Overview
The Primary Arms Compact PLxC 1.5-12x36mm FFP is a first-focal-plane rifle scope built around the ACSS Raptor 5.56/.308 illuminated reticle, a caliber-matched BDC system for those two cartridges.
At 9.75 inches and 19.7 ounces it is built for shooters who want to move between close-range acquisition and 12x precision work without swapping optics. Because the reticle is caliber-matched to 5.56 and .308, its ranging stadia and holdovers will not track correctly if mounted on a rifle chambered in anything else.
- ACSS Raptor 5.56/.308 first focal plane illuminated reticle
- 1.5-12x36mm magnification, Japanese ED glass
- AutoLive motion-sensing illumination
- 100 MOA elevation, 50 MOA windage travel
Who it's for
AR-platform and .308 rifle owners who want one scope for both close and mid-range engagement without external ballistic data. Not the right choice for other calibers, since the ACSS Raptor's holdovers are specific to 5.56 and .308.
Strengths and trade-offs
Drawn from this product's published specifications.
- FFP reticle keeps ranging marks accurate at any magnification
- Caliber-matched ACSS Raptor holdovers for 5.56 and .308
- AutoLive shuts illumination off automatically when stationary
- Compact 9.75-inch, 19.7-ounce package with a 1.5-12x range
- Reticle only matches 5.56 and .308 ballistics
- No rating or review data yet to confirm field durability
Performance notes
The ACSS Raptor reticle is first focal plane, so its subtensions for ranging, wind holds, and moving target leads stay accurate at any magnification from 1.5x to 12x, not just at one calibration point. Japanese ED glass and a 36mm objective are meant to hold brightness and reduce color fringing at the top of that range. AutoLive senses when the rifle stops moving and powers the illumination down, then reactivates it on motion, and the elevation turret gives 100 MOA of adjustment against 50 MOA of windage. Parallax is adjustable from 10 yards to infinity, useful given the low end of the magnification range.
