Have an Omega 300 that I use on several rifles. .223 AR and bolt, 6.5 Grendel AR, .308 AR10, .243 bolt and .270 bolt guns. Works well as a universal suppressor as it is rated up to .300 WM. I use direct thread mounts and different end caps (to maximize sound suppression, reduce length and weight).
It is fairly light weight and compact, 14 ounces and 6" long with direct thread mount and end cap. Don't use the muzzle brake as the calibers I use don't generate that much recoil and I am trying to minimize OAL. The weight can be reduced an ounce or two more with titanium direct thread mounts and end caps. The Omega does generate some back pressure on the ARs. Not much blowback to the face, but more discharge out of the ejection port. ARs will need more frequent cleaning.
Have found that accuracy is improved with the suppressor, however, there is a POI shift with and without the suppressor. Once sighted in, I only shoot certain rifles suppressed. Taking the suppressor on and off, zero is maintained. Bolt guns suppress much better than the ARs. Overall, am pleased with the Omega.
