The TrailMax™ Guardian Rifle Scabbard accommodates up to a 30 inch barrel and 56mm scopes. The rifle scabbard flap is designed for either maximum protection with a zipper closure or for quick access with a side release buckle. This nylon rifle scabbard is contructed of a high-density, waterproof foam and shielded by a tough 1,000 denier nylon shell. While most products with a zipper can not be considered truly waterproof, the TrailMax Guardian Rifle Scabbard is as close to a waterproof rifle scabbard as you can find on the market today.
