Used the world over, the Kolpin Gun Boot IV is top protection that's built to last. Constructed to accommodate right or left-handed bolt action rifles and shotguns with up to a 50mm scope and sling, the rugged, polypropylene shell provides the level of protection that your firearm deserves. Don't settle for less. It's also airline-approved for travel. Plus, it's made in the USA! Stop marring and scratches. The outer shell of your Gun Boot IV is built to be strong and durable. If you inserted your firearm directly into it and then traveled with it in your ATV, your firearm would be incredibly scratched and marred. However, inside your Gun Boot IV, you'll find the soft side of Kolpin. The ImpactTM Lining is specifically made to absorb shock and provide another layer of protection to your firearm. So, go ahead and hit those bumps on your ATV or take that jump off the mound knowing that your firearm is safe with Kolpin. Plus, it comes with a Bracket for your ATV / UTV. The Loop Bracket is the fastest, easier way to mount any Gun Boot IV or Gun Boot 6.0 Case on your ATV. Its all-metal construction and multiple angle positions make it both durable and easy to use. The rubber-coated ring and locking pin prevent additional movement and vibration, while keeping it firmly in place. Plus, it's compact to save room on your ATV / UTV.
