Frequently Asked Questions
Q: What’s the best AR-15 sight for home defense?
A: Flip-up or Tritium-based night sights work best in low light. Consider pairing with a red dot and backup BUIS.
Q: Can I run iron sights with a scope?
A: Yes — use offset 45-degree sights or co-witness irons with a riser-mounted red dot.
Q: Do I need front and rear sights?
A: Yes. A full sight picture requires both. Many kits include matched sets, or you can mix brands if heights match.
Q: Are all these sights compatible with M-LOK or Picatinny?
A: Most AR-15 sights mount to Picatinny rails. Make sure your handguard or gas block supports the rail where sights attach.
