Details
The GLx MD-21s is a high-performance micro dot optic, built for superior agility and precision from close-quarters to intermediate range. This red dot features an advanced solar failsafe system, supplementing your power supply to ensure the optic operates with maximum runtime. On top of the solar failsafe, this red dot sight also features Autolive technology that turns the reticle off when set down for two minutes and immediately turns on the moment you pick it up. In addition, this optic features fully upgraded lenses, a new ultra-bright emitter, intuitive push-button controls, and a heavy-duty mounting system. Check out the SLx 2.26" Mount if you plan on setting up your firearm for night vision shooting or you prefer a more headsup shooting position. The Red Dot Bright™ reticle can be cycled through 12 different settings and is night vision compatible for full operability in any environment.
This rifle scope is part of the mid-tier optics line called GLx. GLx brings premium technology and materials into an approachable price range.

The full 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. Not only can you use the full reticle, but now you can cycle through just the chevron, the chevron and the BDC, and the chevron and the horseshoe to suit your needs.

Nice Optic
by Evan
Optic is nice but I am a little disappointed with the chevron. The chevron is too small to make out so it just looks like a dot. I'll have to view it under some magnification to see how I like it. The horseshoe is pretty sharp even with my astig. Brightness settings are awesome although I can't speak on the night vision settings because I don't have night vision to test them. Build quality seems solid and it has some weight to it. Overall I'm happy with this optic and can't wait to run it.
Good
by Greg Pears
So nothing really bad to complain on. Only wish the size especially the chevron was a bit longer on the wings. Can only be seen through a magnifier. And even with a 3x still looks small.
Not a terrible problem because to me it just looks like a 2moa dot and a small circle and I would have bought it with that as an option as well. I do have the Slx prism version and the GLX is half the Reticle Size. .
great red dot
by giverdabeans
Purchased this to replace my Holosun 503 Acss that recently died on me and I've got to say that is a great replacement. Quality seems great and glass clarity if fantastic, very very minimal lens tint if any. The recital is super crisp and looks great through my vortex 3x micro. All the new features are a plus as well. This is defiantly an upgrade to my old holosun and at a great price point too. Time will only tell how it holds up to some hard use though.
The best RDS for general purpose use
by Jordan
I never buy items without seeing a review, but I’ve been a supporter of Primary for about 4 years now so I figured why not. Shipping was stellar as usual. Received item 2 days early. Threw it on and yeah, this is probably the best optic I’ve owned period. I’ve tried many configurations with the PA 6x magnifier from vortex to holosun and even eotech but this beats them all, and does it easily. The vortex and holosun optics always appear very starbursted when under magnification, while the eotech looks clear but suffers from weight and battery life. This optic does not starburst, offers clear view of both the chevron and the bdc, comes in VERY light, and even has solar failsafe. Not to mention shake awake, which is something I enjoy on my holosuns. I’m astonished this item is being sold at this price, it is easily worth double. I will be replacing my other RDS with this as my wallet allows. Genuinely that good of an optic. God bless primary arms and what they do.
