Overview
The Primary Arms SLx 3X Micro Magnifier is the current value pick in Primary Arms' magnifier line. It keeps the optic body down to 5.3 oz and 2.83 inches long, which makes it easier to fit behind compact red dots and 1x prism sights than older full-size magnifiers.
The current SLx Micro uses a 21 mm objective, 7.0 mm exit pupil, 2.40 inches of eye relief, and a 35.2 ft field of view at 100 yards. It uses Primary Arms' 2-bolt magnifier mount pattern, so budget buyers can run a basic flip-to-side mount while users chasing higher centerlines can step into compatible aftermarket mounts.
Pick it when weight, price, and compact packaging matter more than maximum eye relief. If you need more range from the same red-dot setup, step up to the Primary Arms GLx 6X instead.
