Good vice and a good punch set, and then an armorer's wrench (castle nut, barrel nut, etc) are the main ones.ag0207 said:
With all the sales I jumped on a new stripped upper & lower. This will be my first complete build. What tools do you guys consider essential to have for a complete build?
Having a good assortment of allen wrenches, screwdrivers, and hex heads lying around helps too.
You can get by with a standard workshop with tools if you are fairly mechanically inclined and creative. I've used a long, sturdy nail as a punch before, for example. Obviously much easier with the correct tools.
