Radian Raptoe-SD Charging Handle
Very smooth operation, the NP3 coating makes operations effortless and there is fouling in my Piston driver M4 Clone. As such I've enjoyed worry-free operations, an E-A-S-Y pull back with the oversized and low pressure wings . As a disabled Veteran with Arthritis, I have limited hand strength. This Charging Handle is the easiest hardware I've ever used. An absolute 5 Stars and well worth the cost!
