I have recently taken off the orange tip to my ASG Armalite M15A4 Sport line. Did NOT have any screw in orange flash hider so there is no damage to threads. However, I purchased a DBoys Stealth Full Metal flash hider. Both the rifle and new flash hider are 14mm CCW (Counter Clockwise). The flash hider is not screwing on at all or it will start then go crucid and stop. Any info would help.
