I agree with much of what
@Southern Lights said above.
Cans are another point of failure whether we like it or not. You do need to make sure it's tight or you risk a baffle strike. My cans get loose (barely) during range days, rarely when I'm out hunting but it always good to make sure.
I don't really baby my cans but they normally have a suppressor cover or a solo hunter rifle cover on when hunting. I am harder on my Huxwrx Ventum than i am on my Ultra 7. Never thought of someone denting a can but i guess it could happen haha. Mirage is a real thing here in AZ and it doesnt take many shots to heat up titanium, the cover helps a ton
Some guys will take a light profile barrel and get it threaded to accept a suppressor, leaving barely any steel for the suppressor to be supported by and essentially zero shoulder. Adding the suppressor (a 4-8" lever) to a barrel like that is asking for issues, especially if you're gonna be tough on your gear
I am happy with TBAC CB system. Its on/off pretty quick, uses a taper and i don't risk messing up my 5/8x24 threads on the barrel with the on/off all the time. Be wary other other QD options.
I Built my 7prc with the intent to use the Ultra 7 on it, went with a 22" carbon wrapped sendero contour so it can support a can without any problem and still handle well. While its an awesome rifle, my only wish is that i could have a folding stock of some kind, to reduce how much the can sticks up when hiking but then you're adding another failure point to the system
