This is Charlie's shop service to install a trigger which you purchase from us, or swap a trigger or install a lower parts kit purchased from us inside an AR15 style lower receiver. This is only the service charge (labor) for this service.
We do not solicit armorer or gunsmithing service, but as a courtesy for our customer who are buying parts and need them put together, or for customers who may have purchased a rifle or lower receiver with mil-spec trigger and want to swap it out with a more advanced or preferred trigger, add this service to your cart, along with the trigger and the parts. If you are purchasing a complete lower with trigger, for military grade triggers, like Rock River, Daniel Defense, BCM, there is no credit for the trigger removed. There might be for Colt or FN, so ask our team.
