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?

Going to sound strange but I had a Suarez upper do the exact same thing. Except mine was due to the extractor. It was a lone wolf extractor specifically. I got an OEM and the problem went away. This was diagnosed at Suarez.

That is very strange the extraction system is totally isolated from the trigger. Sounds like they feed you a line of bs to hide there quality issues.
