Sapphiros's Review of XS Sight Systems AR Mil-Spec CSAT Rear Sight

Nice sight, but unfortunately does not work with the MBUS Gen 2. It sort of fits, but facing one way is a bit loose, and if you reverse it, it doesn't sit vertically. Will definitely be using this for my (eventual) retro AR-10 build instead. It is Mil-Spec after all, so trying it on an MBUS wasn't guaranteed to work.

The notch is a bit wide if you have your rear sight as far back as possible and aim nose-to-charging-handle-style, but it isn't unworkable. Could just be me, though.
Pros:
  • Versatile
  • Well-Made
  • Crisp & clean
Cons:
  • Incompatible with MBUS Gen 2
  • Notch is a bit wide
Best Used for:
  • Mil-spec AR platform
Would Recommend: Yes
