Welcome to Stalwart Arms, a custom shop dedicated to innovation in air guns.

We are the originators of the XS60C/Fusion repeater modification, their PCP 3K and 4.5K psi Thru-Tube conversion, and a variety of quality upgrades for the Beeman P3/P17, Xisico 120D, HW 40, and Snow Peak S400 pistols.

We offer custom parts and build complete custom guns to exacting standards.

We would be proud to build you something specific to your needs.
