I run my Omega on 3 bolt action rifles and 2 ARs. Running the Area 419 Hellfire system I've never had an issue with zero. It's similar to direct thread, more solid and makes swapping the can to different hosts quick and easy. Also it is shorter and lighter than the ASR brake/fh + Mount. Like mentioned above the flat front cap is also more compact. My Omega as is, adds 6" and is lighter. I love the Omega so far. Patiently waiting on 4 more form 4 approvals now. Hopefully Nov/Dec
