When I was a kid and my dad gave me my first gun, he told me it was good luck to get a kill with the very first shot from your new firearms. I have been lucky enough to get a Kill with every new firearm with my first shot. I was able to do the same thing this weekend with my new suppressor.

I will admit, I expected it to be a little more quiet but I believe it is due to being on a AR platform. I am hearing the violent cycle of the AR which seems to be where the majority of the noise is coming from.
I have a .243 that has been my baby for the last 20 years. It is a Remington 700. I am debating threading the barrel. It is a fairly thin barrel. It measures just over 5/8 of an inch which I am guessing is about .620. I I am wondering if it is safe to thread it 1/2X28?
It also has a front sight that I would have to take off and put a screw in, to fill the hole.

Also if I want to measure the barrel length, where do I start the measurement from in this picture?
