Anyhow someone on this forum will have a good answer to just about anything except "Why do leverguns suck...?"

(just kidding really, I LOVE leverguns the best...!)
So...
1. I hear about different types of AR-15 buffers (i.e. "type 'H'" and so on which I assume refer to different weights). With the 300 Blackout or even regular 223 AR's, what are the options and designations and ideas on changing buffer weight vs. spring strength and so on (i.e. when would it be better to change spring vs buffer weight). I don't even know how to tell what strength springs I have in my various AR's - I didn't know there might be differences...

2. Specifically regarding the 300 Blackout, due to problems cycling subsonic loads reliably, especially if a suppressor is NOT hooked up, I understand some barrels have larger diameter gas ports, but whereas some folks say "you don't need to worry about over-gassing a 300 Blk", others of course say not to enlarge a port no matter what, and others offer fist-thumping opinions on exactly what diameters are the ONLY proper ones for given gas-system lengths ('pistol', 'carbine', 'intermediate', and 'rifle'). Is there any definitive info on such topics out there. It seems more 'reversible' if you screw up, to use a lighter buffer or spring, but on the other hand keeping the same buffer/spring in your lower and having a 223 upper and 300 Blk upper with the right port size to swap out on that lower makes sense too. And of course if you have an adjustable gas-block then that adds another variable...
3. Shooting regular 223 ammo in a chrome-lined chamber/barrel gun with a new bull-barrel and a suppressor on, every dozen rounds or so I get such hard extraction that it practically takes a mallet to pull the charging handle back, and the problem gets worse until I clean the chamber. The brass is dirty like an under-pressure 45 Colt levergun load, but this is not low pressure/subsonic ammo - it's regular stuff. Is that common...??? I have another upper I don't like as much, as the barrel isn't as nice, but it is a 'piston' conversion vs. the gas-tube-into-bolt-carrier kind. I suppose I could try the suppressor on that, but since the crud seems to be in the chamber rather than messing up the bolt/carrier, I'm not sure if there's any point in trying that experiment.
I know these are not 'levergun' questions, but I also know we have dozens of 'AR' fans on the forum, and probably dozens of 'suppressor' fans too. Even a few who have been fiddling with the 300 Blackout, I believe...
Just thought I'd ask a bunch of questions and see what kind of advice I get (other than "WHAT KIND OF STUPID QUESTION IS THAT, AND WHY DON'T YOU TRADE THAT PLASTIC MOUSEGUN IN ON A MAN'S GUN LIKE A 45-70 OR A GARAND...???"

(Hint - 'cuz I already have a 45-70 and a Garand.
