1. So why do most people opt (it seems) for the 14.5 inch barrel?
- Ease of movement, less weight, yadda yadda?

2. To get a 14.5 inch barrel with a removable FH, I'm assuming you'd have to get SBR paperwork?


Just want to make sure I understand things correctly. Thanks.
essentially the way it reads is that the fixed length of the barrel cannot be less than 16 without an SBR Bribe. If you have a 14.5 and permanently add a 2" FS you are in compliance.

The reason I think some opt for the 14.5 and then perma-mount the FS for 16.5 is so that they are as short as possible without SBR. With a 16" and FS you could come out well over 18" depending on the FS you buy.
