I'm rolling around the idea of my first SBR. I'd like to build/buy something that could serve as a HD weapon that I'd work toward eventually getting a suppressor for, but also something that would work as a decent general purpose rifle as well. That's why I thought something "mid size" would be worth considering. Short enough to still be useful with a suppressor indoors, but not a super shorty. Also not something too long that starts knocking at the back door of a 13.7 or 14.5 pinned and welded.
I also really like the look of the SBRs that have FSBs and quad rails. I doubt I will ever have a need for night vision, so the quad rail is probably not any better than a slim rail, but I just like the look. Anyway, looking for suggestions and recommendations on barrel size and configuration and any tips on best places to make purchases.
