Reply To: FX Crown/Impact regulator mod tutorial
That was when AoA was the US importer and service center, AoA is no longer the importer and primary service center. FX opened up a USA distribution and service center in NC with Earnst Rowe heading up the service end. I got this info right from him. So according to FX USA if you repair gun yourself FX will send you parts no charge under warranty. This includes changing the regulator like Weatherby has done.
I would say the only way FX would void warranty if user extensively altered or modified gun.
