The Primary Arms SLx 1-6x24 Gen IV LPVO Rifle Scope with the ACSS Aurora 5.56 Meter reticle (part number 610182, SKU PA-SLX-1-6X24S-AUR-5M6) is a 1-6x magnification, 24 mm objective low-power variable optic on a 30 mm tube, with a second focal plane (SFP) ACSS Aurora 5.56 Meter reticle and red night-vision-compatible illumination. It adjusts in 0.1 MIL clicks, offers 120 MOA of windage and elevation travel, and runs from a single CR2032 cell.
The Aurora is the reticle to choose if you shoot 5.56 and think in metres. Its bullet drop compensation, ranging stadia, moving-target leads and wind holds are all laid out for the 5.56 trajectory and marked in metres rather than yards — which is how British ranges, British stalking and British competition all measure distance, so there is no conversion in your head between seeing the target and taking the shot.
How It Compares
This is the calibre-specific option in the SLx 1-6x24 family. The ACSS Nova versions use MIL subtensions instead and suit any cartridge: red Nova in black, green Nova in black, red Nova in Flat Dark Earth and green Nova in Flat Dark Earth. For more magnification, the SLx 1-10x28 rifle scope reaches 10x. A 30 mm mount is required, such as the Primary Arms SLx 30 mm cantilever mount.

Frequently Asked Questions
Which calibre is the ACSS Aurora 5.56 Meter reticle calibrated for?
The ACSS Aurora 5.56 Meter reticle is calibrated for 5.56, and its ranging and holdover marks are laid out in metres rather than yards.
What does the ACSS Aurora reticle actually do?
The ACSS Aurora combines four aiming aids in one reticle: bullet drop compensation so you hold over rather than dial for distance, ranging stadia that estimate the distance to a target of known size, moving-target leads for a target crossing your front, and wind holds either side of centre.
Why does a metre-based reticle matter in the UK?
British ranges, deer stalking and practical competition all state distances in metres, so a reticle marked in metres removes the mental conversion from yards and lets you match the range you were given straight to a holdover mark.
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 Aurora stays large and quick to use at 1x, while its ranging and holdover marks 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 illumination usable with night vision?
Yes. The red illumination on this SLx 1-6x24 Gen IV includes night-vision-compatible settings, so the reticle can be used behind a night-vision device without washing out the image.
