Necessary Tool
Needed to replace a spring in an 40 year old 700 that was giving misfires from light strikes. The tool is simple and works great. FYI, the new 24# spring from Wolf was about 3 inches longer than the overly compressed original. Goes to show you how much the spring can age over time.

Firing pin spring tool
The Sinclair tool arrived in quick time. Good instructions are included. Worked perfect. A little oil on the threads made it even smoother to adjust. The Sinclair mainspring tool made disassembly and reassembly Eazy-Peezy.

Correct tool for the job
I am a new competitive shooter and needed this to replace a worn spring on a recently purchased used benchrest rifle. The action was a stolle panda. Simply put, if you need to swap out a spring on a Remington 700 or clone, you need a contraption to get the job done. This Sinclair tool works well and is reasonably priced.
