The benefits and unique features of the Original Barrel Bumper are: When used in conjunction with a firearm that has the Original Rifle Reel & the Original Barrel Bumper it clips onto the muzzle-end of the firearm preventing the barrel from packing with mud or foreign objects. While walking with a muzzleloader, the Original Barrel Bumper can be clipped onto the gun to keep moisture (i.e., rain, snow) from fouling the black powder or Pyrodex pellets. When taking breaks between morning and evening hunts using a muzzleloader, the Original Barrel Bumper placed on the muzzle end will remind everyone that it is a loaded firearm. They are reminded because only the cap can be removed. The Original Barrel Bumper has a slit on one side so iron sights/fiber optic sights are not affected. Photoluminescent pigment is added to the injection molding process, causing the barrel bumper to GLOW-IN-THE-DARK when light activated. This allows it to be used as a beacon while walking through the woods in low light or transporting game. It also gives you excellent depth perception while hoisting or lowering firearm from elevated tree stands. The Original Barrel Bumper also has big butterfly clips for easy installation and removal even when wearing thick neoprene gloves.
