I have a Wolfman, which is slightly smaller than the Nomad. It fits in Seekins Precision handguards and they are compatible with the Aero M4E uppers. The Aero Enchanced handguards are squared off on the inner wall, whereas the Seekins are perfectly round. The Nomad should fit the Seekins handguards (barely). However, if the barrel is not perfectly concentric to the handguard, the can will likely touch one of the sides of the handguard. Also, you cannot use any of the MLOK slots around the can (obviously).
