The SLx MD-21 is an advanced micro dot sight that incorporates the latest technologies and materials to deliver exceptional CQB performance. Weighing only 5 ounces, the SLx MD-21 is both lightweight and rugged, featuring upgraded mounting hardware for guaranteed rigidity and precision when you need it most. If you are looking for a taller mount, check out the SLx 2.26″ mount for use with night vision or if you prefer a more headsup shooting position. The ACSS CQB variant comes with multi-reticle select allowing you to easily swap between the full reticle, chevron, chevron + BDC, or the chevron + horseshoe.
The powerful LED emitter features 12 total illumination settings and 2 night vision settings with an ultra-long runtime for full operability in any environment. Additionally, the AutoLive® technology shuts off the reticle when no motion is detected for two minutes and immediately turns on as soon as you pick it up.
The ACSS CQB reticle features three BDC dots underneath the chevron, allowing an unprecedented 600 yards of bullet drop compensation for 7.62 NATO or 5.56 NATO calibers in a compact red dot sight. Auto ranging and wind leads are also incorporated into this smart reticle. A CQB horseshoe grabs the eye instantly for close quarters shooting and also approximates the spread pattern of 00 buckshot at 25 yards.
