Shield Sights Announces the RMS-W Red Dot Sight

Dorset, England, U.K.-( Shield Sights is pleased to announce the release and full production of the RMS-W. The RMS-W is the water-resistant and ruggedized version of the existing Shield RMS line of sights.

The Shield RMS-W is designed to resist damage from water or other harsh environmental conditions. The RMS-W is gasket sealed to create a watertight fit between the slide and the battery compartment without the need of a special mounting plate. When the sight is properly mounted it will remain watertight at depths of up to 20 meters for 30 minutes.

The RMS-W also features a newly designed frame which adds thickness to the aluminum lens housing as well as a newly designed side profile. The RMS-W will also be the first sight in the RMS line to benefit from the newly developed hard coated polymer lens. These modifications have increased flex strength of the standard RMS sight by over 80% while maintaining the original viewing window and mounting footprint. The RMS-W will fit any slide that has already been cut for the RMS, RMS-C, SMS, or Jpoint.

The article states that the lens has been upgraded to a hard coded polymer lens. This might not be as good as glass but it seems they are addressing the scratching issue.

Literally EVERYONE who owns any of the now 3 iterations of the Shield RMS, me included, have had only one complaint about it, the lens. Why is Shield trying to reinvent the wheel with these hardcoat super special whizbang polymer garbage i stead of just making the lens glass?! There is a significant reason EVERY other quality red dot uses glass NOT polymer. Any piece of cloth laying around will perfectly clean my RMR while I have to run a cover on my RMS and use m.e.k. and Johnson cotton buds from the U.K. just to wipe a fuzz off… Read more »

Thanks for your comment. I was blaming myself for scratching the lens even though I treated the Shield the same as my other red dots.

You guys can reach out to Shield and get your lens upgraded. The company is pretty easy to work with.
Glass lens will be out late spring.


I had my lens replaced a few months ago by Shield and while I can attest to their ease of dealing with, the $70 price and 2-3 week wait time sucks, especially since it was replaced with the same easily scratched lens and they mentioned nothing about an upgraded lens option, either then or in the future. I am on my second lens and even babying the hell out of it and running a cover attached to my holster that pulls off upon drawing was still not enough to keep it from getting decently significant scratches. The scratches are much… Read more »

Good words, sounds like a great value.

I’ve been running a Shield RDS on a Glock 43 for about a year. Function has been good. I have noted the lens has scratched up despite my attempts to avoid that, so a better coating would be appreciated. It’s an always on sight and it’s needed 1 battery replacement in a year. Its small size is really appreciated on a small pistol.

Reach out to Shield Sights and upgrade your lens if its getting in the way of its functionality. If you can wait they should be releasing a glass lens in a few months.


Is this info coming from Shield Sights directly? I was about to just buy the RMS-W to replace my edc guns RMS and hope the new lens coating was enough of an improvement to justify buying it. This sight is absolutely everything that is great about a red dot as an option for an edc gun, except for the lens’ scratching and overly complicated cleaning process. (M.E.K. solvent and Johnson & Johnson cotton buds, since apparently, only Johnson & Johnson cotton buds will clean the lens without scratching it, according to Shield Sights) If, in fact, Shield Sights are making… Read more »
