Anyone have any experience with Faxon Firearms barrels with integral brakes? Do they really serve a purpose? The breaks are sized to match the barrel diameter, so you can fully assemble and disassemble your rifle (i.e. change gas blocks and barrel nuts) without having to try and remove a pin/welded break, since the integral break is the same diameter as the barrel. Seems like it might be a solution for those of us in restricted states that would like a break (I.e. not just an unthreaded barrel), but like to easily swap out the gas port and barrel nut. Joe Bob is having a sale on them.
