Agree 100%. The barrel nut options get a lot of hate on this site, but I don't give a flying F. I'll use them as long as I can get them. I sleep well at night knowing that when I screw a new barrel on my action, I will have no headspace issues due to the tolerance stackup issues Frank mentions. The barrel nut allows me the ability to do that. Most of the people on here pissing and moaning about how it's SOOO much easier with a shouldered barrel are just lazy and whiners. As a mechanical engineer I deal with tolerance stackup issues every single day and the delays/headaches it can cause, so I choose to eliminate that in my personal rifles as much as possible. Using a barrel nut is the easy button. I laugh out loud every time I read a new thread on here where someone is describing headspace issues with their shouldered prefit.
Only reason I use barrel nuts is on the factory Remington actions. I have the recoil lug alignment jig and it's still more work than just screwing a shouldered barrel on.
Shouldered prefits have worked great for me, along with barrel nuts.
I do buy gauges and use them though.
