A proper carry handle and sight - Aero Precision A2 Detachable Carry Handle

I bought two of these and have liked both of them. The adjustment is a little tight toward the zero, but that can be compensated for by raising the zero slightly using the set screw in the elevation dial.

I was building an pseudo-clone M4 (upgrades from mil-spec to match grade for many parts, some style changes) for a veteran friend of mine, and bought the first carry handle for that build. Once I realized how versatile these sights can be, I ordered a second one for an upper of my own. If you are running iron sights on a gun primarily, the removable A2 carry handle sight is what all the flip-ups try to imitate, but most don't even come close to the simple elegance of the elevation dial combined with a carry handle.
