This S510 is the larger XS Xtra version instead of the carbine, giving you just as much accuracy as well as more power and a larger air cylinder for added shots per fill compared to the shorter version. The smooth sidelever action and light trigger pull help you get accurate and repeatable shots, and Air Arms has added a regulator to the S510 XS Xtra line for added consistency.
