For‍‌‍‍‌‍‌‍‍‌ professionals and buyers, portable and easy-to-operate systems are among the key factors in the air rifle shooting and outdoor hunting industries. The weight of conventional air cylinders usually becomes a bottleneck that limits the users' mobility and their capability to use them for a long time. Snowrain has responded to this pain point by launching the Portable Aluminum PCP Cylinder, which through the innovation of materials science and structural design, has completely changed the portability standard for PCP air rifle systems.
