BUIS on competition rifles — rules overview (verify your book)

Competition rulebooks differ by org and division. Some iron-sight divisions disallow optics; some optic divisions allow backup irons; some equipment lists are silent. This page does not quote specific rule numbers or claim FBUIS-B is legal in any named division. Always read the current rulebook for your match.

What is safe to say

• Equipment legality is determined by the match organizer’s published rules, not by a product listing.
• A Picatinny flip-up aluminum set (FBUIS-B) is simply hardware—eligibility depends on division optics/iron policies.
• If backups are allowed, fold-flat profile and quick deployment are practical features; still confirm before match day.
