Primary Arms SLx 1X MicroPrismT with RDB Illuminated T-Dot Reticle - H1/T1 Footprint

For shooters who demand the fastest possible target acquisition, the Primary Arms SLx 1X MicroPrism with RDB Illuminated T-Dot reticle delivers a brilliantly lit, simple aiming point with the clarity and durability advantage of a prismatic optic over a standard red dot.

The Primary Arms SLx 1X MicroPrism is a 1x prismatic scope designed for AR-15 rifles and carbines, featuring a clean T-Dot reticle with RDB illumination on the widely compatible H1/T1 micro dot footprint.

The T-Dot reticle strips away complexity and puts a single, precise aiming point in front of you — fast. RDB illumination pushes reticle brightness to levels that compete directly with dedicated red dot sights, keeping the dot visible and dominant even in intense direct sunlight. Thirteen illumination settings span from three NV-compatible levels through full RDB intensity, giving you a reticle that performs across every lighting condition you'll encounter. AutoLive motion-sensing technology ensures the illumination is live the moment your rifle comes up and conserves battery automatically when set down, so your optic is always ready without the worry of a drained battery.
