For the price this is a must have item an AR-9. Does a great job of deflecting gas and unburnt powder from your face. Also it is very aesthetically pleasing. I installed both of mine on Mil-Spec AR-15 uppers that have a forward assist. Perfect fitment.
Patrick Creed Verified buyer
This piece is made of cheap plastic and rattles loosely on the upper receiver. On my first day of shooting, this part broke. I'm searching for a better option. Can't emphasize enough how weak and flimsy the brass deflector is.

Excellent little gas shield. Helps significantly reduce gas to the face if you're running suppressed. I have one on both my AR22 and my AR9.

AT3 Tactical · Thank you for leaving a review for our CMMG 9mm and 22LR Ejection Port Dust Cover Kit with Gas Deflector. We're glad to hear that it's been a great addition to your PCCs and has helped reduce gas to the face while using a suppressor. We appreciate your support and feedback. Happy shooting!

Sean Weirich Verified buyer
This was a complete waste of money, the deflector is made of plastic and wobbles around. I'm not sure what the logic was behind this design but its useless. After installing I had to take it off. Ill use the other parts for a future build and repurpose them so its not a complete loss but the deflector is garbage. I could live with it being plastic but the fact that it has play in it and wobbles is beyond me, its only secured by the ejection port rod at the bottom, cheap design cheap part

AT3 Tactical · So sorry to hear that the item did not meet your expectations, Sean. I sent you an email to resolve the issue.
