Kaden's Review of Osight S 1x21mm Reflex Red Dot Sight

I have used several optics now. Sig Romeo X enclosed, Vortex Defender, Romeo zero. For the price point of this, as an enclosed emitter, reticle is very sharp, build quality is great, direct mount to Glock 43x MOS without plate. It punches well above its weight class. Would highly recommend and would buy again.
Pros:
  • Enclosed Emitter
  • direct attach no adapter plate
  • multi retical
Cons:
  • Auto Brightness feature is too dim for Daylight
Would Recommend: Yes
