Okay, so lets say occasionally that I order/obtain and off roster gun from out-of-State that can be converted into a SSE. It arrives and I commence modification i.e. dropping parts in to make it a SSE. I then DROS it as a SSE to myself and transfer it into my personal collection. Once it has been transferred into my collection I want to modify it to 10 rounds. Problem???
Thanks for taking your time to answer my questions.
