Solid tool for 308 build - Geissele AR-10/SR25 Reaction Rod

I knew I needed one of these to work on a build I started. I hesitated when I saw the price difference between the ar15 reaction rod. The price is pretty high on these that's why I give it 4 stars. When I got a chance to use it I was surprised how robust is it. It's as heavy as my barrel. Worked great, no complaints. I hope I can use it more than twice.
