I was searching for handguards and with all the selections am having trouble deciding. I want a carbine length free float tube. I don't need a lot of rails but enough for a bipod and sling attachment. Any advice or reviews on the hogue and Yankee hill brands. I was waiting on the local gun shops to get some Alexander Arms tubes in but my patience is running thin. I really need to get the glacial shields off before I can do any load testing.
