I dont want to hijack the thread, but why is FFL not necessary for such a repair? Is it because a large quantity of parts might not be shipped with the gun and item to be replaced? I thought that any time that a gun was to be shipped, even if it was just to the manufacturer/gunsmith and back after repairs, for an item YOU OWN, an FFl was still required as the go-between.
That not being the case opens some new doors as far as customization and service goes, considering my location and the hoops that must be jumped otherwise...
Thanks and sorry for hijacking the thread...
