Sometimes. The QanT did, but I had to buy one separately for my Exia III, the good news is that they're usually like 2 bucks off Amazon. MGs and RGs definitely take longer, so I actually find myself liking HGs more with my limited time these days.

One of the few reasons I want to get into 30MM (30 minute missions)

Like I was telling Swattie, the cool part about 30mm is they were completely designed for kitbashing.
