I've got the factory fiberglass free-float tube on my AR-10.

I received a JP AR-10 free-float tube as a "door prize".

I'd like to install the JP tube. I know I need a barrel wrench. Anything else?

Are there any especially good brands of barrel wrenches, and where would I find them?

MidwayUSA and Brownells both list wrenches, but I don't know how to tell a good one from a crappy one.
