I explored that possibility as well. My upper is an AA 16" incursion (That I'm quite fond of so far) I too will be using an Omega on it after the stamp comes in. I called AA to find out what if any special disassembly procedure I should use on the rifle (mostly concerned about the hand-guard) to install the AGB. They told me the AGB is more trouble than it's worth and that most problems they see with their rifles is because of them. I had previously been led to believe they were needed if suppressed. I'd really prefer to be able to adjust it.
