Hand guards have been explained numerous times on this forum. Search around and you'll find some good information. There are many good brands out there and most will fit. Installing them is pretty easy. I found this link that did a good job of explaining the installation process. I bought the same ones that are on my link. Find some that look cool to you. If you have any questions about compatibility, post it on this forum and I'm sure someone has the same ones and will be able to help you.
I have been very happy with my Tusk hand guards. I bought these in black.
