Customer Reviews

Based on 3 reviews

A little tough removing the rear sight but installation of the Burris fast fire mount for my Beretta px 4 storm was easy, I did use a sight remover instead of a brass punch an hammer

Thank you for your review. We're glad to hear that the installation process was easy for you and that the mount works well with your Beretta PX4 Storm pistol.

Red dot mount

I have a PX4. unit fits well and easy to mount, only thing was that I had to enlarge the hole for the pop up reset pin.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
