So I'm working on a rather interesting project. I love the 6.5 rounds (Creedmoor and Grendel). I don't like having more than a couple guns in the same caliber as I just like variation. I have 5.56 covered with another AR and a CZ Bren 2. One of my favorite rifles I shot a while ago was an M16A4 (clone). The whole thing just shot smooth and felt really good.
I decided I want to build an M16A4-ish clone but in 6.5 Grendel. I got a 20" Doublestar chrome lined 6.5 HBAR since this gun will be more of a bullet hose than a precision rig. I now need to get a FSB preferably with the sight post already installed, and I need to have it pinned to the barrel. Where can I get a good quality FSB and who do you recommend to send it to to have it pinned to the barrel?
