Rifle cases come in various types of material ranging from:
Bar-Tacked Reinforcements - This is the most common type of construction and it uses a series of tiny bar-tacks to reinforce areas that are prone to wear and tear. This type of case is generally cheaper than others, but it doesn't offer as much protection against moisture or dust.
Heavy Duty Nylon Fabric - This is the most durable option, but it also costs more than other types of cases. It's resistant to water, dirt, and scratches. Plus, it's lightweight which makes transportation easier.
Molle - Molle is a type of webbing that's used to construct various gear items. It's also been used to make rifle cases, and it offers great flexibility in terms of customization. This type of case can be fitted with different straps and attachment points, which allows you to adjust the fit depending on your needs.
