The brand is not always the main feature that attracts people into buying an air rifle, but in many cases, it weighs hard on the decision. Just like with most products, certain brands are associated with power while others are the very representation of quality or durability.
However, this is usually a subjective matter as we grow attached to a producer following different reasons. For instance, I like buying Winchester air rifles because I am familiar with all their products and I know how they work. Still, this doesn’t mean all their products are worth my attention (or yours for that matter).
