The Primary Arms SLx 1-6x24 Gen IV LPVO Rifle Scope in Flat Dark Earth (part number 610207, SKU PA-SLX-1-6X24S-NOVA-FDE) is a 1-6x magnification, 24 mm objective low-power variable optic on a 30 mm tube, finished in Flat Dark Earth, with a second focal plane (SFP) ACSS Nova fiber-wire reticle and red daylight-bright illumination. It adjusts in 0.1 MIL clicks, offers 120 MOA of windage and elevation travel, and runs from a single CR2032 cell across 11 brightness settings.
Optically and mechanically this is the same scope as the black version; the difference is the finish. Flat Dark Earth matches tan and coyote furniture, and on a rifle built around FDE handguards and stocks it looks deliberate rather than assembled from spare parts. It also disappears rather better against dry grass and stubble than black does.
How It Compares
This is the Flat Dark Earth scope with red illumination. The SLx 1-6x24 Gen IV in Flat Dark Earth with green ACSS Nova illumination is the same finish with a green centre, and both illumination colours are also available in black: red in black and green in black. For a 5.56-specific holdover reticle instead of the MIL-based Nova, see the SLx 1-6x24 with the ACSS Aurora 5.56 Meter reticle; for more magnification, the SLx 1-10x28 rifle scope. A 30 mm mount is required, such as the Primary Arms SLx 30 mm cantilever mount. Browse the Primary Arms LPVO range, all LPVO rifle scopes and optics for straight-pull rifles.
Ideal For
- Civilian Service Rifle and practical rifle builds finished in tan or coyote
- Straight-pull AR-platform rifles used for practical and service disciplines in Great Britain
- Practical shotgun and 3-Gun stages mixing close targets with distant plates
- Deer stalking and vermin control over dry grass and stubble, where FDE is less conspicuous than black

Frequently Asked Questions
What does the ACSS Nova reticle actually do?
The ACSS Nova is a fiber-wire reticle with a daylight-bright illuminated centre surrounded by MIL-based subtensions, which let you range a target of known size, hold over for bullet drop instead of dialling the turret, and hold off for wind and for moving-target leads without taking your eye from the sight.
Which calibre is the ACSS Nova reticle calibrated for?
The ACSS Nova is a milliradian-based reticle rather than a calibre-specific bullet drop compensator, so its subtensions are stated in MIL and work with any cartridge once you know your own drops in MIL.
Is the Flat Dark Earth version optically different from the black one?
No. The Flat Dark Earth Primary Arms SLx 1-6x24 Gen IV is the same optic with the same specification as the black version, and only the exterior finish differs.
What does second focal plane mean on a 1-6x scope?
Second focal plane means the reticle stays the same visual size as magnification changes, so the ACSS Nova remains large and easy to see at 1x, while its MIL subtensions are only correct at one stated magnification, which on this scope is the top of the range.
What mount does this scope need?
The Primary Arms SLx 1-6x24 Gen IV has a 30 mm tube, so it requires 30 mm rings or a 30 mm cantilever mount, which is not included.
Is it a true 1x at the bottom of the magnification range?
Yes. The Primary Arms SLx 1-6x24 Gen IV is a true 1x at its lowest setting, so the image through the scope matches the unaided eye and both-eyes-open shooting is practical.
