Railed hand guards are a great means to mount accessories to a rifle. However they can get in the way when you don’t need them. They can tear up gear and barricades if they are not covered. Additionally the rails can be damaged to the point that they no longer accept accessories.
Kwikguard Rail Covers are a simple way to keep your rails safe when not in use. They are made in the USA and come in a variety of lengths and colors.
