Video: The Most Compact, Fastest Crossbow on the Market?

When it's cocked, the Ravin R15 crossbow measures a mere 6 inches wide from axle to axle, yet it launches a 400-grain arrow at 425 fps. The secret is an innovative cable-management design called HeliCoil, coupled with a flight system that virtually eliminates friction imposed on the string and arrow by the rail. We get the details on how all this works from Ravin Executive Vice President Mike Weinkauf, who explains how the technology also improves accuracy at 50 and even 100 yards, then test it on javelina in Texas.
