What are the best AR-15 sights for home defense?

For home defense, a combination of Tritium iron sights and a co-witnessed red dot sight is ideal. Flip-up BUIS can serve as reliable backups in case your optic fails.

Can AR-15 iron sights co-witness with red dots?

Yes. Using a riser mount, you can co-witness iron sights with red dot optics. Choose between absolute and lower 1/3 co-witness depending on your preference.

Are flip-up or fixed sights better?

Flip-up sights are great as backups for red dots, while fixed sights are ideal for always-ready use on duty or training rifles. Your choice depends on your setup and use case.

Do you offer Tritium night sights for AR-15?

Yes. We carry Tritium-equipped AR-15 sights that glow in the dark and provide enhanced visibility without batteries, perfect for defensive and low-light conditions.

💬 Frequently Asked Questions

Q: What are the best sights for a home defense AR-15?
A: We recommend fixed or flip-up iron sights with Tritium inserts for 24/7 readiness. Pairing with a red dot sight and co-witness riser is ideal for speed and reliability.

Q: What’s the difference between M4 and HK-style sights?
A: M4-style sights use a traditional squared post. HK-style sights include a circular hood that helps with alignment and protects the post from impact.

Q: Can I use iron sights with a red dot?
A: Absolutely. Use a riser mount to co-witness your red dot sight with your BUIS (back-up iron sights). Choose absolute or lower 1/3 co-witness based on your preference.

Q: Are flip-up sights better than fixed?
A: Flip-up sights are ideal as backups to optics. Fixed sights are better when used as primaries or for duty applications where readiness is critical.

Q: Do you offer Tritium AR-15 sights?
A: Yes. We carry several models of Tritium-enhanced front and rear sights that glow in the dark without batteries – ideal for low-light defense or duty use.
