The Primary Arms SLx 1-6x24 Gen IV LPVO Rifle Scope with green ACSS Nova illumination (part number 610213, SKU PA-SLX-1-6X24S-NOVA-G) is a 1-6x magnification, 24 mm objective low-power variable optic on a 30 mm tube, with a second focal plane (SFP) ACSS Nova fiber-wire reticle illuminated in green. 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, in a black finish.
Green is the reason to choose this variant. The human eye is most sensitive to wavelengths in the green part of the spectrum, so against foliage, dark hedgerows and low winter light a green centre often registers faster and at a lower brightness setting than the equivalent red — which also means less battery drain and less bloom for shooters who find red illumination flares.
How It Compares
This is the green-illuminated black version. The SLx 1-6x24 Gen IV rifle scope with red ACSS Nova illumination is the same optic with a red centre, and both illumination colours are also offered in Flat Dark Earth: green in FDE and red in FDE. For a calibre-specific 5.56 holdover reticle rather than the MIL-based Nova, see the SLx 1-6x24 with the ACSS Aurora 5.56 Meter reticle, and for a wider zoom range 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 and all LPVO rifle scopes, and read our comparison of green and red illumination.

- Deer stalking and woodland shooting, where a green centre stands out against foliage
- Civilian Service Rifle and practical rifle in typical British overcast and low light
- Night fox and vermin control at dusk, where lower illumination settings suffice
- Shooters who find red illumination blooms or flares for them

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.
Why choose green illumination over red?
The human eye is most sensitive to green light, so a green reticle centre is often easier to pick up against foliage and in poor light, and it can be seen clearly at a lower brightness setting, which saves battery and reduces bloom.
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 the green illumination usable in bright daylight?
Yes. The green illumination on this SLx 1-6x24 Gen IV is daylight-bright at its highest of 11 settings, so the reticle can be used like a red dot sight at 1x in full sun.
