We currently offer a limited number of accessories and factory replacement parts for Xisico and Industry Brand Chinese air rifles. We offer custom made parts for these rifles as well and can supply items such as modified triggers and custom front and rear spring guides on a made to order basis. For factory stock parts and custom made parts, contact us using our contact page or call us at 515-924-3699 to learn more. Because of the small size and low volume of most replacement and custom parts, we cannot offer free shipping on these items.
