Came across this. I thought this looked like a great idea, especially for those that have to perm attach a muzzle device to meet legal barrel length requirements:

I found this part intriguing
they are also already working on licensing agreements with other manufacturers to expand the range of Hub-friendly muzzle devices.
Perhaps there may be allowances for multiple brands of suppressors to attach in the future?
