Something I usually do in the winter months is take each one of my firearms and clean it, even if it hasn't be shot for a while, inspect it, lube and wipe it down. I will then evaluate it to see if I need (or want) to change anything on it or just leave it the way it is.
That's how I got to where I am with my 9mm and 300 BLK AR pistols and wanting to change them over for suppressor mounting. So I am changing a couple of barrels and hand guards and getting some keymo micro mounting attachments. That way I can use 1 can for a while on multiple guns until I can get more suppressors!
And no, I do not have a suppressor.....yet.
