Torque only for a muzzle device

So I just got a YHM Phantom flash hider for my AK. I did not see any detents in the picture, but it only had 1 angle so I figured it was in a spot I could not see. I received the flash hider and no detents at all. Packaging said to go to the website for installation instructions. I found them, in their own section, no link on the product page. Apparently I am supposed to have a qualified gunsmith torque it, no crush washer, to 15-25 ft-lb.

I besides the issue of an ak specific device not having detents, torque only on a muzzle device seems like a bad idea? Am I incorrect in thinking this or is just torqueing it on ok?
I don't believe in "range fodder" that is why I reload.

Torquing is ok but I prefer the detent. There should be enough metal for you to just make a small notch for detent pin.

Depends on what the design calls for. Generally, what ever the maker's instructions are, done correctly will work and be reasonable durable.

Washer or not, I would not advise exceeding the given torque specs. Bad things can happen.
All else being equal (and it almost never is) bigger bullets tend to work better.

I have a few ARs that come with similar muzzle devices. They are symmetrical, so don't need be timed. No crush washer or anything of the kind. I suppose they are simply torqued on. No problem at all.

Torque is fine. You don't need a crush washer.
If you're worried about it, use some thread locker.

If you don't have a wrench that fits, stick a screwdriver through opposite ports (near threaded end, not danger end) and crank it down to "about there..."
Don't even try it. It's even worse than the internet would lead you to believe.
