So I am about to buy a used Bushmaster rifle from one of the local individual (Washington). The guy is original owner. Everything seems good except one problem. The gun need a trip back to Bushmaster for a recall repair which Bushmaster will pay for the shipping. From what I read, Bushmaster will issue you a UPS return shipping tag and just send the complete rifle back to Bushmaster via UPS and it will be back to my door step in 3 weeks. Is it really that simple?? Do I need to send it out via FFL and have Bushmaster return the gun to a FFL?? Or do I have to have a FFL transfer the gun to my name before I send it out??
