Are there any major downsides that someone who is just looking into SBR ownership should know? I have heard once you register a lower as an sbr, you can never sell it, is this true? Thats not a huge deal, because I plan on always having at least one ar15. I am really thinking of going the sbr route after my 21st burthday in a couple of weeks, but I want to understand all the pro's and con's before getting an SBR. Looking of any type of general input.
Thanks
