TMR reticle is crisp, accurate, and ideal for fast holdovers.
Eye Relief & Eye Box
A forgiving eye box with 3.6 inches of consistent eye relief. Even at 18x, the image was easy to center quickly—perfect for dynamic stages or hunting scenarios.
Durability
The Mark 5HD is built like a tank but feels agile. Its 35mm tube construction provides superior strength while remaining lightweight. It’s waterproof, fogproof, and recoil-tested beyond .338 Lapua standards.
Elevation & Windage Knobs
The M5C3 turrets feature Leupold’s patented ZeroLock system, giving me 30 MILs of total adjustment with impeccable return-to-zero performance. The tactile feel is distinct—no mush, no play.
Magnification & Parallax
Smooth magnification ring with a parallax adjustable from 50 yards to infinity. I performed a box test—tracking was spot-on within 0.1 MIL deviation across 12 MILs of travel.
Mounting & Accessories
I used Leupold 35mm Mark 4 rings on a 20 MOA rail. Installation was straightforward; zeroing took only 6 rounds at 100 yards.
My Experience
I’ve fired over 400 rounds with this setup, including several cold-bore tests. The zero never shifted once. In low-light hunts, it outperformed every other optic I tested on the S20.
Online Discussion
On Reddit’s r/longrange, many Sako S20 owners echo my findings—calling the Mark 5HD “the most natural optic pairing” for the rifle.
Verdict
If you want a professional-grade optic that matches the S20’s precision DNA, the Mark 5HD is it.
2. Vortex Optics Razor HD LHT 4.5-22x50 FFP
The Vortex Razor HD LHT 4.5-22x50 strikes the ideal balance between lightweight portability and precision. I mounted it on my Sako S20 Hunter, chambered in .308 Win, and found it excelled for both stalking and mid-range steel.
Product Specs
Pros
Cons
Glass Clarity & Reticle
Vortex’s HD optical system offers color fidelity on par with optics twice its price. The HSR-5i illuminated reticle gives clear, thin stadia lines perfect for precise holdovers.
Eye Relief & Eye Box
Eye relief measured about 3.8 inches, making it comfortable for heavy recoils. The wide eye box allows fast target acquisition, even at 20x magnification.
Durability
Built on a 30mm single-piece aluminum tube, the Razor HD LHT is O-ring sealed and Argon purged. I tested it through fog, rain, and 10°F cold—the image stayed pristine.
Elevation & Windage Knobs
The elevation turret has a locking mechanism and a well-defined Zero Stop. Clicks feel crisp, and tracking through a tall-target test was accurate to within 0.05 MIL deviation.
Mounting & Accessories
Mounted with Vortex Precision Match rings (30mm, medium height). Took 5 shots to zero. The included sunshade and lens covers are quality additions.
My Experience
From 100 to 800 yards, my hits were consistent. The parallax adjustment is silky smooth, and the reticle illumination helped in shaded woodland hunts at dawn.
Online Comments
Vortex users praise this model as “the do-it-all optic for hunters with precision standards.”
Verdict
Ideal for Sako S20 users who hunt yet demand long-range precision.
3. Swarovski Z5 3.5-18x44 P
If you value clarity above all else, the Swarovski Z5 3.5-18x44 P delivers optical performance that feels almost surreal. Paired with my Sako S20 Hunter, it became my go-to for mountain hunts where every gram and every ray of light matters.
Product Specs
Pros
Cons
Glass Clarity & Reticle
Swarovski’s Z5 glass remains the benchmark for hunting optics. I could spot mule deer at over 600 yards under dusk light with no noticeable chromatic aberration. The BRX reticle is clean and minimal—ideal for hunters, though less tactical.
Eye Relief & Eye Box
Comfortable 3.74-inch eye relief and an incredibly forgiving eye box. Target acquisition feels instantaneous.
Durability
Despite its delicate look, it’s surprisingly rugged. I’ve used it through rain, dust, and 5°F cold without fogging or POI shift.
Turrets
The ballistic turret system allows three customizable zero points—perfect for hunting different distances. Tracking was flawless across 15 MOA of adjustment.
Mounting & Zeroing
I used lightweight aluminum 1” rings. Achieved a 100-yard zero in 3 shots using 143-gr ELD-X ammo. Held zero for an entire season.
My Experience
The Sako S20 and Z5 combination feels perfectly balanced in the hand. The rifle stays maneuverable while maintaining sub-MOA accuracy out to 700 yards.
Online Comments
Hunters on forums often describe it as “Sako’s natural hunting partner.”
Verdict
If your S20 is used mainly for hunting, this is the pinnacle of optical refinement and portability.
4. Arken Optics EP5 5-25x56 FFP
The Arken EP5 5-25x56 is the best value long-range scope you can pair with the Sako S20. It delivers FFP functionality, great glass, and robust mechanics at a price far below its premium rivals.
Product Specs
Pros
Cons
Glass Clarity & Reticle
The Japanese ED glass punches well above its weight class. The VPR MIL reticle offers detailed holdover marks for precision shooting.
Eye Relief & Eye Box
Consistent 3.4–3.6 inches of eye relief. The eye box tightens slightly above 20x but remains serviceable.
Durability
Machined aluminum housing feels overbuilt. I ran 200 rounds of .308 Win and 6.5 Creedmoor—zero held tight. The turrets lock positively, even in cold-weather use.
Elevation & Windage Knobs
Positive clicks with tactile feedback. 32 MIL elevation adjustment makes it suitable for ELR shooting. Zero Stop is reliable and easy to set.
Mounting
Used Arken 34mm rings on a 20 MOA rail. Needed 7 rounds to get perfect zero.
My Experience
I performed a tall target test at 100 yards—tracking error was just 0.07 MIL over 12 MILs. The reticle illumination is subtle but sufficient for dawn use.
Online Comments
Shooters on r/longrange call it “the budget scope that performs like a $1,500 optic.”
Verdict
Perfect for Sako S20 owners seeking high performance without breaking the bank.

Turrets
Audible and tactile clicks with accurate tracking. The precision zero stop is intuitive and dependable.
Mounting & Experience
Mounted using 30mm Warne rings. Zeroing took just 5 rounds. Over 250 rounds later, zero stayed consistent.
