Are "Single Stamp" ARs still a good idea?

This video discusses the viability and desirability of 'single stamp' AR platforms, often referred to as Short-Barreled Rifles (SBRs) that are legally registered under the National Firearms Act (NFA). The creator expresses a personal interest in owning one and uses this as a hook to explore whether they are still a sensible or worthwhile acquisition. While the description doesn't detail specific AR models, the focus on 'single stamp' implies a deep dive into NFA regulations, the practicalities of owning such firearms, and potentially a comparison of different configurations or the reasons behind their appeal.
