An AR-15 brass deflector is a part that sits behind the ejection port and turns ejected brass away from the shooter. Ours sticks onto the factory deflector bump with 3M VHB adhesive, weighs 0.6 oz and is patented (U.S. Patent No. 9,664,468).
It fits Mil-Spec forged AR-15 upper receivers and is designed for 5.56 NATO and .223 Remington. Billet uppers vary, so fit is not guaranteed. Check the fitment FAQs if you are unsure.
No. Clean the factory bump, apply the included 3M adhesion promoter, then press the deflector on for 60 seconds. Let it cure 24 hours before shooting. Full steps are in the install guide.
Yes. The AR-15 ejects to the right, close to a lefty’s face, and the deflector turns that brass away. See our deflector for left-handed shooters.
Every deflector is made and shipped from Springfield, Oregon. Orders ship in 1 to 2 business days.
