If the ASR mount comes in 1/2"-28 with a .30 cal bore, I would recommend that for your Omega, even if you are not going to move it to a different rifle.
I definitely wouldn’t recommend the Silencerco ASR QD mount on a mountain rifle. I have a Silencerco Omega and speak from experience.
1. The Omega comes with two interchangeable direct-thread bases, one for 1/2x28 and one for 5/8x24, so no adapter is required. Just unscrew one base from the silencer and swap it for the other.
2. Adding a QD mount also means adding a muzzle device. You’ll be adding an extra 1” of length compared to the DT base and an extra 3 to 4 oz. These seem like small numbers but they’re multiplied exponentially because of WHERE that extra weight and length is going: on the end of a lightweight barrel!
