Furthermore, this also means any special adaptors like those for the AK, also function with the optic. This means any QD mounts designed for the ACOG will function with the PA scope. For instance, underneath the scope, the 5x ACSS Prism uses the same mounting screws as an ACOG. What’s even more interesting, is that the dots on either side of the range subtensions offer the same function on targets out to 800 meters! ACOG CompatabilityĬlearly, the Primary Arms Prismatic optics take inspiration from the ACOG, but what some shooters don’t know is that they can use many ACOG components. This makes rapid acquisition and engagement of moving targets much easier. In fact, the outer edges of the horseshoe are meant as approximate windage holdovers to running targets. For instance, the illuminated horseshoe at the top functions as a two-eye red dot crosshair for rapid, close-quarters shooting while simultaneously providing quick, useful holdovers. At first glance, it seems like your basic BDC crosshair with subtensions marking the proper holdovers out to 800 meters – but it’s much more than that. What makes the ACSS so great, is its combination of visual simplicity and incredible versatility. ACSS ReticleĮven if tomorrow, Primary Arms changed their scope bodies to laminated cardboard and their lenses to saran wrap, their ingenious ACSS reticle would still make their optics worth a look.

Deceptively simple, the ACSS 556 reticle is brilliant! It provides a BDC for known distances and even has holdovers for moving targets built-in.

Indeed, the SLX is practically dripping with features and quality despite its relatively low price tag.

That said, the virtues Primary Arms SL X 5X are not simply limited to those of any old prism optic. There are a number of reasons, but the two big ones are increased durability and better weapon balance.
