L2D Combat Thread Protector Retainer Lo-Pro O-Rings
Prevent your thread protector from backing out while shooting by adding our threaded barrel retainer O-Rings to your barrel setup.
This is not your standard rubber O-Ring, these thin lo-profile O-Rings are made of Viton ( fluorocarbon elastomer ) and can withstand temperatures from -15 degress to 450 degrees fahrenheit. The material is also resistant to cleaning solvents, oils and other chemicals that will break down regular rubber O-rings. The retainer O-ring is not visbile when your thread protector is tightened into place and are perfectly sized to prevent movement.
3 O-Rings to a Pack.
