It's not a perfect answer, but it truly depends on your TOs. In my area it's not a problem, so long as people aren't aggressively abusing it by trying to pass off a grot as a meganob or something asinine like that. General attitude is if it looks like a special weapon, it is whatever you say it is - the key factor is quick identification of regular vs special weapons.
