Details
Details
The Primary Arms SLx MD-20 Micro Red Dot Sight is the perfect blend of the advanced technology and features of the SLx MD-25 red dot and the form factor of the wildly popular MD-ADS! The newly designed body is aggressively styled and features low-profile, shielded adjustment turrets to minimize the risk of snagging in rifle cases or the bush. The new high-power emitter provides true Daylight Bright settings on the high end yet retains both night vision compatibility and the 50,000-hour battery life you have come to expect. To further boost that battery life, the SLx MD-20 is equipped with AUTOLIVE™ motion activation. This feature turns off the optic when not in use and immediately comes back to life when it is moved, extending both the battery life and the life of the emitter. Compact, durable, and powerful, the SLx MD-20 is the perfect optic for your next build!

It works for 5.56
by nick -
I wanted this for my 300BO but that was a waste of ammo. I'd boresight it, shoot, miss the target and recheck with the boresight and the dot would be waay off. Went back and forth a couple times thinking I was the moron. Gave up and put it on a 5.56 build and it seemed to hold zero. Will reconfirm next range trip. Should've stuck with aimpoints
Great Quality sight!
by Michael Bone
Straight from the box you can tell the difference in this sight. Workmanship is of the highest quality. Simple to operate with quality features. The buttons for the sight are easy to operate from brightness adjustments to windage and elevation adjustments. They respond quickly but aren’t bulky like other sight manufacturers. The glass is crystal clear and the anti-glare coating helps when using the sight in the sun. The red dot is easily visible in all light conditions. The battery life is unmatched. I leave mine on and have had it now for 8 months and it still keeps lighting up the targets. The reflex sight is solid and the red dot does not bounce and have to resettle like other Red dot sights. You won’t go wrong with this sight. Sight is rugged and holds tight to whatever you mount it on. Have mine on a Glock MCK. All future builds I do with have this sight on them.
Works great
by Joel
Love it. Better than most. Very easy sight in and audible clicks. Going to buy more.
Best red dot on the market for the money
by Mark -
These have become my favorite red dot. Simple, reliable, robust, and obviously affordable! The bottom of the lens is cut lower than any other micro dot on the market, so they are perfect for anything that has a stock/brace lower than the top picatinny rail. This is the only dot that will absolute co-witness with Galil Ace Gen 1 irons and any Scorpion-style sights. Also lines up with the front sight post on a PTR. Primary Arms knocked it out of the park with this one!
Great Budget Micro Red Dot
by Eric A.
This is a great, lightweight, tough micro red dot. I put it on my Ruger Super Red Hawk, and zeroed it in at 25 yds. Once zeroed, it held perfect zero after another 25 rounds of full-load 240 gr. .44 magnum. Plenty of brightness on sunny days, easy to operate, and clear glass. Best deal going for a budget red dot. And as usual, great price, service, and shipping by PA!
Great Budget Micro Red Dot
by Eric A.
For the price of this optic, it can't be beat. I hesitate to even refer to it as a 'budget' red dot. Compact, lightweight, and tough as nails. Clear glass, crisp dot, and plenty of illumination even on the brightest of days. I prefer the push button controls as opposed to the knob for on/off & brightness settings. The 'shake-awake' feature just adds to the value. Turrets track perfectly. I have it mounted on a Ruger Super Red Hawk, and it holds zero round after round of 240 gr full magnum loads. As usual, great pricing, service, and fast shipping by PA.
FEDEX
by George -
First off let me say that I've always had good experiences with Primary Arms. Quality products and good service.
Fedex on the other hand has become more and more undependable.
great optic for the price
by s ward
I mounted this on the gastube of an ak. It co-witnesses perfectly. A nice crisp dot on target. I bought it off amazon like an idiot, the primary arms website is much cheaper.
Quality optic
by Andre
For a brief moment when I first pulled the optic out of the package I thought they forgot to put the glass in it, it is THAT clear.
The dot is crisp, the turrets are solid, and the push buttons for the brightness are interesting (all of my red dots prior to this used knob selectors for the dot). The auto on/off function works nicely and is a great feature. Turns off after a minute or so of the firearm being left alone and then turns back on as soon as it is moved.
I’m just an average Joe with a cabinet of guns. I’m not a YouTuber or gun snob who needs the latest and greatest. If you’re like me and just want a solid red dot with clear glass and durable build quality without spending hundreds of dollars then I don’t think you will be disappointed if you opt for this one.
Great Micro Red Dot
by Andy -
This red dot exceeded my expectations for the price that I paid for. The quality is so nice I would buy it again for another rifle. It’s not bulky or big. It’s the perfect size. The great part is it’s not expensive either compared to most other optics. It really helps with target acquisition. I also love the looks of it mounted on my AK! I would literally have my AK hanging on the wall mount and stare at it all day.
