ar_glock9723NcStar BUIS budget option
Reviewed on May 5, 2026Verified with Build
NcStars pro series flip ups are about as cheap as you can go for a backup sight set. Spring detent holds them up positively. Front sight has tool-less adjustments which is nice. Wouldnt run them as primary irons but for a backup behind a red dot they work.

NcStar pro series flip ups go to 600 meters on the rear elevation. Spring detent holds them up firmly. Front sight uses standard A2 tools. Battery life isnt a thing on iron sights which is the point.
