EchoCore Sector 556 on a 10.5" and 20" AR-15

The Echocore Sector has a really interesting design that works very well on high pressure rounds like the 5.56 and 6 ARC. With two hosts to try it on, I discuss the diferences on a long and short barreled 5.56 rifle. Limited shots are done in this video to preserve my hearing. No matter how good, a suppressed 5.56 is NEVER hearing safe. One or two shots may be OK, but beyond that it is all hyperbole. Don't let a GunTuber tell you otherwise. The supersonic crack is damaging and the shorter the barrel the closer that crack is to your ear. Always shoot with ear pro on supersonic rounds unless the situation does not allow. Cheers!
