The new 1x  MRS Micro Reflex Sight lets operators engage targets with both eyes open, for wider peripheral vision, greater situational awareness, and faster response—critical when engaging moving targets. The 3 MOA red dot is easy to find and quick to aim, ensures either-hand shooting accuracy, and won’t obscure targets at longer distances.  At only 70 grams, the low-profile MRS is well-balanced on any shooting platform, giving shooters the quickness, confidence, and accuracy to control the outcome.

Micro Reflex Sight (MRS) is rated 4.3 out of 5 by 6.
Rated 5 out of 5 by from I'm using the Steiner MRS for hunting. Its size, build quality and handling is excellent. It combines a really tough, rugged design with low weight an compact size. The brightness of the red dot fits all light conditions and can be set automatically (what works fine) and manually. Other than Doctor Sights, Burris Fastfire etc. the MRS' red dot LED is protected against rain, dirt and snow. Nevertheless as any other reflex sights the MRS lenses has to be protected, what can be really hart when active hunting under some weather conditions like rain and snow. That's why I would really appreciate if Steiner would offer a lens protection cap for the MRS!

Rated 5 out of 5 by from Excellent Sight This sight is of great quality. Easy to use. Red Dot acquisition is excellent for its compact size. The battery placement is a plus. I am using it on a Sig X-5. I appreciate the integrated Picatinny rail mount as it mounts perfectly on my pistol.

Rated 5 out of 5 by from Perfect Profile For MP5 This seems to be made for the MP5 as it lines up perfectly with a low profile mount and does not sit higher than the iron sights as pictured.

Rated 1 out of 5 by from Not for use in sunlight :( When these were first announced I was very excited, I have owned several red-dots and was always disappointed with the bright sunlight performance. Well same here :( I like the size and the aesthetics but it just don't work in bright sunlight the reticle at it's highest setting is completely washed out (invisible)

What 3/4" and 1" spacers are size (length and width) compatible with the MRS? And What quick release base/adapters would be appropriate for it's footprint?

Asked by: LolaW
The MRS has a Picatinny mount fixed to the bottom of the sight. Any spacer would need to be a Picatinny riser or other Picatinny-style mounting footprint
