Check the listing for details. Davidson Action Wrench for Remington 700 Right and Left Hand. Condition: New. Listed at 79.00 USD. The Davidson Action Wrench is made of 12L14 mild steel and zinc plated. Designed to fit the Remington 700 action, it emulates the bolt lugs and has two grooves cut to allow for the bolt release and fits both right and left hand actions. A 3/4" hex is machined on the end for a wrench or socket. The hex end is also machined to help clear a stock with a high comb. It's overall length is 8.5" and the portion that enters the action is 7" long. This wrench will fit other actions that have the same bolt lug dimensions as the Remington 700. See the pictures above and measure your bolt lugs. If yours are smaller then it won't fit. We make our wrenches .984" diameter x .435" thick. This wrench is not warrantied when used to remove a factory tightened barrel for the first time or when a cheater bar is used. My dad designed this wrench in the 1970's to fill a specific need. He was an avid bench rest shooter and needed a wrench to switch barrels on accurized Remington 700 actions. We make them out of 12L14 mild steel just as he designed because it won't harm the action and it is easy to machine. With that said, they have been used successfully to remove factory tightened barrels, it's just not what they were designed for. We have had two customers purchase a replacement wrench for one they twisted while removing a factory tightened barrel but they admitted they were using a very long cheater bar at the time.The Davidson Action Wrench is made of 12L14 mild steel and zinc plated.
