The so-called Wrench Tool is used to fix the Delta Ring (this is the part that fixes the handguard on the M4 or M16) and the Stock Tube. The tool is made of metal and is also suitable for situations where a lot of pressure has to be exerted. However, it should always be kept in moderation and not tightened too tightly as both the Delta Ring and the stock tube could otherwise be damaged. Particular care should be taken with Systema PTW or other rear-wired rifles as sharp edges on the stock tube can cut the cables and cause a short circuit.
