More power to them. The main reason I don't like it, is because while it is "cool" and DIY-friendly, it is also eliminating the need for a gunsmith...Which the more DIY stuff comes out, the more gunsmiths will become obsolete. For those of you who don't have one nearby, or don't really know your gunsmith on a personal level, like I do, you don't get that same respect for them as a person, as you would if you went to their shop, saw them work, shot the bull, and really got to know them as a person. Most folks just think of them as that dude in another state, who's taking a year to build my rifle that he's gonna charge me a fortune for his time and labor.
It's just 1 more step into doing away with true craftsmanship, IMO. Gunsmiths are artists. And the more we eliminate the need for them, the more that art form will die. And when it's dead, it will eventually become extinct. And then it becomes a **** shame to see that technology has traded-off true craftsmanship and skill, for any random idiot in a garage with a monkey wrench and a vise. No offense to anyone, just using that as an analogy.
While I am all about DIY, and learning to do everything I can. I am/was a metal fabricator by trade, and was for most of my life, and I have watched how robotics and technology have basically killed-off the job market for people with my skills. I don't want to see the same thing happen for gunsmiths...But that's the direction we're heading.
