Rocket was bought by Trophy Ridge, and they do not produce the Rage. Rage is made by Field Logic (makers of the Block) and is its own company within FL. FL also bought Rocky Mountain Broadheads and will continue to be its own company within FL as well. I am sure they are sharing technologies with the slip cam developed by Mr. Barrie at Rocky Mountain that is used in the Snyper heads, but the retention of the blades in the closed position in the two brands of heads are slightly different. The Rocky (Snyper) uses rubber bands whereas the Rage uses a friction system with no rubber bands or O-Rings called the ShockLock system.
