Change the configuration in any way you choose, and, again, there is no need to keep the original configuration. If you decide to make the change permanent (which is actually pretty hard in an AR-platform, but I digress), you can, as requested, send in a letter updating the registry, but it is not a requirement.So basically Put any size Barrel on it as you like? But keep your original one so you can return it to the original configuration? And if not you could notify them that you are permanently changing the barrel size due to you sold the old one?
