More from this brandAll Primary Arms rifle scopesOverview
A 1-6x24 second focal plane rifle scope from Primary Arms' SLx Gen4 line, built with an illuminated ACSS Nova Fiber Wire reticle. It ships mounted on a 30mm cantilever mount set at a 1.5 inch optical centerline with 0 MOA of cant.
Low-power variable scopes like this are built for AR rifles moving between close quarters and a couple hundred yards, with the 1x low end meant to work like a red dot. The reticle uses fiber-wire illumination rather than battery power alone, and an integrated throw lever changes magnification without breaking cheek weld.

Who it's for
AR-platform shooters who want one scope covering close range and mid-distance work, with the mount included. Not built for anyone needing first focal plane holdovers at every zoom setting.
Pros and cons
- 1-6x variable range covers close quarters through mid-distance
- Fiber-wire illuminated reticle, not purely battery dependent
- Integrated magnification throw lever
- Cantilever mount included with stated torque specs
- Second focal plane means reticle subtensions only hold true at max zoom
- Eye relief fixed at 4 inches, less forgiving for varied stances
- No rating or review data yet
Performance notes
At 1x the exit pupil is a wide 10.6mm, shrinking to 3.8mm at 6x, the normal tradeoff in this scope class, with eye relief listed at 4 inches across the range. The cantilever mount's 1.5 inch centerline is sized to clear common AR handguards, and torque specs are given for both the rings and the base for anyone mounting it themselves.
