Diana Trailscout CO2 Semi-Auto Air Rifle

The Diana Trailscout CO2 Air Rifle is a lightweight multi-shot air rifle designed for recreational shooting, target use and pest-control applications. Powered by three 12g CO2 cartridges simultaneously, it provides convenient shooting without the need for spring cocking or PCP charging equipment. The synthetic all-weather stock, adjustable sights and compact handling make it a practical and easy-to-use platform.

Available in .177 and .22 calibre, the Trailscout uses a rotary magazine with 9-shot capacity in .177 and 7-shot capacity in .22. It features Diana’s Improved Trigger, a rifled barrel, manual safety and a milled prism rail for mounting compatible optics. Maximum velocity is approximately 660 fps in .177 and 560 fps in .22, with power of up to approximately 10–15 joules depending on calibre and market specification.
