More from this brandAll Primary Arms rifle scopesOverview
A second focal plane rifle scope from Primary Arms with an illuminated ACSS Nova Fiber Wire reticle, built for close-range to long-distance target engagement in a compact 34mm tube.
The SLX 1-10x28mm targets shooters who want one scope to cover both close-quarters and reach-out shots, using a fiber-optic-lit reticle and a low-profile throw lever for fast magnification changes. It carries Primary Arms' transferable lifetime warranty, though owner feedback on this listing flags softness at the top of the zoom range.
- ACSS Nova Fiber Wire illuminated reticle
- 1/2 MOA clicks, 40 MOA total travel
- 10.5 inch, 19.1oz, 34mm aluminum tube
- Integrated throw lever for fast zoom changes
Who it's for
Fits shooters who move between near and far targets and want MIL subtensions with integrated ranging built into the reticle. Less suited to those who mainly shoot at 7-10x magnification and need consistently sharp glass at that end.
Pros and cons
- Fiber-optic illuminated reticle needs no battery to glow
- Fast 1x to 10x range with integrated throw lever
- Compact 34mm tube at 19.1oz
- Transferable lifetime warranty
- Image reportedly softens from 7x to 10x for at least one owner
- A replacement unit didn't resolve the blurriness for that reviewer
Performance notes
The ACSS Nova Fiber Wire reticle uses fiber-optic illumination for a bright aiming point without draining a battery, with 1/2 MOA clicks across 40 MOA of total windage and elevation travel. At 1x it delivers a 110 foot field of view at 100 yards, and the integrated throw lever lets shooters switch from 1x to 10x quickly. One reviewer rated it close to Primary Arms' higher-end PLx-C in performance, while another found the picture blurry from 7x to 10x and said a replacement unit had the same issue.
