Most Recent Reviews Worth adding to your toolbox by Will, Verified Owner, April 16, 2025
Over the years, I'm sure the value of gas block pins I've lost before buying one of these far exceeds the price OP's asking. If you find yourself installing gas blocks more than once or twice a decade, then it will pay for itself.
