A buddy of mine owns a few miles (not just acres) outside of town ... the club I belong to doesn't allow FA so its one of the few places I have to shoot my M16.

The quietness started with my Colt Sporting SBR; a generic upper with a 8" barrel in a 12" tube ... For now it's using the YHM Ti 30 caliber can. Next was the AR-57 on the M16 lower ... I just got a F/A bolt, runs beautifully with the right buffer using both the Octane 45 and the F1 9mm pistol suppressor ... The only thing that is easier to control in FA is the CMMG dedicated 22 PDW upper which was next; It's so easy to control you can write your name in F/A; I ran a few rounds through the G-19 a bit too with my Form-1 can, and lastly was AUG A2 ... also quieted with the YHM Phantom Ti 30

... Anyway, it was a very quiet day!
