SHIELD RMS 2.0 EXCELLENT

by Jaboe1000, Verified Owner from VA, United States Written on May 22, 2026
With the correct K mounting plate on the Gen6 the site looks like it came from the factor. Sits low for co-witness, clear glass and crisp fast dot. Easy to mount excellent quality. Not sure why more people aren't purchasing Shield sights especially for Glocks. This is my second and NOT disappointed. Probably will buy a 3rd for another weaponn. Thanks Optics Planet great service

No Screws to attach the sight on the mount for a Glock 45 MOS mount

by Cliff, Verified Owner from OH, United States Written on June 24, 2025
The Shield Sight Reflex Mini MOA did not come with the correct screws for MNT-mos-SMS/rms Glock mounting plate. I had to contact Shield Sight to order screws, which are mailed from England. It will take 7-10 days.

Perfect for Springfield Hellcat Pro

by Neal289, from MD, United States Written on July 1, 2024
Enables use of fixed sights when mounted to Hellcat. Works fine, stays adjusted. I’ve fired approximately 500 rounds without any issues so far. Dot is always on and adjusts brightness based on ambient. So when it’s put away, led is very dim. After almost a year, no signs of diminished battery.
Pros:
  • Not from China (UK)
  • low profile clears fixed gun sights
Cons:
  • price
Best Used for:
  • Hellcat
Would recommend: Yes
