Primary Arms SLx 1-6x24mm SFP Gen IV ACSS Nova Riflescope

The SLx 1-6x24 is the best selling carbine scope Primary Arms makes, and the Gen IV rework touched the parts that matter. The optical system was upgraded for clarity, the throw lever is now an integrated dovetail instead of a clamp on ring, and the reticle lineup moved to the newest ACSS designs. At 1x it runs like a red dot with both eyes open. At 6x it stretches a carbine well past what iron sights can do.

The ACSS Nova reticle sits in the second focal plane, so its holds keep the same visual size through the magnification range and you learn one sight picture instead of six. Primary Arms builds the ACSS family around a center aiming point with surrounding holds for drop and wind, which is why the line caught on with people who shoot at distance without dialing. Mount it in a cantilever at AR height, zero it, and use the bottom of the range as a close quarters sight.
