Gowutar emailed asking if I’d like to review their RMSc green dot sight, HHC17g. I was going to politely decline the offer, but I decided to see how far “affordable” Chinese optics have advanced thanks to “gain of function” collusion with the American gun culture and western engineers.
The budget friendly reflex sight, popular on Amazon.com, features a solid 6061 aluminum body. The glass is clear and distortion free. The green dot is very crisp. Wyoming’s environment tends toward the reddish brown so I definitely favor green dots over red.
Mounted atop the KelTec PR57, the deck or rear sight notch stands about 1/10” taller than some other optic options, but it is RMSc narrow…the rear portion doesn’t extend beyond the sides of the KelTec 57 NATO pistol or its mounting plate. The reinforced front portion does extend beyond the mount a bit.
I zeroed the optic at home using the Accurize Training Laser and then once at the range, my first two shot group was pretty close…just needed to shift the point of impact to the left.
The windage and elevation adjustment feature 1 MOA tactile and audible clicks. Some optics are mushy feeling making it a challenge to determine if an adjustment has been made. No complaints, love Gowutar’s clicky elevation and windage dials.
Standard shake a wake design is key for achieving the touted 50,000 hours of battery life. Gowutar stats say the 1632 battery is good for 160-50,000 hours. Maybe 50,000 if the pistol is kept locked in a bedside gun safe. But if carried, it’s not going to sleep. CCW?, I’d plan on replacing that battery every six months at a minimum. The battery is side loading so you won’t have to undermine the zero every time you replace the battery.
The operating temperature range from -4f to 140f is a bit limiting for Wyoming winters. Probably good enough for IWB carry, but might run into problems OWB when the high mountain desert drops to -40.
Go Wu Tar, it’s a close anagram of “Go to War” and while I would not consider this a go to war optic, it’s not a bad civilian CCW choice if you avoid frigid climates. Choose Green for arid regions, red for lush.

OSight SE is the budget friendly version of the original OSight S.
When I first heard about the SE from my media contact, I assumed it was a polymer housing version…kind of like Shield Sights SMSc with respect to the RMSc.
My presumption was totally wrong. The OSight SE is simply the non-rechargeable version of OSight’s original red dot sight. Actually…not simply.
The SE uses a replaceable CR1620 battery. That charging cover for the original was very cool and a great way for OSight to establish a foothold in the red dot optic market. But I expressed some reservations about the lifespan of a non-replaceable, rechargeable battery.
The CR 1620, smaller than the more popular CR 1632 or 2032, so it will need to be replaced more often. But with its side loading tray, easy to replace without risking your zero.
The exact same lenses. The exact same external dimensions. The exact same windage and elevation adjustments.
The SE is housed in a 7075 T6 housing. The original’s OAL aluminum alloy being OSights’ proprietary alloy that supposedly combines the best features of 7075 and Titanium. I prefer the SE’s 7075 over the metallurgical unknown of OAL
Just like the original, it has the same low, ¼’ deck height so is a great candidate for co-witnessing with standard pistol sights.
The same reticle options. Standard 2MOA dot, Circle, and circle dot. For longer battery life, go with dot. For hunting, I might prefer Circle Dot. However, the SE has no auto brightness…not a terrible loss given issues shooting from the shade into brightly lit targets.
SE includes the same OSight FN screw kit that will accommodate 99% of all mounting needs. The SE includes 2 spare screws for the battery compartment. Nice.
The same elevation and windage adjustments, so lacking in tactile or audible clicks..similar to Shield Sights so they could benefit from something like the Shield Mini-Wheel.
The same IPX7 1 meter water resistance is better than some. The operating temperature range is much improved with the SE. The original, the Osight S, was undermined by a limited 30 degrees F to 113 degrees Fahrenheit range. Presumably a limitation of the rechargeable battery. The SE has a far greater temperature range of -22 degrees F to 140. Able to endure Wyoming winter so I'll henceforth refer to the OSight SE as OSight Severe Environment.
Rechargeable was cool. But I much prefer the OSight SE…OSight Severe Environment.

MaddMacs Dovetail Base for the Ruger MK Series pistols is available in RMS or RMSc footprints.
This micro red dot base replaces the rear sight of the Ruger pistols. Removing Ruger’s excellent adjustable rear sight is kind of hard to swallow, but since most optics have some kind of built in “rear sight” we can hope that it delivers a zero at some worthwhile distance.
You could go with a center base and keep the stock sights in place as “backup irons”. But I’m not a huge fan of blending irons and red dots. Irons that intrude into the optics space tempt the eye to shift focus from the target. Better, in my opinion, to eliminate the irons altogether. Or at least have them down in the bottom fifth.
I also chose the rear mounted dovetail sight base over the center option to reduce the risk of causing ejection malfunctions…I suspect that there is some possibility of a case striking the mount and bouncing back into the action. Moreover, mounting toward the rear gets the optic closer to the “pivot” point…coupled with the MKIII 22/45’s high grip ratio helps eliminate searching for the dot.
Potential downside of the rear, dovetail mount is that the optic is more exposed to fouling. So far, after 300 rounds, that has not been the case.
Installation: loosen the small screw next to the elevation adjustment screw and then drive out the dovetail sight. I used a Wyoming Sight Drifter…unfortunately I broke off one of the sight blades. It must have been cracked already since I didn’t strike it or subject the rear sight to any real abuse.
The MaddMacs’ 6061-T6 aluminum mount matches the contour of the Ruger receiver, the long torx screw holds the dovetail filler plate (black edge forward) to secure the rear, remove the filler plug from behind the ejection port, and the short torx screw secures the leading edge. .
Paired with a Shield RMSc, Shield SMSc, or, here, an OSight SE, the optic sits cleanly atop the mount with just a tiny bit of overhang. A very clean looking installation. The rear dovetail mount is more likely to fit your preferred holster.
The mount has a very thin deck so the optic sits far lower on the pistol than if you used a Picatinny rail and RMSc Pic rail adapter.
One advantage of running a red dot on Ruger MK series or Browning Buckmark pistols is that the optic is not riding the action during cycling. It would be interesting to get some data on how this might improve longterm reliability or red dots in general.
The MaddMacs Dovetail RMSc mount paired with the OSight SE restores my appreciation for the Ruger MK pistols. So much fun and I can see maybe giving the old MK III a go at hunting snowshoe hares this winter.
Until Ruger mills an RMSc cut directly into the receiver, the MaddMacs DT mount is my favorite and arguably the best option I’ve found for running a red dot on the Ruger MKx pistols.

Osight S, from the OLight company, is a compact RMSc footprint, enclosed emitter red dot sight. It features a -proprietary “OAL” aluminum alloy housing that they compare to titanium and 7075 aluminum. The sight comes packaged with iPhone elegance..
The elegantly packaged sight is bundled with a complete screw kit that should get your sight mounted on 99% of every RMSc compatible pistol or mount out there. Very much appreciated If you ever had to track down the screws needed to mount a red dot on the Sig P365XL. If you end up choosing another sight, you just might want to order one of the Osight FN Screw Kits…available separately.
Osight S is a rechargeable red dot. That alone is pretty cool, but the sight’s most notable feature is the magnetic charging cover that when attached immediately shows the charge status of the optic. Remove the charging cover, you get the charge status of the charging cover itself. Charge the cover with the included USB-C cable and then it is then able to charge the sight 3 times. This is a very cool feature, but I’m kind of suspicious about the long term viability of the sight’s internal, non-replacable battery…just my experience with smartphones…batteries faltering after a few years.
And at my age, I worry that I’ll misplace the charging cover…so, I turned it over to my grandson to mount on his KeyStone Overlander.
The Osight S offers three reticle options….the standard single 2MOA dot, a circle, and a dot inside the circle.
The Osight S does offer the illumination auto adjust sensor which works fine when you are in the same light as the target, but when under a shaded cover shooting into bright light I had to boost the reticle a bit to see it well.
My grandson prefers the circle dot reticle, but if I were running the sight on a CCW pistol I’d probably just run the dot sans circle to extend battery life.
I found the sight a bit of a challenge to zero. Osight says that each “click” is one MOA. I’ve twice been sent to sensitivity training so It must be true, I lack sensitivity, since I could not detect a “click”...audible or tactile. There are tiny tics surrounding the elevation and windage adjustment screws. But trying to move the adjustment just a tick or two was challenging for me. Multiple times I overshot windage and elevation adjustments. Something like the Shield Sights MiniDial would be helpful.
I like the low deck height of the OSight, it is only .255” which places the optic window quite low on most pistols and allow many pistol iron sights to “co-witness” in the lower third or quarter of the sight. I was hoping it would be low enough to allow “co-witness” with the Keystone Overlander’s iron sight…not quite, with the circle dot reticle, I do see a rising sun…just barely missing the horizontal stadia. Personally, I’m not a fan of combining “back up irons” with a red dot since they tend to draw the eye away from being target focused…a problem for many shooters accustomed to iron sights trying to adopt red dots.
OSight S is available in black and olive green bodies…I think it makes sense to stick with black since you want that sight body to blur away with your focus locked on the target (with the red dot superimposed on it). Any color is tempting your eye to shift focus to the optic body.
The sight features IPX7 so it can handle immersion in a meter of water. The temperature range for operation is only 32-113 degrees F. Maybe ok for a CCW pistol, but we’ll push well beyond that backpacking the Keystone Overlander in the middle of Wyoming winter weather. We’ll see what happens.
Still, this is a great option. It’s affordable, rechargeable, versatile, and elegant.
