JackO's Review of Magpul Industries MBUS 3 Front Rifle Sight

I purchased these for my department. We are issuing new rifles and I wanted a slimmer BUIS. These are noticeably thinner than the gen2 and fit the job perfectly. The slide on with little effort and, honestly, were 100% on zero out of the box. Couldn't be happier!
Pros:
  • Perfect Fit
  • Slim Deisgn
  • Great zero out of the box
Cons:
  • No side thumb button
Best Used for:
  • Any BUIS need
Would Recommend: Yes
