Mad Pig Custom's Enhanced Takedown Screw is based off their extensive experience with other takedown screw offerings on the market. They wanted a take down screw that didn't require tools, and didn't cut into your fingers. They designed this tri lobed screw that is designed to engage the pads of your finger tips, giving you better leverage to remove it or install it. It also has a convex design to prevent snagging while moving through the woods, or getting caught on slings or other gear during training or your hunt.
