AR cyclic noise

[i8asquirrel]

Real expectations are the Key..
It may not sound like a Movie silencer but it quiter than you think if your the shooter. Many times My buddy and I will be seperated while hunting and I will make a kill and he wont have even heard the shot.
Being ready and listening for the discharge of a weapon or just having one fired when real world noise and events are taking place can make an amazing difference....

Just shot mine today...when I wasn't shooting I was standing 1-2 yards away; it seemed much quieter than when I was pulling the trigger.

Do you have the ability to turn your gas off? I turned my gas block to the OFF position for effect to show the other guys just how quiet it can be.

My load (for a 16" barrel) is: 11.5grains of IMR 4198, Sierra 190gr HPBT MK, seated to 2.235" OAL. The Temperature today was 35 degrees and this gave me 985fps. Speed of sound here today should be roughly 1090 fps. At 12.0 grains of 4198, some of the loads were going supersonic.

A Tubbs flat wire buffer spring will help with the noise.
