I bought an Omega for my 300 BLK SBR a couple of years ago and it's really nice with 300 BLK subsonic ammo. I built a 6.5 Grendel SBR recently and I've been using the Omega on it with great success. So far I've only shot Hornady Black ammo in the Grendel. Since Hornady Black ammo is not subsonic, I can hear the sonic crack downrange, but it's hearing safe without ears at the gun.
