Genuine Colt® replacement parts must be installed correctly to ensure proper function and safety. They are intended for installation on Colt guns only, and are not intended to be used in other products.
Genuine Colt® parts installed at the factory may be protected under Colt's Limited Product Warranty. Parts installed by other gunsmiths will not be covered. Substitution of non-Colt parts may void or impair your Limited Product Warranty. Colt will not accept liability for any subsequent malfunction or defect that in any way arises from, in connection with or as a result of the installation of a non-Colt part in a Colt firearm.
Unless you are a skilled gunsmith yourself, never attempt to replace parts on or repair or modify a gun in the absence of expert assistance.
