And if I’m honest I may have a pro screw this first one together, although this one shouldn’t be too too bad since I have a complete upper, but still. Haven’t decided for sure yet.
The lower isn't bad to assemble, but it really helps to have a vice, torque wrench, and castle nut wrench, if nothing else. I'm not sure of many ways you can get around having those specific tools for the buffer tube assembly.
