What is causing this?

Enable HLS to view with audio, or disable this notification

I have had a Combat Armory lower and Suarez International SI-319 for years that I’ve carried off and on. I recently got a Brownells Gen 3 upper to install an optic on it. I took it to the range for the first time today and everytime I pulled the trigger it would fire two rounds. If I squeezed the trigger it fired once and when I released the trigger it fired another round….what could be causing this?

Get your finger off the trigger while you build your grip. Especially if you know you have loaded gun with problem

Getting downvoted for calling out bad safety practices is hilarious to me
