I know a lot of DIY guys that blow away the average gunsmith. They usually have better paying jobs than gunsmithing, lol. There are a lot of guys out there calling themselves a gunsmith yet they do not machine, they do not file, they do not weld, and generally have no fabrication skills. Part installing and part swapping is usually their entire range of skills.
Good catch, I missed that part about the lack of tools and skills.
