I really like this handguard! The machining is top notch and it fits seamlessly with my billet upper. The sleek visual design is matched by the cleverly engineered mounting system. The gas tube bushing is separate from the barrel nut so clocking is not an issue. I highly recommend purchasing the matching barrel nut wrench as it grips all four sides of the nut so you can torque it down without any damage or scratches. I'm also very impressed with SLR's customer service. I will definitely be buying from this company in the future.
