Western Airguns Sidewinder – Semi and full-auto PCP air rifle with bullpup design

The Western Airguns Sidewinder is a PCP air rifle featuring both semi-automatic and full-automatic firing modes. This 3.5 kg bullpup platform combines a polymer-metal construction with a 580cc cylinder operating at 300 bar to deliver 95 joules in 5.5mm calibre.

Construction and materials

The Sidewinder utilises a bullpup configuration with a polymer-metal hybrid frame weighing 3.5 kg. The 580mm TJ hammer-forged barrel ensures consistent accuracy. An internal regulator maintains shot consistency regardless of remaining pressure. The removable magazine holds 15 rounds, while the included moderator reduces report.

Application and use

This air rifle suits advanced shooters requiring rapid target engagement capabilities. The semi/full-auto selector switch sits behind the breech block for seamless mode changes. The single-action trigger provides predictable response in both firing modes. Suitable for precision shooting and dynamic disciplines where rate of fire matters.

Integration and compatibility

The Sidewinder features both Picatinny and Weaver mounting rails – the 22mm Weaver top rail accommodates optics while the bottom rail supports bipods. The ambidextrous design suits both left and right-handed shooters. This PCP platform is slug-compatible, expanding projectile options beyond traditional pellets.

Maintenance and lifecycle

The internal regulator requires periodic servicing to maintain consistent velocity. The 300 bar fill pressure demands proper equipment and safety procedures. Regular cleaning of the barrel and magazine ensures reliable cycling in full-auto mode.
