I need some info. I bought a stripped barrel with the intention of putting a lo pro gas block and a midlength handguard on my first build. I have steared away from that idea and now would like to put a FSB on that barrel. Problem is, I have no idea what to look, for being a newb. I have a Spikes M4 flatop upper if that makes any difference. Do I need an "F" marked FSB? Also the FSB works as your gas block as well correct? Any ideas where to find a FSB online?
Thanks Alot! |
