I waited on a rifle once for over a year, told myself it couldn't be rocket science, convinced the wife i'd be saving money in the long run (yeah right).
Bought a grizzly lathe and a mini mill, never used either ever, bought a little metal to practice on, now 15-20 rifles
, a dozen or so muzzle brakes, a bunch of gauging and measuring tools, some custom dies, a couple little cannons, a complete chasiss system, and some misc. stuff
I don't if I've saved any money but I can build two rifles for the cost of having one built, and if I decide I need something I have it in a day or two not months or years.
So far I still have all my fingers and a bunch of nice shooting rifles, there has been a learning curve but so far I haven't ruined anything.
So I guess if a dumba$$ like me can figure it out most anyone with some common-sense should be able to.
