That actual work is probably no more than an hour. It literally takes under 10 minutes to remove and install the barrel. It doesn't take 10 minutes to disassemble the bolt and put it back together, with maybe another 10 to adjust the firing pin.
The research time has been many, many hours. It took several phone calls just to figure out the recoil lug issues. I probably spent 10 hours reading and asking about barrels.
I've never been interested in doing bedding work. I'll buy a nice stock for it but don't plan to get one that requires extra work.
I may get a trigger eventually. There might even be lighter springs I can install. Honestly though, there's no creep or over-travel to speak of and it's adjustable down to about 3 1/2 pounds, which is where I have it. That's pretty good for a deer rifle.
