where to find a A2 pinned fsb

[TheM4chef]

So I'm working on the final bits of my new build.

Spikes lower, BCM upper with 14.5" DD chf barrel.

Now I'm trying to decide if I want a fixed sight or put a low pro gb and longer ff quad rail. I've been looking around and can't find one. Are they manufacturer specific or am I just lacking proper searching skills?

Check Wolverine..I'm pretty sure they have the Armalite A2 FSB's in stock. And I'm pretty sure I saw them at ArmsEast...those are the Stag ones.

Ok I didn't realize they have to be drilled out to install. Can a used one be installed on a different barrel without issue?

Na each one is unique to it's barrel. You can use set screws if you have to recycle one - I drilled and tapped mine and used a couple 4mm(?) grub screws to pull it tight to the barrel. A virgin one requires precise fitting.

Well that kills that idea. Low pro gb and full length quad rail it is!

Skip the quadrail and go with a round FF forend with a continuous top rail and shorter removable rail sections just in case you want to hang a bunch of junk off the end of your rifle. They are lighter and much more comfortable.
I had a Samson Evolution on my 18 inch AR and it was awesome.
