Hi, I'm Mark Serbu, lifelong gun nut, degreed mechanical engineer, gun designer, founder and owner and president of Serbu Firearms, Inc. I'm also a pretty decent self-taught TIG welder, machinist, CNC programmer and assembly guy. I'm trying to teach the basic principles of firearm design and engineering (which apply to ALL product design and engineering), including mechanisms, materials, heat treat, stresses, math, etc. Thanks for stopping by!
Due to the increasing hostility towards firearm content by YouTube, I'll be posting videos (which would be prohibited here) on other sites, mainly Rumble and Bitchute. Please see the links below.
