Sometimes there's a takedown pin that's pretty stiff and you need a punch to push it out but you don't have one handy. The one you have in your other tool bag is steel, which is unwieldy to keep in your range kit and will likely damage the pin's finish, which you might care about after spending serious coin on your new platform. Spare parts are hard to come by these days.

The new Composite Field Punch from suppressortools.com solves this problem. It's made of chopped carbon microfiber reinforced nylon, making the tool almost as strong as aluminum and practically weightless. The small loop on the side allows a parachute cord lanyard (dummy cord) to keep it handy with your other field tools. The butt of a knife or other object can be used to tap the larger end. The .20" diameter tip will work for all takedown pins and perform many other tasks.
