Our lifetime warranty is a no questions asked warranty on our product! It covers damages including smashed ports, destroyed threads, or any other major issues! It does not cover the anodizing or cerakote due to extreme wear from everyday use or factory color! No two anodized compensators are the same, anodizing is an unstable and fluctuating process that we thoroughly QC! We offer a 30-day refund policy if the product has not been installed, Loctite applied, or damaged.
