The HM1000 I had came with the stock broken, AF sent a new one and it lasted two days before the dog ears that go around the regulator snapped off. The gun shot really well and was accurate but my overall impression was disappointing, attention to detail wasn't near the price point. The side lever had some play in it, the plastic magazine jiggled and the oversized moderator did absolutely nothing to quiet the report. I'm sure they have ironed out some of these problems in more recent models but that impression has really stuck with me. The one you had in the video looked like a fair improvement, certainly accurate.
