Excellent charging handle - Dark Storm Industries DS-15 Chinook Charging Handles

This charging handle came with my DSI DS-15 TYPHOON 300 Blackout complete upper receiver (DSI-UC5-TYP-T3-BLK) and the Chinook CH has functioned perfectly and I like it just as much as my Radian charging handles. Not sure what happened to the first guys CH but after sevral hundred rounds there's not a single scratch or wear mark on it but I keep all of my charging handles oiled with lucas gun oil. Honestly I wouldn't have bought one before getting it with my upper but I would definitely consider buying another when building another AR.
