I am going to try this one more time. The question is "Quietest SUPERSONIC AR-15 caliber to suppress".
I have a AR15 Pistol with a 10.5in barrel. My Can is a Specwar 7,62. When, I shoot 208gr(SIG)or 220gr (Remington) Ammo all the noise is from the action. My CZ 527 300 Blackout 16 in barrel with the Specwar 7,62 the only noise is the firing pin falling.
I hope this helps.
