Will Maxicaps Void My Regulator Warranty?
Maxicaps do not change the form, fit, or function of any regulator, they are simply a protective cover. More importantly, it is a violation of United States federal law for a manufacturer to require a consumer to purchase their protection products to maintain your warranty.
