I own a RIS II, and I have to say, it's a really good-looking clone. I'm all for clone items; they bring more competition to the overpriced name brand stuff. Unity riser and Wilcox mounts come to mind. What you're paying for here is a near identical copy of the RIS II and a decent free-float handguard. The FDE finish has this brownish glossy anodized look. For reference, the regular anodized FDE has a more matte brown appearance. Personally, I really like the ohhunt finish more. The lock-up is solid, just like the original, with no movement whatsoever. The metal seems a bit softer, though. It's shown nicks faster than the real RIS II, but it's as bulky as the original, so it gets the job done well based on design alone.
One thing worth mentioning is the finish and material quality. It's advertised as 6061-T6 Aluminum, the same as the original, but it noticeably nicks faster than the original RIS II. It's more about the finish than the metal itself. I installed it on a new build, and it quickly got scuffs before even seeing any range time. Attaching accessories also affected the finish. You could spray paint it or embrace the worn look, so I wouldn’t consider it a big issue. Guns get used, it's how it is. (UPDATE) After tossing it in the dirt several times to test its quality, the front irons I use (KAC micro BUIS PN:25654) have stayed zeroed. However, the finish practically came off easily. Take it as you will.
One issue I faced was with the barrel nut—it was a bad experience. It didn't fit the standard RIS II wrench or the improved classified defense wrench. Trying to torque it properly, I ended up stripping it. I started doubting if it was up to spec. Eventually, I purchased a DD barrel nut, which worked out. I could torque it properly and still enjoy the handguard. (UPDATE) They reached out about the barrel nut issue and fully refunded my purchase of the DD barrel nut. As it hasn't affected anyone else's installation experience at the time of writing this, I think it might have been a problem with my specific product. Still, their refunding the official part is above and beyond, and I'm satisfied in that regard.
I did encounter a problem with the handguard arriving with a droop/alignment issue. I managed to fix it using a few washers and shims on the lock-up screws. The shims were meant to address alignment issues but were not included with my item. Customer service offered to ship some from China or reimburse me for purchasing locally. It was extra effort and time I didn't look forward to. This left me feeling biased and somewhat resentful when I originally wrote this review, which I've since revised. I've resolved the issue myself. If you didn't encounter this issue with receiving your shims, you'd likely have nothing to worry about. I can only speak to my experience which led to me knocking out down to a 4 star.
tl;dr It's the best clone I’ve seen while still being a relatively decent handguard. My host of issues seems to be unique to my experience, but the customer service was willing to help after proper communication.
I also wanted an excuse to play with my camera.
