I know a lot about cans, but little about suppressors. I'm an impulse buyer and I plan on ordering one soon. Call it a graduation gift to myself... I'm looking at the YHM phantom series. Primary use will be on my SBR shooting .223, but I might want a .30 cal can for a bolt gun later. My big questions are... 1.) When you use a .30 cal can like the Phantom on the 5.56, what's the difference in reduction? 2.) Do ya think a .30 call phantom fit under my handguard (VLTOR CASV)? 3.) Which do you prefer, stainless or CM, and why? What's the difference in weight, maintenance, etc.? 4.) Should I be considering other brands?
