QC Bro

A QC Bro is a firearms enthusiast who has amassed all of their knowledge from Facebook and Reddit forums. They are easily identified by their repeated usage of "Quality Control" to describe the inherent value of a firearm or firearm component.

They MAY have auxillary knowledge from several hundred live fire rounds down range at their local overpriced public shooting range, but it is more likely they have never operated a firearm in their lifetime.

He posted "AERO has serious Quality Control issues" in 13 Facebook Gun Groups today... That douche can is a QC Bro.
