Almost great - TRYBE Defense AR-15 Extra Lightweight M-LOK Handguard w/ Cut Away Rail

Overall, I do think this is a great handguard. Easy to install, and dang does it look good! The only gripe I have is that the pic rail DOES NOT fully match the dimensions of the Aero upper I have it attached to. The Trybe rail is a bit thicker, and the result is that my iron sights need to be adjusted to compensate for the slightly cross directional alignment between the front and rear sights. Fortunately, the difference in alignment here is minor enough to where I can still zero my irons - albeit with my rear aperture pushed far to the left. This is not an issue with the iron sights themselves, but with the size difference in rail width that forces my front sight to sit slightly to the side of the absolute center. All that aside though - it probably fits the Trybe upper perfectly, and the machining is excellent overall. Definitely gives a semi-sci-fi feel to my lightweight pistol build while remaining sturdy.
