The innovative Gun Boot 5.0 does not require the purchase of an additional mounting bracket- it"s built right into the Gun Boot 5.0 case! The universal built-in bracket mounts directly to your ATV rack and the innovative design allows for multiple angle adjustments. Quickly and easily attach your Gun Boot 5.0 to your ATV and just as easily detach it once you are at your favorite hunting spot. Our Impact model includes a removable, shock absorbing foam and nylon Impact liner that provides superior interior protection within our hard case. The outer protective case has an ergonomically designed handle and molded attachment points for a sling. Anatomically designed to accommodate left and right hand bolt action rifles and shotguns, it provides ample room firearms up to 51" in length, for 50mm scopes, and even rifles with slings attached.
